I must point out that while these are NOT noise canceling headphones, the acoustic isolation of the cups, make the earphones more like earmuffs

The cord is tangle free and the isolation is perfect I can’t really hear the noise outside, so I can really focus on the music

Sony indicates that bass boost is accomplished using “an acoustically tight seal for superior sound isolation, deep bass sound and tight base response

n’t get me wrong...
