Had to unplug and replug like 10 times to get it working again. Have a Blaupunkt speaker on the landing connected to it Someone more limber may not have such an issue. I bought these (and a pair for my wife) specifically for mowing the lawn. I purchased the XL, which is supposed to fit sizes US11-12. My theory used to be"you get what you pay for", so I was a little hesitant. Bonne qualités I fully charged the headphones thinking maybe this would help (I agree it doesnt make much sense but wanted to try everything), but a full charge makes no difference - neither a Moto Z2 or Z4 can find this device, assuming its actually sending out a pairing signal at all. With those aside, this is without doubt an absolutely brilliant phone for the price and I highly recommend it. It?s very well made, great design and of reliable strong materials.
