Bose Frames vs Bose Tenor Frames

The battery life, at least for now, was ok (if they aren't turned on, the battery remained at 100% for hours, it's only playtime that runs the battery down). Of course I am concerned that over time the battery life will decline, and it does not appear the battery is replaceable. Biggest concern is that it's quite easy to lose a pair of sunglasses.

Both are pretty poor on battery life playing music and seem to last about two hours. I don’t think one is significantly better or worse.

The Tempo’s sporty build is, like most exercise-focused sunglasses, designed to be lightweight, aerodynamic, and fit securely. To be clear, these aren't in-ear earphones, nor are they really headphones. Think of them instead as personal speakers that sit very close to your ear and output audio just like a small speaker would—those nearby will be able to hear it, but not as loudly as you will.

Once the light quit blinking and the Frames were charged up I installed the Bose Music app from the Google app store and went through the on screen setup instructions. There's a single button on the bottom of the right bow that is multifunctional and is used for turning on/off, pairing, answering / disconnecting calls. They connected to my S20 Ultras bluetooth without a hitch, and were ready to test out.

the plastic is light for how bulky the glasses are, and they twist and flex alarmingly. The lenses are not polarized (at this price point they should be ) and have some optical aberrations around the edges - they are basically cheap pieces of plastic and not lenses. I do not believe they have any coatings whatsoever and it looks like no effort was put into making them capable as a pair of sunglasses - the glare reflected on the inside makes them almost unusable. I've had $20 walmart fishing sunglasses outperform these

I do like the design of the sunglasses in general. I think they look a lot like the folding wayfarers that I have here from Ray-Ban, and I really like...
