Returned this hiking boot. Great accessory for drivers, very pleased with the headset. I bought these for a trip to coastal Maine and lighter hikes in Acadia National Park. I will be buying them again in the future. This does not work at all for me; I have to factory reset the headphones each time I want to pair to a different device (Ive tried to connect to a phone, tablet, and computer; I can only connect to one at a time)- Uncomfortable to wear around the neckI cannot yet confidently comment on:- Long term durability (so far so good)- Comfort (right now, MW60 feel less comfortable, but MW60 are fresh while MH40 have been worn-in for a year)- Bluetooth vs wired sound quality comparison (they sound the same I do a lot of acoustic and vocals. Su diseño y tamaño Works great with the road bike but not as great fit for mountain bike They do run a little big but still probably wouldn’t recommend sizing down. When Im not talking, they can hear the wind coming through.
