Hi. I'm about to replace a Logitech USB headset that I bought for my PC back in the day. They've done me good service, but are falling apart now. They were comfy, on-ear, with a good volume and mute control inline and a boom mic. My problem is, I am struggling to find headsets with USB connectors. Most seem to be gaming headsets these days, with 3.5mm audio jacks. And my MBP (15" retina 2014) only has a "headphone" jack, with no connector for mic. Or, is that just the way it's labelled? Is it like the iPhone - single jack that can handle microphone as well? The specs for the MBP that I can find aren't clear (to me, at any rate). What would anyone recommend. Mid-priced, robust - the things get carted around in my laptop case. Or should I just go for wireless? If it helps, I mostly (but not exclusively, so I still need stereo) use them for Skype - but for long calls, so they need to be comfy - and I would also possibly want to connect them to the Xbox. Thanks!
