Ive worn the replacement pair that Keen sent me for about two months and the sole of one of them is already coming off. There seems to be no rhyme or reason it happens. I just thought Id mention it in case something like that is important to you in deciding what kind of device to buy. But thats insignificant to anyone whose had soggy cushions on their ears listening to music. Ive only had the party box for a week now and we use it just about every day. All of our clothes, shoes, stroller, soaked. MicIve had people in Discord and now Twitch chat tell me my mic is incredible. They are stable in ears and sit well. Its pretty secure but Id like to have that double strap to be extra secure. GO UP A SIZE!
