Question 1

Can these headphones connect to 2 devices at the same time just like the Bose QC35's?

Accepted Answer

Yes. The headphones can be paired to 2 active devices at the same time. (It can remember up to 8 devices in memory). My headphones automatically switch between laptop high fidelity audio vs iPhone depending on which devices is outputting sound. (When pairing on with PC make sure to pair the stereo headset device for high fidelity audio)

Question 2

Whats the difference between these momentum 2.0 bluetooth?  same price point. why choose one over the other?

Accepted Answer

TL;DR - I'm selling my HD1s (Momentum) and going back to PXC 550. I had a much older PXC 550 model which I LOVED and travelled with for several years. I needed to replace them so I opted for the HD1, which is the precursor to the Momentum. I wanted to love these headphones - they look beautiful, they sound beautiful, they are awesome for both calls and music - BUT they are SO UNCOMFORTABLE. I cannot wear them for more than maybe 30 minutes at a time before my ears are killing me. They don't actually go around my ear, they are too small so they sit on top a bit, which squishes my ear against my head. This would be OK if they were actually on-ear headphones, but they're not, they're very heavy and tight against your head. If you are looking for comfort, the PXC 550s are the way to go without compromising the sound quality.

Question 3

Hello! how do you compare pxc 550 with mdr 1000x from sony???

Accepted Answer

I bought the 550 and returned it for the Sony 1000xm2.   The 550 has better noise isolation, but was really underwhelmed by the audio quality.  Both cancel out the white noise but the 550 seemed to block out voices much better, which may simply mean it has a better seal on my head.   But the audio quality was very inferior to my ears.  I own the Sony MDR-1A, and the 1000xm2 isn't quite as good as those wired cans, but they are a lot better than the 550's.  That coupled with the clunky app for the 550's made me switch.  The Sony isn't perfect, it still beeps at me randomly every so often and I haven't figured out how to make that stop.  It is only every 20 minutes or so, so I live with it.

Question 4

My ears are a bit smaller than an average adult and they fit me well.  If you have large ears, they will not work well
