“The more experienced listeners are, the less bass-heavy they want the sound”: JBL is changing the way its flagship headphones sound, and I've heard the difference — here’s how I rate it

JBL Tour One M3 in hand.

When the JBL Tour One M3 released last year, we rated them as generally strong, albeit flawed flagship headphones. While we appreciated their solid ANC and handy Smart Tx transmitter, their audio output left us feeling conflicted. See, their soundstaging and dynamism impressed, although we felt that bass could be a tad overstated, and the highs could do with some refining.

But it seems that JBL has listened to critics and users alike, and in turn, has launched a major update to its flagship cans, including a reimagined sound curve.
