If the XM4s were good for calls/facetime I'd've bought them by now. The XM3s were dire, according to reviews, and the XM4s aren't much better.He also did a voice recording comparison, which I haven't seen before. I was really surprised how bad the XM4 voice recording is, but for everything else they're comparable.
I then nearly bought the Bose 700s as they have brilliant call quality, but their firmware and app gets uniformly slagged off. Plus reviews say they don't sound great. So then I decided to slghtly compromise on call quality and audio and looked at the PX7s. I'm not a fan of touch controls, so the PX7s win out here with actual buttons. They're bulky, have a bad app with no EQ, and a high clamping force. The latter puts me off.
I would have dropped money on the Max's if they didn't involve compromises, but like the others, they have their faults. They're heavy, bulky, bad case, and some immediate reviews talk about connection issues even with Apple products, although I'm sure a firmware update will fix that.
My problem is that I can't decide which compromises to make and keep waiting for the perfect pair. I was hoping today was the day. But at least I'm $600 richer than I otherwise would have been
