I purchased these because I am not spending $200+ for ear buds . its well built. Id like it if the lead looked a bit more robust, maybe one with a woven cover? And thats why I dropped a star on the review. Have not used the microphone, and never intend to use it. Case is very flimsy. We needed this adapter to complete an installation, and it did exactly what it is supposed to do. Unfortunately, arm cannot be re-attached. As others have stated, the bass can be quite muddy at times. They are warm and comfy and look nicer than some of the other "winter" styles. I use these in the office primarily with the intended occasional bike ride at the weekends (still yet to try this).
