GEEKRIA 2.5mm 4-Pole Balanced Male to 3.5mm 4-Pole Balanced Female Headphones Adapter, for Balanced 2.5mm Output Devices, Aluminum Alloy Audio Converter, Gold Plated

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!

Great product worked seamlessly and sound quality didn't suffer.

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.

Works great Thanks

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.

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

Cumple con lo que se necesita

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

Goood well built product with good faux leather bag for protection ton and unit works well so far.

So had a balanced cable with 2.5mm connector and I recently purchased an IFI Zen Dac V2 and Zen Can headphone amp which both units a 4.4mm output so rather then buying a new balanced cable I decided to give this a go and it works fine. Have my Sennheiser HD600 running off the balance cable with the adaptor and it sounds great. Adaptor has a good secure fit on both sides no interference or left or right channel drops. So I highly recommend this adaptor.

works like it should

Non gli trovo un difetto, addirittura eccessivo l'astuccio in simil pelle.

Poor fit. only one channel works but if you turn 2.5mm in the adapter sometimes you get it to work but if you move slightly it just stop working again. Tried with 4 different headphone/ Cable.
