Review: Great option for Sennheiser Hd558 / HD598 after modification - I use Sennheiser HD 558 and 598 Headphones at both my gaming computers. But between my 5 year old and 10 year old they are extremely hard on cables. After paying too much for special Sennheiser replacement cables, I decided I would take both sets apart, remove the locking mechanism and use a 2.5mm Male to 3.5mm female adapter so i could use standard headphone cables. Initially I bought some cheap china adapters. Was like $7 for a 2 pack, and while they were basically a drop in option they just didn't hold up over time, when i move my head audio cuts out on one side. So I was back to square 1 looking for a solution. I bought a couple different adapters including one of these, it seems much higher quality and is a much tighter fit. Unfortunately it's not a drop in option. Its slightly larger diameter. I had to remove the chrome bezel and used my soldering iron to melt the hole out a bit larger. It looks fine, and I'm hopeful that this will be a final solution. I really think it will be, the quality is much better than the previous adapter, and it fits both the headphones and cable much tighter. I went ahead and ordered a second adapter for the other HD558 headphones. I do not use the balance feature of the adapter, so i cannot comment on that. However I can say it doesn't hinder anything either. It works fine, I have stereo sound, and maybe it's placebo but i'm 90% sure this adapter made them sound better and louder.
Review: Works great. - No audible degradation in sound that I can tell. Build quality seems very good. Note: Product images on desertcart show EXACT pin out very clearly, unlike other brands where it ambiguous as to what you are buying. Good job, Geekria.

## Questions & Answers

**Q: I normally use 3.5mm - rca connect to my nw-zx300 so will it make differences if i move to the balanced output using the adaptor?**
A: I gather that the NW-ZX300 also has a 4,4mm balanced output. This Gerika adapter however has a serious fault: three poles are electrically shorted so it can only function as an unbalanced adapter (unless Gerika have fixed the problem). This can easily be verified with any multimeter. Obviously the balanced output requires four separate electrical connections to your headphone: two cables to each "ear". To enjoy the balanced output you obviously need headphones with a balanced cable (4 poles/wires). Do not connect unbalanced headphones to a balanced output. If you fulfil those requirements, you also need a true balanced 4.4mm to 3.5mm adapter such as the "Meijunter 4.4mm (Male) to 3.5mm (Female) Balanced Cable Plug Adapter for Sony PHA-2A/iBasso/Fiio/HiFiman Headphones, Replacement Metal Cord Plug Line Jack Connector" in amazon.com. This correctly passes 4 poles from the male plug to the female socket.

**Q: Would this work to get 2.5mm balanced output from my es100 dac, for HiFiman Sundara w/ 3.5mm jack?**
A: I believe the balanced outputs (on the DAC) are either 2.5mm or 4.4mm.
Most ALSO have a 3.5mm jack.
This adapter allows for use of standard 3.5mm headphones/ earbuds on 2.5mm outputs
Adapters are available in most configurations. I would get an adapter for 4.4mm or 2.5mm ONLY.
This particular adapter fits a 2.5mm output for 3.5mm audio connections.
They won't make your 3.5mm output balanced.

**Q: Is the cable 2.5 balanced male to 3.5 balanced female or 3.5 unbalanced female?**
A: This Geekria adapter is 2.5mm balanced male to 3.5mm balanced  female.

**Q: Does this convert the output to balanced audio?  Or just allow one to use balanced cables in a 3.5mm port?  Is there a balanced audio benefit?**
A: To convert 3.5 stereo to 2.5 balanced, you need your headphones to be balanced sound headphones. Balanced sound is the independent output of left and right sound sources, and stereo sound is the same decibel.

### ⭐⭐⭐⭐ Confirmed to be a True Balanced Adapter
*by T***E on March 7, 2019*

TL;DR - Okay, this is my apology to Geekria. You get 5 stars for making a good product, despite my concerns about longevity due to weight hanging off the 2.5mm jack. In previous versions of this review, I was sure this was not a true balanced adapter, based on wording of the above marketing materials. I actually physically disassembled this piece, and I could confirm visually, that not only does the male jack have 4 poles, but the female jack does as well, and they are all connected by separate leads. In conclusion, this is a real balanced adapter. If used properly, with 3.5mm 4-pole balanced-terminated headphones, it should not damage balanced amplifiers. My only other concerns to note here, is that the 2.5mm jack isn't very thick, and having seen 3.5mm jacks snap easy, putting the weight of a larger connector hanging off the 2.5mm jack worries me. However, I understand it's better, in theory, to solder the 2 connectors together with as little distance/wire between them as possible. **NOTE** - I want to briefly speak on "stereo-balanced adapters" here, and state that the main difference between differential and shared-ground designs, from a performance perspective in regards to headphone driving ability is more power. When using balanced speaker setups, balanced connections have a greater ability to reject common ground noise, or hum over longer cable runs, in studios. Headphones generally have such a short cable run, that unless something is very wrong with your setup, balanced should not solve any problem you're having specifically with the sound coming out of your headphones. However, amp circuits designed for fully differential wiring should not be used with shared ground terminated headphones/cables. People much smarter than me say that you will damage an amp by attempting to do so, it's only a matter of time. Therefore, regardless of the above, I highly recommend that you DO NOT attempt to run your 3-pole headphones balanced with this adapter. BUT, you should feel no worry running this with a fully differential/balanced-terminated pair of headphones.
