Beyerdynamic MMX 300 vs Dyson Zone

Short answer: the Beyerdynamic MMX 300. Both are rated 4.4/5 for sound quality (#9 and #11 of 134 over-ear headphones), and the Beyerdynamic MMX 300 costs $325 against $349.99 for the Dyson Zone, so with nothing between them on sound quality, price settles it.

The case for the Beyerdynamic MMX 300: It scores 91 on the Harman model, with bass from 60 to 200 Hz and the whole midrange within about half a dB of target. The tradeoff: The top end is uneven, with a 4.3 dB dip near 9.5 kHz followed by a 6.1 dB peak near 11.9 kHz and air above 10 kHz about 5.3 dB hot.

What the Dyson Zone does well: A preference score of 90 and a smooth 1.49 dB deviation put the tuning close to the Harman target, with sub-bass about 2 dB above target for extra rumble on kick drums and bass lines. The catch: A 3.3 dB dip near 3.4 kHz and a 2.1 dB shortfall across the presence region pull some bite and clarity out of vocals and guitars.

Buy the Beyerdynamic MMX 300. Both are rated the same for sound quality, and it costs $24.99 less than the Dyson Zone.

The Two Headphones In Full

Beyerdynamic MMX 300: $325.00 Amazon eBay

Pros: It scores 91 on the Harman model, with bass from 60 to 200 Hz and the whole midrange within about half a dB of target. A built-in microphone and closed back make it practical for calls, gaming and noisy rooms, and 32 ohms with 96 dB SPL sensitivity runs from a phone or laptop. Its tuning is slightly warm.

Cons: The top end is uneven, with a 4.3 dB dip near 9.5 kHz followed by a 6.1 dB peak near 11.9 kHz and air above 10 kHz about 5.3 dB hot. That can make cymbals and strings sound sharp or glassy. Sub-bass is about 3.2 dB under target, so the deepest bass notes lack some rumble.

Dyson Zone: $349.99 Amazon eBay

Pros: A preference score of 90 and a smooth 1.49 dB deviation put the tuning close to the Harman target, with sub-bass about 2 dB above target for extra rumble on kick drums and bass lines. It is a closed, wireless design with active noise cancelling, Bluetooth 5.0, a built-in microphone and a claimed 50 hours of battery, and it also works wired. Its rating matches the Austrian Audio Hi-X60 and Sennheiser HD 600.

Cons: A 3.3 dB dip near 3.4 kHz and a 2.1 dB shortfall across the presence region pull some bite and clarity out of vocals and guitars. The treble is lifted by about 2 to 3.5 dB above 6 kHz, with a peak near 7.8 dB at 11.2 kHz that can make cymbals and sibilance sound sharp. The warm lean may feel slightly full for listeners who prefer a strictly neutral sound.
