Reddit mentions of Grado Mini Adaptor Cable - 1/4 Inch to 1/8 Inch Plug

I suggest getting a different 6.3mm to 3.5mm adapter, as the one that comes with the HD599 tends to put a lot of stress on the 3.5mm jack, as you may already have noticed. Something like this adapter from Sennheiser will work great:

The Grado adapter should work fine as well and is cheaper:

And there are other adapters like this one for Hosa which are cheaper still:

Or just use the shorter cable with a 3.5mm connector that comes with the HD599 if you can. Anyway, that's a great setup to get started on the hobby. Now you can feel free to never visit this sub again to save yourself some (ok, probably a lot of) money.

Use one of these instead of the solid adapter if you need (I have the 595's and still haven't done a detachable cable mod because this thing works so well).

> Do you have them?

I have them and their big brother, the HD 800.

> Do they induce headaches because of the band?

They are widely considered one of the most comfortable lines of headphones on the market, and I certainly agree. They are made of study plastic and ultra-soft velour. They do not induce headaches or irritate my ears, and I consider myself vulnerable to these sorts of things.

> All I need to do is plug them into the headphone jack on any fitting device

The stock termination is 1/4'' TRS (big headphone jack), which may not fit in your computer or other source player. The HD 558 ships with a 1/4''-to-1/8'' converter, but many people find it bulky. I recommend this Grado adapter cable, Grado being a headphone company we all know and love.

> and it'll output 7.1 warranted it's available?

Don't worry about how many speakers you're supposed to be hearing. If you're a fan of surround sound, I guarantee any (well-mastered) recording will sound phenomenal to you through these cans. Sennheiser headphones are known and praised for this quality.

Very cool, thank you for the tips!

This is the grado adaptor you speak of yeah? http://www.amazon.com/gp/product/B001DK1ZVO?ie=UTF8&at=&force-full-site=1&ref_=aw_bottom_links

I like the extension to avoid stress on the inputs.

pretty sure that's the one I bought! http://www.amazon.com/Grado-Mini-Adaptor-Cable-Inch/dp/B001DK1ZVO/

Your O2 has 3.5mm input and headphone jacks. The stock cable on the HD 650 has connector of 6.3mm (also known as 1/4").

You should have a 6.3mm to 3.5mm adapter with the headphones, and if not, you'll need one to plug into the O2. Many recommend the Grado style adapter, like this one. Sennheiser also makes one.

Edit: Looks like you've already got an answer, and a cheaper price on that Sennheiser adapter also.

Ditto. They're cheap enough and the highest quality you can get without overspending.

Ah good point

Radio shack has this for a couple bucks http://www.amazon.com/gp/aw/d/B001DK1ZVO/ref=mp_s_a_1?qid=1368143673&sr=8-2&pi=SL75

But yeah that is kinda silly

Well, it depends on what you're playing from. I have the HD650 which is (imho) even better, but also more demanding. Does it sound it's best when driven from a decent amp? Hell yes. Does it still sound good when driven straight from my Macbook Pro, iPod Touch or Android phone? Sure! Not as well as being well driven by an amp, but more than good enough for me to enjoy.

The HD598 is easier to drive than the HD650. You should be fine in the initial going without an amp or dac unless your source is total crap. One thing is that the cable on the HD598 will have a 1/4" plug at the end and probably some 1/4" to 1/8" step down adapter. Quite possibly, it'll be one of those that'll put torque on the jack which I'm not too fond of, so plan to spend an extra $15 or so on a better one like this one from Grado

They are pretty efficient, so anything decent should do. I think a Schiit Magni 2 fed from your onboard would be your best choice, but something like a Schiit Fulla 2 or Fiio E10K would also do fine. You might even be fine running it straight out of your onboard sound. If you do decide to run it out of something with a 3.5mm jack, get an adapter like this to ensure that an accidental yank of the cable does not break anything. Solid adapters like this are a really bad idea.

I would reach out to Sennhesier, maybe your adapter is defective. I've owned a range of their headphones and they have always been tight-fitting.

Otherwise, the Grado adapters are well regarded - https://www.amazon.com/Grado-Mini-Adaptor/dp/B001DK1ZVO .

Yeah this one https://www.amazon.com/Grado-Mini-Adaptor/dp/B001DK1ZVO/ref=sr_1_11?ie=UTF8&qid=1494418630&sr=8-11&keywords=6.3mm++adapter

I've just bought this from Grado to use with Mojo

Very nice, sturdy adapter, well worth the price (totally ~$22)!

Cable for less stress, I use this one here

I can help with the kid's keyboard part. This is pretty bootleg, but it'll work. I'm not the best at explaining things, if you need clarification, let me know.

• Unscrew and open up the keyboard
  
• Clip the two wires that attach to the speaker
  
• Strip the ends of the aforementioned two wires
  
• Find any mono audio cable (you could use a guitar patch cable, a single RCA cable, etc. Just make sure you have the proper adapters to plug it into the line-in on your sound card)
  
• Strip one end of the audio cable (it should expose two sets of wire)
  
• This part takes a little trial and error (and is the tricky part to explain): Wrap the ends of the wire that used to be hooked up to the speaker to the ends of the wire on the audio cable... Keep the wire groups separate.
  
• Test and see if you're getting audio out of it by hooking it up to an amp or your computer. If no, swap the connections (unwrap the wires and wrap them with the other ones)
  
• When everything works, get some electrical tape and cover your newly created connections.
  
• You may want to drill a small hole to feed your newly created output cable through, just to keep everything looking pretty.
  
• Put yer keyboard back together.
  
  If you can get something like this you can mount the female portion to the keyboard and create a more standard output (instead of being limited by the length of your created cable). edit: You can remove the speaker and use that newly reclaimed room to mount the output.
  
  Hope this helps.

Hum Maybe a Micca Origen+, another real nice piece of gear but alas only available in the US, since I live in France I've had to look elsewhere.
Or else just get an adapter but mind to get one with a chord as otherwise you'll be putting to much weight on the 1/8 mm input.
something like this: https://www.amazon.com/Grado-Mini-Adaptor/dp/B001DK1ZVO/ref=sr_1_26?s=electronics&ie=UTF8&qid=1510911707&sr=1-26&keywords=headphone+adapter+1%2F4+to+1%2F8

It's also a stronger lever. That 1/8" jack will get worse and worse eventually becoming unusable without jimmying it just right. The kind of thing that will drive you crazy.


I've been using the same adapter from Grado for 15 years.
