A:AnswerI am a safety professional in the oil and gas industry so naturally the first thing I did was check on the ANZI Z-87 compatibility for this product. A safety guy will always check on the frame of any wrap around glasses as this is typically where the Z-87 stamp is located. The Bose frame does NOT have this stamp. A friend of mine checked in to getting a Z-87 rated lens for this frame (Through Walmart I believe) and he informed me that this IS an option. Since the Bose frames DO NOT have the Z-87 stamp on the frame you would want to make sure that you kept the paperwork from Walmart indicating that the lens are Z-87. (Which is an impact rating) so that you could provide this to your safety professional if requested. Hope this helps.
A:AnswerHi Antonio,
Tempo has larger speakers to accommodate wind while running or riding a bike. This allows for a larger battery increasing the hours of use.
Hope this helps
Thanks
A:AnswerI wear them while I ride my Harley and I can hear the music but not well enough for my liking. My Harley is quite loud, wind isn't what keeps me from hearing. There is a 14-day no-questions-asked return policy, buy them and go for a ride. If they don't work for you take them back..
A:AnswerThe best reason for getting these was for my son to bring his music with him while he fished. You can change the lenses to clear and wear them inside. I cannot hear them when they are on next to me at a reasonable volume. And lastly, when lots of people have issues with their ears and need to keep them clear its nice to have this alternative. I hope this helps.
A:AnswerI took mine to my optometrist and they sent them off and had my progressive bifocal lenses made and installed, it was cheaper than going through Bose
