Ive had several Sennheiser products over the years, and these are the best so far. I bought my first pair of this design Tevas 30 years ago and am elated that theyre still making them. I ordered this flip flops because I have an almost identical pair that I love and that I bought locally on sale at Sports Authority. They are comfortable and cozy without being too hot. See my photo. Bass actually thumps now; with the 2 you had to pretty much imagine where the bass lines were, because it certainly wasnt playing them. The seller?s service is also good, sending a lot of lossless music. I bought this product to put on my OC1 for the Naples Christmas Boat Parade. Once connected, you are set to go. Scholls exercise sandal, which I also swore by but somehow lost somewhere, back in time.
