When worn hanging down, not great. When worn over-ear, not too bad.

I bought one of their MH750 joblots. I popped open a few and all were genuine.

Looks authentic to me. Something strange is going on if the audio quality on them is bad 🤔

You'll have to pop open one of the earphones and take a photo of the driver. If there are two solder dots on them, they're genuine.

I went ahead and MMCX-ified my MH750s. The little internal plastic nubbins that poke out from the back of the shells made soldering the wires onto the connectors trickier compared to the MH755. I got sloppy and melted one of the plastic shells by quite a bit, enough so that the shells wouldn't...

I got my first pair of the MH750 today and it has the Made In [space space space] China text on the tag. The nozzle filters have the small central white circle, different to the common fake ones that are large and white. The drivers have what appears to be solder dots but they're different to...

Genuine MH755s have black nozzle filters so yours is most likely a fake unfortunately.

Received some Koss drivers from Aliexpress, soldered them to an RHA MA650 cable with mic and remote, and snapped them onto a Parts Express headband. The total cost of the project was ~£20 and the results are pretty pleasing!

How does the MH750 with the bass reduction mod compare with the stock MH755? Are the frequency responses close to being similar?

I bought two sets of the SBH24's the other day. No tag on the earphones for me either. Imgur link

Did some digging in this thread and found the bass-reducing mod where you cover the internal vent hole and it pretty much did the trick. No driver transplant surgery needed!
