Weight, comfort, build quality, the sound overall is amazing. I 100% agree with this approach. I started looking at reviews for the Sony SRSX55 and was encouraged by reviews that captured what I was looking for in a Bluetooth speaker. I work in a restaurant that serves ice cream and I have spilled hot fudge, ice cream, carmel, etc and even if I wasn?t able to wipe the shoes down until I got home the funk came off easy! I wouldnt buy another pair of these given my experience. They have sturdy construction and are very easy to use! The problem is that the doors naturally open ?left to right? and cannot be installed the opposite way. Great shape, great size, but difficult to get the product out! Just make sure to put them on correctly! The shoe itself is great.
