Looking forward to your comparison!
So a few additional thoughts on the Jabra Elite 10s now that I had a few minutes to try them out. As an all-rounder, I think these are great if you don't care about codecs or the best ANC. They are very comfortable, good enough SQ for use when out and about, and so far so good for calls. I especially like the sidetone feature which makes taking calls very comfortable (apologies if the below seem a bit scattered or short-hand...have an almost 1 month old at home).
Sound - I need to play around with the EQ a bit but my initial reaction was that it has a very full sound and a nice wide soundstage. I need to tweak the bass and mids a bit as the bass was a bit overpowering for my personal tastes and it does sound a bit v shaped to me but they sound great so far. In comparison, the Samsung GB2P sounds very bass heavy and has a much narrower soundstage to my ears (note, I never really used the GB2P for music anyway). Based on the few minutes I have had to listen to them, I prefer the Elite 10s to the GB2P, even with my source being a Samsung Galaxy Fold 5 (i.e. AAC on Elite 10s vs. SSC on GB2P). For SQ, MTW3 still wins in my book. They just sound more natural to me while the Elite 10s still sound a bit processed (not really a fair fight since I have spent hours tweaking the EQ on my MTW3).
EQ - as noted above, I have not had time to EQ them to my sound preferences but they seem to EQ well and I think I will be able to tweak them to my liking. Can't hold a candle to the MTW3 Sound Personalization feature.
Calls - was able to try it out on a call. No complaints from the other end and the sidetone feature works really well. This was in a quiet room so no idea how it will perform outside but I am usually taking calls in my office anyway. I picked up the Elite 10s primarily for calls so I am happy with these. Has some nice features where it will pick up calls automatically (Samsung also has this) and has mic mute functionality, which is pretty cool.
ANC - have not had a chance to test it out outdoors but it seems the weakest of the three. Not bad but not the best. I don't think I will be traveling for a while anyway. However, as I was typing this, I noticed I could hear myself typing with the Elite 10s (I made sure I was on ANC mode). Hearthrough is adjustable and seems to work well. I like that I can cycle through ANC/Hearthrough/Off using a physical button. However, I did notice the sound changes significantly when enabling Hearthrough/ANC vs. Off on the Elite 10s. As I believe someone mentioned in an earlier post, the MTW3 does this very well and is pretty consistent when you switch between passthrough/ambient and ANC (I usually use anti-wind mode ont the MTW3)
Comfort - these are the most comfortable to me among the three (Elite 10, GB2P and MTW3). They really seem to disappear in my ears compared to the others.
Physical buttons - I forgot how much I missed physical buttons. Fully customizable and work well.
Take all the above with a grain of salt as they are my sleep-deprived opinions after less than an hour of listening (new toy syndrome is real in my opinion) but I am happy with these so far
EDIT: figured out how to save custom presets by pressing the + button next to Music Presets in the app. Knew there had to be a way.
