I suspect my BH-214 is a fake but this not 100% copy still works for skip back, skip forward, answer, pause, volume, and doubleclick answer for call last number dialed. The poser button and answer button are wired together so depressing the answer key in a bag will turn on and waste some battery though it will shut off after a bit of being not paired.
Normal 3.5mm audio jack and DIY single headphone made from sony hook over the ear phones or diy short headphone from my ripped Nokia wired headset.

I did something similar with a MEElectronics AF9-BK. Snagged the lipo out of a broken s9-hd pair i had, and went from 100ma to 180ma iirc. The device itself is tiny, 1.9 x 0.4 x 0.4 and something like 10g.

You couldn't stuff a bigger battery than a s9-hd 180ma lipo in it i think, its pretty tight after the mod. But, i went from 6hr battery life, to around 10 hours.

Build quality and sound quality is pretty decent, for the price. And i got it ~1/2 current retail on sale at newegg, so i'm pretty happy with the device. Only gripe is no charge/usage at the same time. I'd love to make a mini battery pack with a 500ma lipo and small 5v dc/dc converter to charge it on the go, but its still limited as far as taking 4-5hrs to charge from a full dead, and no playback during charging.

Still, if you can get it under $40, i'd say go for it.

And btw, if you do mod a new battery in, don't solder the lipo leads off the board. I was too yellow to get a soldering iron near those joints, considering one slip would be a dead short to an unprotected lipo. Just cut the leads one at a time, and then solder/heatshrink the leads from your s9-hd/whatever battery you use instead.
