Sennheiser Momentum True Wireless 2 - worst in-ear headphones I've ever had the misfortune to use - avoid at all costs!
I've owned and tortured myself with these Sennheiser Momentum 2 in-ear headphones for 2 months and am now certain that they are definitively the worst in-ear headphones I've ever had the misfortune to use. ANC doesn't work - surrounding noise floods into your ears as if you had selected transparent hearing on any other half decent in-ear headphones. It's impossible to use them to take calls in even light wind conditions because the caller on the other end just gets wind noise - as do you as well. In case you're wondering whether I am using the right fit adapters, I tried all of them and ended up with the largest version - anything else just exacerbated all of the problems I've described above. I really regret buying the Sennheiser Momentum 2 and they are not worth considering at any price - even if you are offered them for free, do your ears a service and decline the offer.
