The blue tooth connectivity is flawless. So, I threw it in my bag for a trip. If the WH is a 10, then the WF earbud IMO was a high 8. The Hi-Fi Stereo sound produced by these earbuds is Excellent and unmatched by anything else on the consumer market. Coats end up on top of each other. I love Skechers. Im not sure why the difference. You can dress them up or down which I love! Well worth the price in my opinion. Sound feels exactly like as it is hearing from a tweeter.
