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

Plugged my headphones into this adapter and paired it with my Fiio dac/amp. Has run with no issues for the 2 years with solid audio quality. Looks sketchy though, for sure...

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.

Hace su función y resistente

Para los que dicen que no les funciono este solo funciona para cables balanceados si tú entrada no es balanceada no será compatible para los que no son balanceados puedes buscar otras opciones porque yo lo probé con dos cables balanceados y funciona en ambos y tiene buen ajuste no tuve cortes..

Boa qualidade
