Audio-Technica ATH-M60x vs Sennheiser HD 620S

Short answer: the Audio-Technica ATH-M60x. Both are rated 3.7/5 for sound quality (#102 and #112 of 216 over-ear headphones), and the Audio-Technica ATH-M60x costs $239 against $259.19 for the Sennheiser HD 620S, and with sound quality even, the cheaper one is the better buy.

What the Audio-Technica ATH-M60x does well: Bass from 60 to 200 Hz and the upper mids sit within about 0.3 dB of the Harman target, so the core of the sound is well balanced. Watch for: Treble is rolled off, about 2.7 dB under target from 6 to 10 kHz and 3 dB under above that, with a deep 10.9 dB dip near 10.6 kHz that dulls cymbal shimmer and air.

What the Sennheiser HD 620S does well: Bass from 60 to 200 Hz is lifted about 2.6 dB while sub-bass sits within half a dB of target, giving a punchy, well extended low end. The tradeoff: At 150 ohms and 110 dB SPL/V it is more demanding than most headphones here and benefits from a headphone amp rather than a phone.

Buy the Audio-Technica ATH-M60x. Both are rated the same for sound quality, and it costs $20.19 less than the Sennheiser HD 620S.

The Two Headphones In Full

Audio-Technica ATH-M60x: $239.00 Amazon eBay

Pros: Bass from 60 to 200 Hz and the upper mids sit within about 0.3 dB of the Harman target, so the core of the sound is well balanced. At 38 ohms, 102 dB/mW and 220 g it is easy to drive from a phone and light to wear. The closed back keeps outside noise down for monitoring and commuting.

Cons: Treble is rolled off, about 2.7 dB under target from 6 to 10 kHz and 3 dB under above that, with a deep 10.9 dB dip near 10.6 kHz that dulls cymbal shimmer and air. Sub-bass is about 3.8 dB light and the low mids about 2.3 dB light, which thins the lowest notes and vocal warmth. The Audio-Technica ATH-M50x holds a higher rating for far less money.

Sennheiser HD 620S: $259.19 Amazon eBay

Pros: Bass from 60 to 200 Hz is lifted about 2.6 dB while sub-bass sits within half a dB of target, giving a punchy, well extended low end. The upper mids and presence stay close to the target, so vocals sound natural and clear. The closed back isolates well for private listening.

Cons: At 150 ohms and 110 dB SPL/V it is more demanding than most headphones here and benefits from a headphone amp rather than a phone. Treble from 6 to 10 kHz is about 2.6 dB low with a 6.9 dB dip near 9.5 kHz, which softens cymbals and sibilance. The Audio-Technica ATH-M50x holds a higher rating for a much lower price. See headphone amps and DACs with enough power to drive it.
