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.

FEATURES SIDE BY SIDE8 topics

Yes and No describe the listed feature. Missing evidence stays unverified.

SELECTED TOPIC

Impedance

Nominal electrical load, not sound quality or loudness. Output capability and headphone sensitivity matter together; impedance alone cannot decide whether an amplifier is needed.

Beyerdynamic T5 (3rd generation)32 Ω

Manufacturer specification · beyerdynamic says the Tesla transducers of the 3rd-generation T1/T5 were optimised to 32 ohms for stationary amplifiers and mobile players alike.

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.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

Beyerdynamic T5 (3rd generation)

What it brings

beyerdynamic recommends the closed-back T5 for noisier environments, saying ambient noise is reduced and sound does not leak out; the open T1 is its alternative for quiet rooms.
Manufacturer source Manufacturer source
At 32 ohms with a rated 100 dB SPL at 1 mW, beyerdynamic says it can be connected easily to mobile devices as well as stationary amplifiers.
Manufacturer source Manufacturer source
The double-sided cable detaches, balanced XLR and 2.5 mm cables are offered as accessories, and a hardcase is included.
Manufacturer source Manufacturer source

What to check

Beyerdynamic attributes noise reduction to the closed-back construction but publishes no attenuation figure.
Manufacturer source Manufacturer source
The supplied cable is 1.4 m; the 3 m cable is a separate accessory. It weighs 360 g without the cable and is listed without a remote.
Manufacturer source Manufacturer source

Beyerdynamic MMX 300 PRO

What it brings

The analogue connection with a supplied combination-jack adapter lets the same headset plug into a PC's separate audio jacks or the combination jack of a console, tablet or phone.
Manufacturer source Manufacturer source
The boom microphone is a cardioid condenser with a published 20–20,000 Hz range and sensitivity, so its pickup can be checked against other headsets' specifications.
Manufacturer source

What to check

Ambient noise attenuation is rated at 18 dBA. The supplied audio cable uses separate 3.5 mm headphone and microphone plugs, plus a combination-jack adapter.
Manufacturer source Manufacturer source
Official sources disagree on the inline remote: the spec sheet mentions a cable with an integrated remote control, while the product page lists the headset as without remote.
