Finally, I wanted to try the Speedo first, since the number of positive and negative comments kept the roughly balanced. So I thought to myself: "Come on, try it by yourself time out (and if it's no good, you can exchange him again to stop)."
When the unit arrived, I naturally wanted to first try out the earplugs and was very skeptical whether this can really be waterproof even in the dry. Also, I'm not a fan of temples and somehow attaching was quite Friemelei ..
This morning at the pool, I then took the test and I have to say that the device has the first 1-2 Railways works surprisingly well, but then the plug has solved something and there was water in his ear, so I have nothing more or could hear only very weak.
Did it then adjusted again and again tried, but that was me then pretty quickly on my nerves. I think for Brustschwimmer the device is really great, but for people who do not fit only crawl so right. At least the _Stöpsel_ suck not really - the player itself is super. Good to use, load quickly, firmly to the swimming goggles - no problem.
Will the unit to return today and try the Sony NWZW273 tomorrow. I'm curious times, whether the better stops (in the promotional video, the thing seems to be working really wonderful) ...
