The Nuforce BE Sport3 bluetooth earphones fit securely, have good sound quality with a strong bass, play loudly enough for workouts, have a long battery life up to 10 hours and have a cool looking design. BeSport3 provide a secure fit for a wide variety of ears and are great for running due to their compact design and huge range of included ear tip accessories: there are 2 sizes of earfins in 3 colours and 3 sizes of eartips in 2 colours, as well as new Spinfit eartips for max noise isolation.
These are the latest 2018 version.
10 hour battery life is excellent given the small size and there is no heavy lump on the cable. There is AAC and apt-x built in, for better sounding bluetooth connection from both Apple and android devices.
BE Sport3 are compact, they have a high resistance to water/sweat (IP55) and a nice soft zip case for all the tips.
