Are they REALLY sweatproof?

The earphones boast an angled earbud to ensure a snug fit in the ear canal when running or working out ensuring there is no risk of them falling out. They are also water resistant to IPX7 rating so there are now no excuses to exercise whatever the weather. Did I test this? Bet you bottom dollar I did, and they worked, and they worked good. I was on the treadmill for over an hour and didn't have to take the buds out once to give them the ol' wipe down.

For long runs or exercise sessions, the BLU 300 boast up to 8 hours of continuous audio playback, 250 hours of standby and can be fully charged in under 2 hrs. I wanted to put these numbers to the test, so I got them to a 100% charge and played them continuously on an old phone of mine, and it played for just over 7 hours and 40 minutes, so they are pretty close to the number.

If users wish to take an important call, skip a song or turn the volume up or down, the earphones also feature in-line controls with simple and precise tactile buttons that once you get used to where and what the buttons do, they work beautifully.


Overall, for $39.95 you really can't get much better than this in terms of a workout pair of headphones. Are these going to be your day to day headphones? No. Are these a perfect pair of headphones to keep in your gym bag or at your house when you need to do yard work or shovel snow for hours, I think so. Check them out at Brainwavz site!
