I decided to get the Backbeat Pros due to concerns over the glue on the M2BTs. So far I have mixed feelings on them. In terms of features and also the sound quality, I love them. But they just feel a little heavy and uncomfortable so far. I also get the same cutouts that I got on the VModa CFW in the same areas, so I guess this was not an issue specific to the CFW.
Going to try these out a little longer but might exchange them for M2BT or CFW again if I cant get passed the comfort issue. Also going to give up on bluetooth mode for my commute and use wired mode for that, to avoid the cutouts (but I still want the bluetooth to use at my work desk and at home).
Are the M2BT good in wired mode? Thanks for all the advice so far.
That's what I'm afraid of - I should be getting my repaired Momentum 2 back today and I don't know whether Sennheiser fixed anything. Spending the last week with wired IEMs shows me why I hate using wires. Even when I would run the wire under my shirt, it still managed to feel uncomfortable. For my commute, the cord has gotten tangled up in someone or something.
With summer coming, IEMs make a little more sense, so maybe I need to look for active BT IEMs. But then it's another gamble whether or not they work well with my phone and outdoor environments. And I know the sound won't be as full as wearing an over-ear pair.
