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
- Semi-open, circumaural
- Perfect transient and
phase fidelity (600 ohm voice coil).
- Metal storage case
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 ~
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
300 mW is 24.8 dBm or 13.4 volts at
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.
