This process is not easy and requires rest and tact. I really needed some time and a pair of tweezers and pull the ear plugs on. These are super sensitive and can tear quickly. Then filled with the songs. Simple !! And then off to the swimming pool. Registered office: at the beginning a bit unusual, because the player sitting at attention at his temples. But after a short time this feeling disappeared. Start Player before showering and plugs also before showering in the ears: Tip. The plugs must be clean shot. The sound seems dull in the beginning, but recovered immediately. Operation is very easy for some practice. So - in water. Diving: in 1m depth the music fades. Pressure increases. But who floats already in 1m depth. Breaststroke and front crawl is fine. Keep plugs. 15 minutes and 10 minutes breaststroke crawl and with music makes the whole thing more fun. The sound is more than good. Bass and treble are well coordinated. After the test I have been annoyed that I did not order me a player. But that is probably not. Conclusion: A cheaper player who fulfills the requirements in the water and its purpose more than fulfilled. And the customer also agrees. Mir is the placement of earplugs namely a torn. Tayogo contacted and were brought to the new way.
