I had a pair of the Axil I would be cautious. The rechargeable battery in mine stopped charging just over a year from buying them. The company essentially told me tough luck. They would do nothing.
I have now had a pair of Caldwell and they have been amazing. I use them all the time, shooting, working out, workign in yard, they sync to my phone great and have amazing quality for hearing your surroundings while they are in. I would recommend them over Axil. The more marketing a company has the more suspicious of the quality of product i am. Mainly due to it normally being true they have to market to sell.
