I returned this and ordered a more expensive but better solution. I would not buy unless you like useless E-Waste then by all means be my guest. When you switch them on you hear "hello". At first glance the quality was exactly what I expected from Skechers. I Purchased these recently. everyone else is falling for the charm of premium materials but thats where it ends the drivers are weak, the sound is dull. Not snug. If you try to remove it, it stretches. Next I added the Leg assembly to the seat by loosely attaching all 8 bolts and then stood the whole thing upright on a hard, flat floor before tightening everything. Connecting to my iPhone 11 was pretty quick and easy didnt have issue for both ear buds to sync.
