The completely redesigned beyerdynamic T70 headphone uses transducers to achieve values of over one Tesla (a unit of measurement for magnetic flux density). That provides the listener with almost double as much volume as traditional headphones. The increased efficiency also leaves the T70 with greater power reserves for dynamic, undistorted sound & nearly lossless conversion of electric signals into sound waves. The extremely lightweight 250 Ohm voice coil provides transparency & perfect impulse fidelity. The elegant look of the T70 compliments the technical achievements, with even the smallest of details selected by h&. This model reaffirms beyerdynamic&0s commitment to world-class " Made in Germany" quality.
