They are good while runing. Okey talkning on the phone.
These must be my 6th pair over the last 3 years or so. I find them great for sleeping in listening to white noise or an audio book etc. Though a few batteries haven‚Äôt lasted very long if accidentally left on charger for too long
Sound is great, but battery is too big. Microphon a little bit weak, Interlocutors report noise and whirrings, with good connection quality and/or whatsup calls
