It arrived 6 days early and looks and works perfectly. SAMSUNG may make it good but AMAZON should not allow vendors do deliver Non-US warranted items with FULLFILLED BY AMAZON when we are known US customers shipping to our USA address. In the iPhone UI, the headphones identify themselves as BAETS (get it? like BEATS, but a cheap imitation piggybacking on the brand identity of a larger company?) Plus, the iOS device doesnt recognize them automatically, meaning you have to fumble with the audio selection choices on your phone each and every time you receive a phone call. Se apilan bastante bien y se sienten firmes y resistentes. I bought me already a second pair. Arrived as described, amazing quality for phone calls, using it for my buisness is saving me a lot of time :) thanks The sound is amazing . I recommend it highly and I look forward to wearing it as my symbol of faith. I love chacos but these started fraying at the heel strap within a month. My devices (2nd gen pods, 4th gen watch and XR) are normally at least at 25% when I place them on and within a 4-5 hour sleep I wake to them being fully charged.
