Sennheiser HD 620S vs HD 480 PRO

The Sennheiser HD 620S are closed-back over-ears from the Sennheiser Consumer Hearing division, while the Sennheiser HD 480 PRO are a product of the brand's professional division. While they're technically products from different companies, both headphones are very comfortable professional tools that can provide a good amount of passive isolation without ANC. The HD 480 PRO have a sound profile that's well-aligned with our target, while the HD 620S rolls off same bass and can't render the mid-range with as much detail. They have similar weaknesses too, as glasses and long hair tend to disrupt the seal created by both headphones, resulting in some deviations in bass delivery. Ultimately, choosing between them will come down to whether the HD 480 PRO's sound is worth the additional outlay.
