Beyerdynamic T-1 Tesla Headphones

beyerdynamic T1   (First Generation)

Tesla Hi-Fi circumaural headphones, semi-open

Precision and passion:  No Hi-Fi headphones embody these principles
like the T1 from beyerdynamic.   The new Tesla drivers provide high-efficiency
with extraordinarily precise and detailed sound.

Hand-crafted in Germany,
the T1 offers superior build quality with necessary comfort for long listening
sessions.

Features:

- Semi-open, circumaural
design.

- Perfect transient and
phase fidelity (600 ohm voice coil).

- Metal storage case
included.  

Tesla Technology: 

Completely re-engineered transducers (drivers) based on a
neodymium ring magnet with optimized magnetic field characteristics.

This combination creates a magnetic field inside the transducer
which is far stronger (> 1,2 Tesla - measuring unit for magnetic flux
density - with current headphones the strength of the magnetic field is <
0,65 Tesla) than in standard headphones.

Because of this increased magnetic field, the voice coil is more
compact but still provides a very high degree of efficiency.

The membrane, consisting of a 3 layer "compound foil",
delivers an extremely precise frequency response and guarantees, in
collaboration with the strong magnet, a transparent and distortion free sound.

Frequency Response:  5 ~
50,000 Hz.

Impedance:  Rated
600 Ω.

Sensitivity:  

102 dB SPL at 500 Hz at 1 mW, which
is 6 dB more than the DT880's 96 dB rating.

1 mW is 775 mV at 600 Ω, thus 1V is
1.67 mW or +2.2 dBm into 600 Ω, so 1V gives 104.2 dB SPL.

T. H. D.:  Less
than 0.05% at 1 mW at 500 Hz (102 dB SPL).

Power Handling and MOL:

300 mW, which gives 126 dB SPL at
500 Hz.

300 mW is 24.8 dBm or 13.4 volts at
600 Ω.

Case:  Free aluminum case included. 

Also, this headphone can be fitted with new connectors for use with headphone amps that have symmetrical (balanced) drive outputs.  Just replace the 1/4" phone plug with a 4-pin XLR or a pair of 3-pin XLR (L&R).  This headphone running balanced on a Bryston BHA-1 headphone amp is fantastic!!  Headphones have never sounded better!!!

This headphone has seen very little use and is in perfect condition.

Note: additional shipping costs may apply to HI & AK.
