The details of the strap, heel, and embossing are very lovely. No instructions but easy enough to figure out. This product is very flimsy. Great value for the cost. The Savi 8220 offered stereo speakers on the headset as opposed to the 720 series of binaural speakers. It is easy to activate with the paddle switches, both in low, high, and strobe modes. Turns out it was a washer. The earbuds are also easy to place in the case for charging, no mixing left and right and the case recharges very quickly (fast charge less than an hour) via a USB-C connecter. Feels very high quality and good features. My nit has already been commented on.
