Plus the base has been improved, which is great as when training I always listen to Spotify Run N Base 170-175 BPM and the Aeros make the play list sound great.

Some people report a feeling of sound pressure when the noise cancellation is working, but its an illusion and the reason it happens is because the lower frequencies are stopped from reaching the ears, but the higher ones do (Noise cancelling only stops the lower frequencies). Iphone product Red body was in good condition. It does include the lock so thats a plus you will not have to go buy a hitch receiver lock. There are a lot to choose from but there are still more they could add.
