Design is good. The bluetooth headset I was replacing was perfect until it started losing connection in the speaker (I was one of those with a wire connecting them together and the wire got frayed somehow). Willful T7 wireless earbuds are equipped with a sensitive enough high-sensitivity touch sensor that can detect every touch, I only need to move my fingertips to complete a series of operations such as play/pause music, receive/end calls etc. He really lost interest in watching this dvd movie half way though watching it. I tied it to the front and back roof racks (my side rack is only raised) and held very well for over 600km on the highway. If you?re on a budget and you own LOTS of shoes, these show boxes are perfection. Otherwise, I?m happy with my purchase and will continue to use it until I need a new case. Right now, theres construction going on in my house, and even though these headphones cant drown out things like bandsaws, they get loud enough for you to hear your music over everything else. I have 3 Feedback Sports Rakks but theyre going to be sold and replaced by these. I would highly recommend to buy if you are like me or you just want a new charger.
