QC35 Boom Microphone with Mute Switch Compatible with Bose QuietComfort 35 II(QC35 II) & Quiet Comfort 35(QC35) Headphones, for PS4, PS5, Xbox One, 4ft

As advertised

The description barely mentions these working with the Bose 700s. It's clear that they're designed for this headset, but they sit on there just fine. I bought this because I was looking for a way to use my phone while on the freeway in my old noisy truck. All my other bluetooth dudes didn't pick up my voice enough...just like these. This mic sits right up near the mouth, and people can hear me just fine. Of course they need to be plugged in to your phone to work, which works great on my OnePlus 7pro with a USB C adapter. The active noise cancelling still works great while this is plugged in a well. Note that your headphones do need to be charged and turned on for them to work at all, even with this plugged in. Very happy with this purchase.

Microphone worked fine for a weak, but is loose fiitting. You need to angle it at a correct angle in order to even have decent audio. DO NOT BUY.

the fit is a bit tight. My old one clipped on somewhat easily. This new one takes some effort to snap in. If you intend to use the headphones with thed mic all the time, you shouldn't have an issue. I will be using the mic intermittently so putting it on and off is a bit worrisome. That was the only issue I found.

If you have that Bose QC and feel that connection if wirelessly to your PC is laggy, this is your answer. Outstanding clarity both in and out. Was on Jabra before, not bad but not great in noise cancellation. This though wow. I am sitting 4 feet from a 15000 BTU Air Conditioner and when I tell you I can't hear it, I cannot hear it. Nor can people on the other end. Bose 35 + this thing, at this price, no brainer
