This is the perfect product for a Good, Bad, Ugly review...
The Good:
Cool product, but it almost feels like a solution looking for a problem. Even so, still cool.
Product packaging was great, you feel like you are opening a premium product. Inside the box are the glasses, magnetic charger, carrying case, cleaning cloth and quick start/cheat-sheet/obligatory warranty and handy reference to give your optician for prescription lens replacement. The included lenses are straight thru and are advertised as blue light filtering. Controls are simple with on/off, volume up/down and a cool slide touch-pad controller all on right frame. Very intuitive. The fit was nice. Quite lightweight and could easily be worn comfortably all day.
PRO TIP: To preserve battery life, the Echo Frames go into "Sleep Mode" when placed upside down to preserve battery life. While a cool feature, for those of you who require wearing glasses all day, this kind of a no-starter since it's not germane to your needs, but for those who can remove the glasses for periods of time, a cool feature.
As for the Bluetooth for phone conversations, these are well above average. I tested several calls from my home office, Ford F-250, Ford Fusion Hybrid, Toyota Prius and walking around the neighborhood. Several of the conversations were 15+ minutes. I did not tell person on the other end I was using BT until the end of the conversation. In every situation, the people on the other end were honestly surprised. They said it sounded great and other than the occasional cell/BT hiccup, they were impressed. From my end, it always sounded good (albeit a little quiet {more on that later}) but overall, as good as any other BT devices for conversation as I have used. Well done.
The Bad:
The build quality is honesty probably pretty decent but the initial feel if a bit flimsy in tactile feed-back. I think this is more impression than reality, but only long-term testing will tell. I'm sure the quality is commensurate to Amazon expectations, just a note I could not avoid to share
While the BT for phone conversations was pretty good, these are pretty weak for music. To be fair, they are not designed to be musically robust, but the sound is thin. I guess they are perfectly fine for background music while in the office or walking around the lake, the music sound quality is "mmehh" at best. On the positive side, being open eared, you are certainly aware of your surrounding sounds for safety and awareness. Kind of a wash in the end.
Additionally, the music volume was (to me) disappointing. But if I am to be honest, I was a professional musician in the late 80's/mid-90's and I spent WAY TOO MANY hours in front of two Mesa Boogie 4x12 cabinets powered by a Mesa Boogie Simuclass 295 Power Amp and a Mesa Boogie Tri-Axis pre-amp. So, is the volume the fault of the Frames or more the fault of an early 20's semi-rock star who had no mortality who is now 50? Probably the latter, but important to note for my experience.
The Ugly (and not so Ugly):
Oh my, these things on my ugly mug make me look a bit goofy. The fault of the Frames? No. They look great on my gorgeous wife. They are certainly better on some than others.
End of the day as I mentioned earlier, these may be a solution looking for a problem. But they are cool and certainly useful. I think I will use them more than I originally thought. To me the high point is the BT phone audio. I have purposefully sought these out knowing I have a long call coming up and chose these over a plethora of other great Technical Insider Network BT products I could have used. But I would NOT use these for a workout or for high quality music.
I would recommend them to a friend (with caveats), but good choice for a product that serves a niche market. I am glad I have them.
Postscript notation: Apologies for last picture... My wife made me put it in review since she LOVES her 7 Christmas trees... Only 2 shown, but there are 3 on main level, 2 upstairs and 2 in basement. I think she might a Christmas problem.
