I was skeptical, I have purchased some bluetooth wireless headphones recently for triple what these cost me and had nothing but problems with them but I thought it was worth the risk for less than $30. This thing is way too flimsy. I start playing my music and am immediately shocked to hear that the sound quality that Ive come to love on the M50Xs had been horribly degraded. I usually buy the pink/black Nike flip flop and love them. Mein nachfolgender Eindruck setzt auf dem Vergleich mit dem Bose und dem Beyerdynamic Amiron Wireless auf. The Sennheiser sounds great, but has some surprising cheap plasticky material thats surprising on a headset at that price point. Also please create a How to video for the product its will be useful for many of us! , you have adjuste volume of your phone also so you can get maximum volume. I was a little concerned if they could hold the weight of the bike, but since there were no mention of any issues I drilled the smallest possible holes I possibly could while still being able to hammer in the 4 anchors. WOULD NOT RECOMMEND!
