Key strengths
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.
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.
The double-sided cable detaches, balanced XLR and 2.5 mm cables are offered as accessories, and a hardcase is included.
Before you buy
Beyerdynamic attributes noise reduction to the closed-back construction but publishes no attenuation figure.
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.

- Active noise cancellation
- Not listed by the manufacturer
The reviewed exact sources do not explicitly establish active noise cancellation absence. Preserve separately sourced acoustic design and passive attenuation; they cannot turn omitted ANC into a false capability.
- Microphone
- Not listed by the manufacturer
The reviewed exact sources do not explicitly establish microphone absence. Omission from a package or technical inventory, a stereo audio connector, and a without-remote statement do not establish microphone=false.
