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

It did the job I wanted perfectly, which was to connect my headphones with a 3.5 plug to a 4.4 ballanced socket.

Good solid adapter well made works a treat

I’ve given it 4 stars Only because it doesn’t work for my specific use case but that’s not really the fault of the connector. I’ve tried to use this to convert from balanced 4.4 to unbalanced headphones at 3.5mm. This was a gamble and I knew it. Although sound does come through the headphones, it’s heavily distorted. This is likely the fault of the Zen DAC and there was no literature that said this was feasible on this DAC. I took the risk. The build quality is fine and it’s worth what they are charging In my opinion based on the rarity of the 4.4mm connector so factoring additional cost of manufacture I think it’s fair. As long as you’re going from 4.4mm to 3.5mm balanced as advertised I think you will be fine but don’t try and use it to go from balanced to unbalanced headphones with it unless you’re happy to gamble the £8.

Good

This adapter is designed for balanced stereo signals, however, it works just as well for connecting headsets and earphones with the TRRS combi (combined headphone and microphone) jack if you don't want to use a traditional TRRS splitter and have the microphone end flapping around doing nothing. I've spent too long getting frustrated looking for an adapter that works correctly with combi TRRS jacks. Then I found this one. The other adapters seem to have lousy placing for the ground contact meaning it struggles to make a good connection with TRRS jacks, and you have to have the 3.5mm jack hanging out slightly which gives you a poor mechanical connection meaning your 3.5mm jack could potentially just fall out, or become misaligned again ruining the audio quality. Because this is expecting a 4 pole (TRRS) jack for the balanced signal, it has correctly positioned contacts allowing solid connection both electrically and mechanically. I think the seller should consider marketing this little adapter as being useful in this secondary usage. I would've probably found it quicker. The adapter is about the same size as most of my other 3.5mm to 1/4 inch jack adapters and has an all-metal construction, featuring gold-plated contacts. Jack insertion is a little tough but it's the same force required as pretty much all my other adapters. I just wish there was a Right angle version for compactness.

Excellent, just what I needed and looks good quality. Ordered Friday and delivered Saturday.

Excellent adapter, works exactly as advertised. Well made and good value for money.

Short review for GEEKRIA 4.4mm Male to 3.5mm Balanced Female Headphones Adapter. When using this adaptor it does not make a clean connection and if you touch it, it goes from getting output from both headphones to one or the other. Not an issue with the 3.5mm jack I'm plugging into the back of this adaptor as the headphones work fine when connected to an alternate 3.5mm port. Also, connecting 4.4mm headphones instead of using this adaptor work fine too. Complete waste of money but can't be bothered sending it back. Would NOT recommend.

Works perfectly!

Works just fine. I imagine some of the troubles others have had with similar items is that they're not four-pole (as needed for mic, left & right), but just three pole for stereo without a mic. Anyway, this works fine for 3.5mm cell phone headsets plugged into old cordless phone jacks of 2.5mm.

Excelente adaptador, porém, por causa dos impostos, deixa de ter um custo-benefício.

This is, so far, the best 4.4mm to 3.5mm conversion gadget I own. I have extensively used a few other 4.4-3.5 conversion wire, but this specific solid adapter delivers the best sound quality. Perhaps it's due to the lack of wire media that caused certain signal communication degradation. Highly recommended!

I bought this to use with the FIIO KA2 and would recommend it. I haven't encountered any issues with it. However, I noticed that one of my IEMs (KZ ZEX) is producing some kind of distortion. I suspect it's because of the cable from my IEM, as I don't have the same issues when using other IEMs (Salnote Zero and Shure SE215) or headphones (such as ATH-M50, Sony XM4, Steelseries Nova 7, Surface Headphone 2). So, if you experience any distortion, it could be due to your cable. One workaround is to use an AUX extension. I have a 10cm AUX extension that I use, and it eliminates the distortion for the IEM that I had issues with. However, what worked for me might be a different case for you, just keep that in mind.
