Slightly over your budget but a better headset:
I AM Cardboard DSCVR Headset
https://www.amazon.co.uk/dp/B018G17K52/ref=cm_sw_r_cp_api_IYeCxbTAHEVFK

Over budget but the best headset in its price range (button is a bit iffy on iPhones though for some reason)
BOBOVR VR Z4
https://www.amazon.co.uk/dp/B01CEBKXJK/ref=cm_sw_r_cp_api_oZeCxb4ZVCA18

I own all of these, they all have the button and work with iPhones. I had to modify the button on the BoboVR to get it to work properly though.
The Viewmaster is ok, the field of view isn't great, and it looks a bit kiddy, but it is robust and has good clarity.
The DSCVR is pretty much just a plastic version of Cardboard 2.0, but sometimes the more straightforward the better, I found it very good, although the strap that holds the phone looks like it will wear overt time.
BoboVR is by far the best though all round, great comfort, great fov, adjustable lenses (which the other 2 don't have) and the headphones are actually really good.

I got the same viewer, but there's no fix for it with custom codes. Spacers don't work either. The problem is that the lenses are terrible.

I ordered replacement lenses for it, and they're a vast improvement. I wound up ordering two sets. Both are about equally good; one is much cheaper, but takes much longer to ship.

Oops! The cheaper one no longer seems to be available. It was made by "TOOPOOT," and was a 37mm x 45mm lens. TOOPOOT now seems to make their own Cardboard viewers, so maybe they've decided that's a better solution.

More expensive, but available with Prime shipping: https://smile.amazon.com/gp/product/B012HYF4A2/

These are specifically suited to the Minkanak, as it's got larger-diameter lenses than other Cardboard v2 viewers.

I've since upgraded to a BoboVR Z4, though, which I find much better in most respects. The lenses are quite good out of the box, and the IPD and focal adjustments are a great addition--I can use it without my glasses, and I'm quite nearsighted (-7 in one eye, -5.5 in the other).

For what it's worth, this is the best profile I was able to generate for the original lenses before giving up. It's got major and irreducible bulging.

Hope this helps.

Edited: Can't get the "data" protocol to show up as a link.

Edited again: Tested the "cheaper" link and it's dead. I guess TOOPOOT doesn't sell them directly anymore.

Cardboard will not work with any regular games, since it requires the display to be split into two separate images, and looking at a regular game in Cardboard is a good way to induce headache.

I don't know of any head mount like the one you are looking for, but it is pretty easy to build one yourself with an existing cardboard box. Just make sure you use one large lens with about 3X magnification and place it about 10cm/4 inches away from the screen.

By using one lens (e.g. a rectangular fresnel reading loupe, preferably the size of your screen) both eyes will easily see the full screen. This doesn't work well with two lenses like in Cardboard, even if you use lenses with much larger focal length/lower magnification, as you will get a lot more distortion when looking through the edges of the lenses, or your vision will be completely blocked. The primary function of the lens here is not to make the image larger like in VR, but to allow your eyes to focus on the screen at close distance, so you can actually place into some kind of headset.

I tried it with a handheld magnifier similar to this one because I wanted to walk around in the Epic Citadel tech demo with a bluetooth controller, and it worked just fine. Be aware that looking around with a controller is a great way to get motion sick.

I'm using an LG G4
I have two headsets I switch between:
The BoboVR Z4 and the Freefly VR

The Freefly has a noticeably better FOV, but the center is out of focus (partly due to the curve of the G4) and other due to the design of the Freefly.

In contrast, the sharpness is leaps and bounds better on the Z4, it allows you to read text from a distance.

I have 3 PS eyes set up in a triangle position with the the single camera behind me and the two front cameras are about 3-4 feet in front of me on the walls to my left and right. All cameras are about 9ft high. The play area is great with about a 5 ft square of walk-able space (this is a limitation of my play area rather than the FOV of the cameras which is much wider)

I have my phone connected via a 10ft microUSB cable tethered and I have both cords wrapped around the vertical straps of both headsets so I can switch between them easily. The experience is incredibly smooth with no lag at all (I am using one of these cables: https://www.amazon.com/Anker-PowerLine-Premium-Motorola-Smartphones/dp/B019Q6F9F4/ref=sr_1_2?ie=UTF8&qid=1475102139&sr=8-2&keywords=anker+10ft+micro+usb and one of the 10 footers from this pack: https://www.amazon.com/Anker-5-Pack-PowerLine-Micro-USB/dp/B015XPL2JE/ref=sr_1_6?ie=UTF8&qid=1475102139&sr=8-6&keywords=anker+10ft+micro+usb

there does not seem to be any quality difference between the two.

My buddy just tried it and was pretty impressed :)

i hear the bobo VR Z4 is really good but a huge pain on your nose. i personally have 4 headsets and the best one for my phone which also has a 5.5" screen is the google cardboard 2.0 kit. the one i have is the MINKANAK headset. it has the perfect FOV i have ever seen and the lenses are really great too. it also has a headstrap, you can get it for $16 here http://www.amazon.com/Cardboard-MINKANAK-Virtual-Compatible-Smartphone/dp/B015GDVMIO?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00

It's the lens that is crappy. There's nothing that the phone can do to help it. It's just badly made.

I just bought a pair of the Smartdio 3D VR glasses (with a remote) from Amazon: http://amzn.com/B01B5R8CWY It was over $30 for me, but looks like it's on sale at that link for $26. They are the best I've seen so far. Not totally great, as the lenses are still kind of crappy, but with some fiddling (these goggles allow fiddling!) they are good enough for me. The headset is reasonably comfortable, and well padded on the face part, though heavy. There's a bit of light seepage, but not much (and there's a glare shield that I haven't tried yet). There's no button, but the remote should help with that. And it fits any size phone. And glasses will totally fit inside if you need them for close-up vision.

Oh, and there are no headphones on this. The sound is fine with just the speakers, as far as I'm concerned.

i just got a BOBO v4 clone (virtoba X5 elite - identical model but without headphones for half the price $25 on amazon) and it's leaps better than my old shitty cardboard 2 which was like 15 bucks to begin with


cardboard is heavily moddable but it's just not sturdy enough, it will stain easily from sweat, it doesnt cover your whole face and lets too much light in to be engrossing, the colors will fade wherever your face sits, and the lenses will shift around and become scratched to shit by your eye lashes


it's probably the best you're going to get until you get to an gearvr/oculus/vive. This is coming from somebody who has tested both the oculus and vive.

I really can't figure out how you could make it better (maybe better/bigger lenses, better button) without going into gear VR territory where either you get one built specifically for your phone or like an oculus/vive where it's got electronics inside

Just keep in mind the FOV/experience depends a LOT on your phone. I have a massive Nexus 6 but still can't get the advertised 120 degree FOV - but even still, i prefer more of the "scuba mask" effect since it feels more real.

Nexus 5x here, that headset is the same exact one I bought only with a different branding and a higher price. Overall it's a great headset with adjustable lenses and a head strap, mine came with a screen cleaner as well. It's fairly comfortable but does press on your nose a bit. Only complaints is that you have to take the headset off to adjust the lenses, and that theres no button for you to click. I purchased a ps4 controller which takes a bit of fiddling to connect but works great with all the games I've tried that have controller support. However there are some apps that don't have controller support and require a 'tap', so a cheap bluetooth controller might come in handy, i purchased one thinking it would work for games but aside from using it to simulate a tap it's actually pretty laggy(why i got the ps4 controller).

Here's a link to the headset($24.99): https://www.amazon.com/dp/B01C5IXFI8/ref=cm_sw_r_cp_apa_AvI4xbPAHN26G

And a link to the controller i bought: https://www.amazon.com/dp/B01ELDVFVY/ref=cm_sw_r_cp_apa_qDI4xbVWFG02D

I'm on my phone so sorry for shitty formatting, hope this helps.

EDIT: Not sure how big an S5 is but this headset will benefit from a larger screen, almost made me wish I got a 6p instead.

How about LeNest? To me it appears significantly better and more feature rich than any you mentioned, and it costs $30. Some discussion here.

I got one the other day (branded Pasonomi). I would recommend it. I'll put a review up soon. It's perfect except that the phone cradle is waaaayyyyy too big for my little Moto X, so I have to position the phone manually every time (could be easily fixed). Also there's some chromatic aberration. But it's very minor and really the least of my problems. (Frame rate and resolution are the biggest, mostly because of my current phone.) I'd like to see thorough reviews of the optics on a lot of these, since I bet chromatic aberrations and spherical aberration are quite common.

Edit amazon

I've been looking for one for a long time. I got the iPega controller (http://www.amazon.com/Wireless-Bluetooth-Controller-iPhone-Samsung/dp/B00GNXMXA8) which has iPhone 5s right in the title, but could not get it to work. It was supposed to support the "iCade" mode, but I couldn't get it working even with the non-VR games that were supposed to support iCade.

If anyone has a controller that works, I'd love to hear about it!

I hadn't seen this one yet, but they're pretty much all the same, except

• there is a version without headphones, so far only seen as "Virtoba X5 Elite" (not on Amazon)
  
• the newer batches have a "springy" headphones cable, looks very convenient
  
  The first part is obvious from the pictures, but I'm honestly not sure how you'd determine whether the one you're going to buy comes with the latter, unless you knew it from someone who's bought that specific item, I guess.
  
  About $40 may be the cheapest you can get a BoboVR or rebranded headset on Amazon.com, although I have a vague recollection of someone posting one for $36, but it might have been on GeekBuying or similar. I recommend paying the small premium and getting it on Amazon Prime instead. Your link doesn't look to be with Prime.
  
  Edit: I've just seen this which, for $38, seems to be the cheapest (not by much, but eh) on Amazon.com.

Cardboard is great if you are brand new to VR. But once you see how it works, I recommend upgrading to something like a Bobo Z4 headset or one that has head straps on it.

I imagine Google will discontinue cardboard once Daydream is fully up and running.

Link to a Bobo Z4, but I'm sure there are better deals out there

http://www.amazon.com/dp/B01EUXVRL8

I have a G3, a slightly older version of this controller and the Bobo Z4. It's an AMAZING setup, given what it is. QVR (Quake VR) is one of the coolest things you can do with it, since it's a fully fledged actual game that you can play. Don't waste your time with those piddly small controllers. They are all pretty much garbage.

I feel like I recommend this one too much but I really like the one I have. http://www.amazon.com/gp/product/B011EG5HJ2/ref=s9_hps_bw_g21_i6

There aren't any magnets. When you press the button it pushes on the screen with a stylus tip lol.

This one? It has a great field of view https://www.amazon.com/Virtoba-X5-Elite-Headset-Smartphones/dp/B01H35AU3G/ref=sr_1_1?ie=UTF8&qid=1484252061&sr=8-1&keywords=virtoba+x5+elite
And is one of the best mobile vr headsets available.

https://www.amazon.com/Pasonomi-Glasses-Virtual-Reality-Smartphone/dp/B01C5IXFI8/ref=sr_1_1?s=electronics&ie=UTF8&qid=1469631674&sr=1-1&keywords=pasonomi

I bought this one. It's pretty comfortable on my head and fits my Nexus 6P with case very comfortably.

From what I have read on this reddit, your best bet is probably a BoboVR z4/Virtoba x5/(insert clone here) which is around $40 on Amazon, as it will support phones with screens up to 6 inches.

It includes a capacitive button for Cardboard apps, but you will still need a controller for other apps that require one. I picked up one of these for $10 on sale ($15 now) and it works pretty well... https://www.amazon.com/gp/product/B01EO5QPN2/

Churuntek

Tho the link to the exact one I purchased is currently unavailable. I looked up his name followed by bobo vr and found a model with headphones and also a model without headphones.

Owl BOBOVR Z4 with HEAD STRAP AND HEADPHONES - High quality Google Cardboard VR Headset for 4.7-6 inch smartphones iPhone, Samsung Galaxy https://www.amazon.com/dp/B01EUXVRL8/ref=cm_sw_r_cp_api_vkDkzb08RCGNT

This link looks the same as the one I got. Hope that helps.. I'm unsure what you mean by being fake, but mine works perfectly fine.

Just get one that's a good price that comes with a headstrap. If you have amazon prime, get it there so you can get free 2 day shipping.

edit: This is the one I have. I do recommend getting a black one, I've heard that lighter colors can sometimes be distracting.

iOS is pretty limiting when it comes to Cardboard.

Controllers generally don't work, specifically there's nothing that would emulate the screen tap you'd need for YouTube, Street View, etc. The items that work for that on Android are mice, which Android supports natively and iOS does not. If you have an iPhone app that supports a controller, check with that app developer to see which controllers are tested and known to work.

The viewers I know of with buttons that work out of the box on iPhones are the ViewMaster (small lenses, not really recommended), I am Cardbord DSCVR (good for travel, no head straps), and the official design Cardboard v2.

I've seen one instance of a guy who got a BoboVR Z4's button to work with an iPhone by taping an additional area of foil to it.

The BoboVR Z4 is the more or less default recommendation — large lenses, wide FOV, built-in button, head straps, adjustable IPD, adjustable focus. There are versions with and without headphones, without being cheaper. It's somewhat heavy (most plastic viewers are) and the comfort isn't amazing (depends on face shape).

VR Viewers seem to always have a lot of rebrands, I've seen the BoboVR Z4 sold as the Virtoba X5, AFUNTA, and Uniify UV003. Even the non-shill Amazon reviews are generally worthless as most reviewers haven't tried more than one viewer.

Edited to add: link to a Virtoba Z4-clone for $20. If you're willing to mess around trying to get the button to work, that's probably your best option.

I have an iPod Touch 6th gen that I used for building and testing a VR app for a client. It is usable, but not ideal. (I'd say /u/amb9800 is a little harsh is saying "it's not worth trying".)

The HMD options are limited. Most will create gaps on the side, because they expect 5"+ phones. In my case I used it with a View Master VR headset with the iPod. (note: I have not tried the Deluxe edition). I've found it works the best, because it was originally designed with kids in mind.

If you just want to start out, using your iPhone, just grab the View Master VR. If you then end up wanting a better VR experience you can grab a refurbished phone, or upgrade your phone, and a higher end headset.

Even better deal through Amazon warehouse deals ;-) http://www.amazon.com/gp/offer-listing/B011EG5HJ2/ref=dp_olp_used?ie=UTF8&condition=used

Would anyone recommend something like these?
http://www.amazon.com/dp/B015XO1X5I
http://www.amazon.com/dp/B00U7MTPD4

The official cardboard lenses are 30mm biconvex lenses with a focal length of 45mm. If you cant see the edges of the screen (I cant) you could swap larger lenses with the same focal length to get a better field of view.

Maybe these would work? A cardboard shim might be needed since the focal length is 50mm.

http://www.amazon.com/gp/product/B00EPQ9SO4/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

Try browsing amazon. Here's one that I've had my eyes on that seems very decent for a first (or second) headset. It has a capacitive touch button and an nfc button. I don't own it myself, but it seems very good.

this would be better, you want a minimum of 34mm diameter. Longer focal length shows more of the screen.

http://www.amazon.com/Ajax-Scientific-Double-Convex-Bi-Convex-Spherical/dp/B00EPQ9SO4/ref=pd_sim_147_5?ie=UTF8&dpID=31fQ4P7mxYL&dpSrc=sims&preST=_AC_UL320_SR240%2C320_&refRID=0AQNKQJ6H2VY6X2S23W1

Dont think so, this was recommended though so I planned on getting it as well.

I'm rather impressed by your home-made cardboard rig, actually!

New to this whole VR thing here, having just been surprised with a [Viewmaster VR] (http://www.amazon.com/View-Master-Virtual-Reality-Starter-Pack/dp/B011EG5HJ2) starter for X-mas.
What is the rig you mentioned in the video? The ViewMaster is made for kids, and supremely "entry level" with it's lack of headstrap, but similar ones with headstraps are available for around the same price point ...
Edit: spacing

Just ordered https://www.amazon.com/dp/B00U7MTPD4/ref=cm_sw_r_other_awd_ejfNwbGZABAWG

Reviews for that model are good. Adjustable focal point. Magnet, foam padding, strap. $25.

Fits my Nexus 6p

Im also considering this one https://www.amazon.com/gp/product/B01H35AU3G/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=ALTVS0Q5KJ7M3
Which one do you guys recommend?

Is this a rebranded one? http://www.amazon.com/gp/product/B01B5R8CWY

Looks just like it, and it has prime so it will take 2 days instead of a month :P

http://www.amazon.com/View-Master-Virtual-Reality-Starter-Pack/dp/B011EG5HJ2/

I've ordered two of these. They offer a big step up from units that are actually made of cardboard. The mechanism that holds the phone is really well made.

UPDATE: looking at these glasses now: https://www.amazon.com/Pasonomi-Glasses-Virtual-Reality-Smartphone/dp/B01C5IXFI8/ref=zg_bs_14775002011_20
wondering if they would work well with 5c

I use this and it works fine with my iPhone 6:
http://www.amazon.com/gp/product/B018G1CJ3U?psc=1&redirect=true&ref_=oh_aui_detailpage_o04_s00

http://www.amazon.com/dp/B01B5R8CWY is this the same? It looks like the ones you linked, but has the Smartdio 3D brand name. Was looking for one with a controller (I don't have one personally).

Here is the desktop version of your link

http://www.amazon.fr/View-Master-Virtual-Reality-Starter-Pack/dp/B011EG5HJ2
is it the same product?

You can get a View-Master for $25. Much higher quality than any Cardboard that is actually made out of cardboard. No head-strap though (although you might be able to mod one on).

Also the magnet works with the magnetometer (ie compass), not NFC. And Cardboard V2 doesn't use the magnet, instead it uses a lever to tap on the screen.

$13 viewfinder

btw amazon is having crazy sale right now alot of there VR headsets are on sale.

I'm using a 5.2" screen but I just received a Viewmaster VR that works well with my Nexus 5x. I have only had a little while to check it out but for $20, I can't see any problems with that at that price point. I believe it works with most screens between 5" and 6" and mine came with an adapter for the iPhone 5. I looked at reviews and it seems the negative ratings are related to the Viewmaster apps and experience packs that come with it. I had no intention to use those so I can only recommend based on the cardboard experience which is decent so far.
