How to read this comparison

Manufacturer facts for the exact models shown. Not a quality rating or a test result.
“Different” means the known values differ, not that one is better.
Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

Start with your listening environment. Open and closed earcups suit different surroundings. A closed back is not the same as active noise cancellation. Check the exact cable and headphone output. We do not turn impedance, driver size or unpaired lab results into a sound-quality score.

Beyerdynamic TYGR 300 R

What it brings

At 32 ohms with a rated 96 dB SPL at 1 mW, beyerdynamic says it works on PC and on PS5 and Xbox Series X through the controller jack.
Manufacturer source Manufacturer source
Its rated headband pressure is 2.9 N, and the velour ear pads and headband pad are listed as replacement parts.
Manufacturer source

What to check

It has no microphone, so voice chat needs a separate microphone; beyerdynamic designed it for gaming in a quiet environment, and says outside noise is virtually unattenuated.
Manufacturer source Manufacturer source
The 1.6 m cable is fixed, and beyerdynamic notes that maximum volume depends on the connected platform's sound card.
Manufacturer source

Sennheiser HD 660S2

What it brings

Both a 4.4 mm balanced and a 6.35 mm unbalanced cable are included with a 3.5 mm adapter, and the velour ear pads are replaceable.
Manufacturer source Manufacturer source
A revised 300-ohm voice coil, more compliant surround and vented magnet system are designed for more sub-bass, and sensitivity is rated at 104 dB SPL at 1 V.
Manufacturer source Manufacturer source

What to check

At 300 ohms with a rated 104 dB SPL at 1 kHz / 1 V rms, check that your amplifier or audio source can drive the headphones properly.
Manufacturer source Manufacturer source
The open-back design leaks sound and lets outside noise in, and the supplied cables are 1.8 m long. An XLR-4 cable is sold separately.
