What reviewers say

Both praise endurance and app customisation but find bass limits detail and calls suffer distortion or noise. Tom's Guide praises cancellation strongly; Les Numériques finds it useful but weaker against voices than premium rivals. Both find the fit comfortable, with Les Numériques noting firmer cushions and pressure on larger heads.
