Geekria 3.5mm (1/8") Stereo Male to 2.5mm Balanced Female Headphone Plug Adapter, Converts Audio Plug Compatible Player Amplifier Etc.

UPDATE: I actually wasn't inserting the jack (2.5mm) deep enough into the adapter. The last bit takes more force than what I was used to. Obviously for TRRS there are multiple contact points, like a lock keyway. The 2nd to last pin is deceptively difficult, and feels like you are bottoming out. But not tight enough to really retain the plug. You have to thrust for all your worth to get to the 4th and final contact. Do that and this adapter is actually tighter than any device (DAP, AMP, what have you) jack I have had the pleasure of inserting. Therefore your cable and the adapter essentially form a single unit. It's great. And only $10.i have other geekria products and they are all great so that brand trust led me to buy this adapter. well i don't know about you but i like a tight fit. the 2.5mm female port doesn't secure the jack too well. i mean there's a click and some pressure, but it takes only a light touch to slip out (to the next detent). this will probably result in pops and squeals which you probably wouldn't enjoy. but who am i to judge your proclivities? for $10 i won't bother to return it but i will find an alternative. otherwise it's a well finished metal adapter which seems high quality.

Works like it should. I needed a new cable for my Massdrop HD58X headphones so I got the balanced cable that Drop sells. This adapter allows me to use it on a standard 3.5mm jack. I only got the balanced cable because i like the ~1.2 meter length better than the 3 meter cable I could find.

Fits great, light weight, self explanatory. I can't speak on if it works well cause the device I was buying the adapter for doesn't work. I'll have it handy thou incase I ever need one to test devices again. Nice sturdy materials used.

Works for Fidelio X3 with the 2.5mm balanced cable it came with

I have tried two of these adapters, the 2.5 to 3 and the 2.5 to 4, each is not worth it. The build is fine and they are sturdy but on each there is sound artifacts. You get a channel imbalance and static.The plus side is the came with some really nice flux leather carrying pouches. These are really nice for carrying iem's a good size 3 inch wide by 4 inch long drawstring pouch.I think they would be better off selling the poches and throwing in the adapters for free..

I first purchased the 4.4mm to 2.5mm adapter to adapt my 2.5mm headphones cable to the IFI Hip Dac. Then I realized how useful the 3.5mm adapter would be so I ordered this adapter. When it arrived I was disappointed that it would sometimes cut out. The must have just been something a little off on that adapter. Instead of starting a return I emailed Geekria. They responded that same day quickly and shipped a replacement. The new adapter arrived today and it works great! These are high quality adapters with awesome customer service to back them up. The packaging is crazy nice too!

Solidly built, but if wiggled there is play where the 2.5mm jack enters. This causes audio to cut out.I thought it might be the 2.5mm jack, so I tried a few from a few different manufacturers-- same result.No effect if the jack is not disturbed.

i didnt had high hopes as i have balanced hifimans. still gave it a shot and it worked.
