Some of the team tried out the Bio-Ears for swimming and sleep, it was a thumbs up.
Throughout my 20's i have been prone to ear infections, I have tried many products over the years and was thrilled to be asked to try Bio-Ears. I am in the water a lot, so I started wearing these when I swim. Problem solved - they are easy to use/re-use, and very effective at keeping water out, I would recommend.
Bio-Ears I tried out on a recent night out to a big party. I went to sleep while my friends partied on, the bio-ears were very effective. They really did keep the noise out, much better than the foam ones. If you mold them in your ear they work well. Not expensive.
