I bought the Momentum 4 Overear for 250 CDN and am blown away by the sound these cans produce. If yo get some buy Geekria Silicon waterproof earpad cover to protect the electronics inside the earcup to short if you sweat profusely and repetitively in them. I also got the True wireless model along with the BTD 700 which is a usb-c dongle that bypasses completely the bluetooth stack and the AAC only apple implementation. It unlocks APT-x Lossless, Adaptive, and Auracast when used with the Momentum 4 True Wireless. It's coming July 2.
