Yeah, you have to take them off with the case, unless you have the waterproof case from the Sport version. Sorry I didn't mention that. I agree, I too like the T5 II ANC better. I just got a response regarding the beeping issue I'm having with the MW08S.
"Thanks for reaching out, and for choosing Master & Dynamic. I am sorry to hear you are having issues, but I hope the below will help. The "beeping" people are hearing on the other end should be resolved with the latest firmware version - 4.4.4."
Of course they ran me through the typical process of resetting, blah blah, all the stuff I've already done. Nice they acknowledged there was an issue, sadly, I'm having that issue. Trying to get a replacement now...
