What reviewers said
AKG K240 MKII
The Austrian K240 MKII is a semi-open, wired over-ear headphone built for studio monitoring, using 30 mm XXL Varimotion drivers to deliver a broad dynamic range and precise sound. It includes a self-fitting headband, swappable ear cushions, and two cable options (straight and coiled) for flexible use. With a 55-ohm impedance and 91 dB sensitivity, it's suited for professional setups but not for noise isolation or portable use.
- Pro:Accurate and wide-ranging sound for studio work
- Pro:Comfortable self-adjusting headband
- Pro:Replaceable earpads extend lifespan
- Con:No noise cancellation, so background noise leaks in
- Con:Requires a decent amp due to low sensitivity
- Con:Not foldable, making travel less convenient

With handy features like multipoint pairing, touch controls, and a quick charge function, they remain a versatile choice for daily use and travel.
- Pro:Excellent adaptive noise cancellation
- Pro:Detailed, accurate audio with LDAC support
- Pro:Comfortable and lightweight for long sessions
- Con:No dedicated aptX codec support
- Con:Touch controls can be finicky for some users
- Con:Plastic build feels less premium than price suggests
