Long time lurker and I've found lots of good info here over the years, thought I'd try and give at least a little back.
I received my ivory Momentum Wireless today. They are pretty gorgeous, but you all know that.
I've been doing some random testing here and there as I've been spooked by all the talk of issues on this thread.
I've tried bluetooth on my laptop (retina macbook pro), my desktop (hackintosh) and my iPhone 6.
All of these run a mix of iTunes, Spotify (hi quality settings) and Tidal.
On both computers if I get more than about 10 foot away I start to get some drops and connection issues. However, I've never had my bluetooth connection be much better than that with all my wireless equipment. I have similar issues with my Jambox and Logitechs with bluetooth. They all don't do well at range, however, they are all older BT implementations as well.
My phone I get a bit better as long as there are no walls in the way. I can be all over my spare room (about 30x16 with desk in the middle lengthwise) with a decent connection, maybe a pop here and there if I'm moving a lot.
Now, my use case works for the Momentums since I rarely don't have my phone in my pocket (just hate dealing with the cable) and when I'm using my computer I just want to be able to move around without a cable getting hung or catching me when I'm moving to the makerbot or printer.
I have not testing them outside yet, but can report back as soon as I do.
The cabled connection is stellar and sounds very similar to my Momentum v.1s I do feel like the bass is a little more forward on v.2s, but overall very similar sound signatures. The USB connection also works great and seems to have more volume.
I'm so, so, so, so, so, so much friggin' happier with the ear cup size than I was with my V.1s and quite honestly it's the biggest reason for my purchase. However, they are just big enough. They definitely didn't go overboard on the resize. I could have taken another couple mm. ha.
I've also been flying a lot for work and I'm hoping to be able to take these with me (since they fold) and use the noise canceling.
A few folks have asked for some photos on the head for size reference, so I'm adding those as well.
Keep in mind two things:
1. My head is gigantic
2. I'm not a handsome man
If needed I could bring my v.1s home tomorrow and take comparison photos for size.
Thanks everyone, and I hope this helps!
Edit: Appears I can't add photos yet, so adding a dropbox link –
