This is on behalf of a friend. He's recently bought a Sennheiser PXC 550 and is very happy with it, however the mic quality when connected to his PC is horrible. When paired with his phone he says the quality is fine.

Anyone else experienced this?

PXC can be connected in 3 different ways:

1. Wireless via BT
2. Analog via 3.5mm cable or similar
3. Digital via USB

I guess we are only talking about bluetooth on both the PC and phone. If so, the issue is most likely on the BT-card/dongle of the PC.

But we can't really help that much without knowing the phone model and PC's BT-card model. On top of that, some BT-dongles can even use different BT-stacks (drivers) that have different features (google Toshiba stack for example).

Ppl should learn to add more info to their posts when they ask for help...

Thanks for your reply!

Correct, we're talking about bluetooth only.

He's using a Galaxy S7.
He doesn't have a bluetooth card or dongle -- he's connecting to the bluetooth on his motherboard: Maximus VIII Hero Alpha.

I thought maybe the bluetooth was using a crappy channel for the mic audio but I don't know how to check that.

There's 2 different bluetooth "mics" the PC can see when using BT headsets/speakers with built in mics

one is for phone calls, really low sampling rate (22KHz I believe?) which sounds like a 90s telephone
one is for everything else, normal sampling rate (44.1KHz-48KHz) which sounds like a normal mic

You can view this by going into the sound control panel. Make sure he sets default the one that doesn't sound like its from the 90s

He might need to disconnect and reconnect once doing this, since using that mic usually sets the headphones into potato mode. recommend disabling it.

Ideally he'd want to use Wired to skip the bluetooth kerfuffle, but this should help


---EDIT

**** I just necro'd a thread hard. My bad. hopefully this helps someone

I think you can connect it as a 'headset' or as 'headphones' in windows 10, the headset one gives really low quality audio and voice.
