Time for an upgrade from my last New Bee, Bluetooth Ear Piece.The build quality seems good for the price. They feel like a more expensive product.The sound quality is very good for a wireless earphones at this price.I've had them for a week now, used them every day and haven't had any dropouts the connection is rock solid. Connects to both my phones.For me the fit is great, designed perfectly right, sitting around my ears, I have used these for running a couple of times now and didn't have to adjust them or push them back in at all! They are very light and don't feel like a weight in your ear. The profile is much better for wind noise than the bose soundsport and Power Beats Wireless.I haven't used them for more than a couple of hours without putting them back in the case so I can't comment on battery life, I haven't had to charge the case since I got them, if they are as good as the old New Bee Bluetooth, I don't think I need to charge it from a hold days use or more.Bluetooth earphone can also be used on both ears which is great!Call quality is on a par with considerably more expensive pairs of bluetooth headphones which also have. You can tell someone is talking on headphones/hands free but its not off putting. Highly recommended.
