GEEKRIA 4.4mm to 3.5mm Balanced Headphones Adapter Converter for 3.5mm 4-Pole Cable to 4.4mm Player Device, Durable Aluminum Alloy Conversion Audio Plug, Gold Plated

I got this to connect my Sennheiser HD58X to my Yamaha RX-V800 receiver and it works flawlessly. I have a 2.5mm balance jack so I needed exactly this to make it work. It's awesome and it has not white noise, so now I can listen to stuff without disturbing my sleeping wife. For the price is really good and comes with this lovely leather bag to save it. Seems pretty sturdy but we'll see with time.

Great product improved the sound in great way to my over the head earphones. Easy to connect to my iPhone and work perfectly

This is a great 4.4mm to 2.5mm balanced audio adapter. It works great and is of high quantity. I needed this to adapt my 2.5mm balanced cable of my Sennheiser HD-650 headphones to my dap. As a bonus, it came with a very nice pouch case that fits my Fiio JM21 dap perfectly. This is a great value at this price and the included case is just icing on the cake. Recommended highly!

I bought this to use on my Fosi Audio K7 to drive a pair of Audi Technica ATH-M50x and it works great. Snug fit and no issues at all.

It's important to understand this adapter simply allows you to connect a 3.5mm plug into a 4.4mm balanced socket, it doesn't convert any signals. I used this to connect headphones with a 3.5mm plug into a dongle with a 4.4mm balanced socket. All it does in this case is draw a little more power, because it makes the sound louder. There's no change to the sound quality. In order to receive a balanced signal from a socket, the headphones and cable itself have to be wired in a balanced configuration, otherwise the signal stays the same (unbalanced). Keep this stuff in mind to determine if you only need an adapter or you need to change the entire cable.

Good adapter. Working well so far.

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.

If you are thinking of buying this to plug regular headphones into an amplifier with a 4.4mm jack, don't. 4.4mm jacks and 3.5mm jacks don't fit for a very good reason - they are electrically incompatible. Most 3.5mm devices have a common ground while 4.4mm balanced jacks drive a differential signal. If you plug regular headphones into a balanced amp through this, here's what will happen: 1. You'll hear so-so sound quality with an annoying hissing noise 2. Your amplifier will get very, very hot because the negative lines of the differential output are dead shorted together 3. The amplifier power supply will shut down from overcurrent, or if it's cheaply made it will just start smoking
