amazing but lost them i still have the case which i bedazeld im so sad that i lost them they where the only pair i had :(

as a music producer i never expected such a disappointment.
this has like a weird limiter that reduce the sound quality and the eq in the app just doesn't fix the error.
i understand that this are made to hear the surroundings, but this is just horrible sounding.
so, if you like music don't use this.
if you like ass sound or you want to make people suffer buy this.
i fully recommend the Life Q10 that are just amazing!

As a technician working in a loud auto shop, I bought these looking for something that kept me aware of sounds around me. At 1st I was a bit worried about the volume being an issue with them being open ear. That has proved not to be a problem. Using the volume booster in the app, these get plenty loud while still being able to be aware of surroundings. In some music with alot of bass, you do lose a little bit of sound quality as you would have with the in ear buds, but nothing that was disappointing enough not to use them. I have a pair of the Space A40's and loved those. They were my main pair up until recently getting the V20's. And I will definitely be switching between the A40's and the V20's depending on the situation.
