Please watch the video I quickly compare these to 4 other wireless headphones. You cannot beat this product for sound quality and loudness. These are my favorite brands now. I have used them for two solid weeks working out and running at least 6 times per week. The battery life is good on these and last just a few days. Only thing I might have noticed is not much warning on the low level battery. I have many sets of wireless headphones that I have been provided and now know what to recommend to everyone out there trying to buy cheap wireless headphones. Stay away from the $15-30 prices point. Go with the $30-60. I also have a pair of Platronic and these are much better because they provide just nearly the same quality but are much much louder. This pair is absolutely rock solid. Best pair I have ever owned. Pros - Comfortable fit and secure. Great Sound Quality Amazing High Sound level - Very Loud which is great for pumping Thicker rubber ear hooks Comes with multiples sized ear pieces Cons - Not as much warning for low level battery I received these for free in return for an honest review.
