NOWBOTUCH 2.5mm Male to 3.5mm Female Adapter(2 Pack), 3.5mm Female to 2.5mm Male Audio Adapter Converter Headphone Earphone Headset 2.5mm to 3.5mm 3 Ring Jack Stereo or Mono (2.5Male to 3.5Female)

These adapters were bought to enable me to use an existing balanced cable with my quad era 1 phones. The cable has 2.5mm jacks at the headphone end The phones are 3.5mm so the adapters were needed for compatibility.Unfortunately the audio is intermittent and non existent if I move my head when the phones are on .A great pity as they are well made and good value. it was the second set ai have tried....I can’t be bothered to return them again.

I have Sennheiser 6XXs. On my dac/amp there is 2.5 mm and a 3.5mm. Without the adapter it sounded amazing as usual. One of the best headphones for audio junkeys. With the adapter plugged into the 2.5mm (which supports balanced listening for headphones with duo wires in each headphone cup so technically better then the 3.5mm), It instantly sounded much MUCH worse. It was choppy and tones of static.In conclusion. spend more and get a better adapter. Don't buy these they will make your headphones or earphones sound 10x worse.

My microphone will not work with these adapters... Other party cannot hear me, additionally all I hear is a constant high pitched screech.Use: connecting wired xbox 360 headset (2.5mm) to a 3.5mm jack on xbox one (same issue when plugged directly into controller and via stereo headset adapter)Will return for refund.

Nothing to dislike . Two high quality adapters .I use them on my AKG headphones . Brilliant !

These arrived within 24 hours. Exactly as described. Seem to work very well, but I will not be using properly until I get some equipment in time.
