Honestly, the Sony MDR-1000x is the best unit I tried, in just about every category. Otherwise it is wonderful and would completely recommend. and I really love my SONY MDR-V900/V600s, but regardless of price, these are GREAT headphones. I wear them with summer dresses and shorts/capris and even skinny jeans! So excited to get these I had to try on right away. You dont have to be a cyclist to enjoy this book either. cumple con las espectativas this item comes with both sizes of lock pins, one lock and 2 keys. It worked for a good while but on a recent ride the computer was where it was supposed to be, a bit later not. Otherwise, I switch the headphones off for about 10 minutes, and when I try them again, the crackling has gone.
