I walked over 40 miles in these during a visit to Italy. Conversations were easily heard and the mid / high separation is definitely better than what other BT speakers have. Son excelentes y muy comodos ademas, Thats to be expected for this price range though. with cracking noise during battery low, it should ideally be priced less than 2kBattery life is 90 percent to what it claims I had a pair of the other soulsfeng and they were just as good. I fell into my Skechers almost two years ago by accident. The ankle strap is very thin and causes discomfort because of the unequal weight distribution of the thin strap and heavy heels when walking and thought it was worth noting to interested buyers Maybe able to get four w some reworking, but would be tight. Mit freundlichen Grüßen und freudiger Erwartung auf den Frühling 2019,Sebastian
