FENTICO 3.5mm Male to 2.5mm Female/2.5mm Male to 3.5mm Female Stereo Audio Adapter Headset Converter Connector for Smartphones, Headphone, Mic, Tablets (2 Pack)

The product is very shoddily made, to very bad manufacturing tolerances. It needs to be plugged in at a very specific rotation else it will simply not work with the right channel. I would refuse to use this had I better alternatives but I do not so make do I must.

It came exactly as it was, amazon packaging deceived me as it wasn't great but once I opened the package, I didnt regret anything. It can attach a 3.5mm cable to a 2.5mm device and works almost perfectly after you rotate it a little bit to set it

It doesn't fit in seinheiser bluetooth headphones. Waste of time. Buy Aux cable instead.

2.5 to 3.5mm adapter is of good quality and fits my Bose headphones well

It is perfectly fitted on my dslr camera and working fine without distortion and fits well too

This product is only waste of money they diserve only zero stars

Lost Bose Ae2w aux cable and even the bluetooth control is on verge of death. So I wanted to purchase a wired cable to continue using Bose headphones. The wired cables are costly, hence thought of purchasing this 2.5mm to 3.5 mm adapter. There were many doubts in my mind about all tech stuffs, TRRS/TRS crap which is a bit tricky to understand. Still not sure if I could explain it, however I am posting pictures of the setup that worked really well for me. The bose bluetooth control panel seems to be a 2.5mm TRS jack, whereas this adapter has 2.5mm TRRS jack. I had an existing portronics aux cable 3.5mm (TRS) which is working well along with this adapter. The whole setup worked well for me, with no noticeable sound loss. Overall very satisfied with this product!

This is not suitable for Bose QC 25 head phones .. quality by look is good .. could not check audio quality as I could not use .. since there is no refund possible (only replacement) keeping it
