“Handcrafted in Heilbronn” sounds like a nice starting point for a pair of headphones.
Throw in something called “Tesla Technology” and you’re describing the latest headphones from beyerdynamic, the DT 1350.
According to beyer, Tesla Technology is a reworking of the traditional neodymium magnet driver configuration by making the magnet into a ring. In beyer’s view this should improve sound and make the driver more efficient as well.
The DT 1350 is an on-ear (supraaural) design with swiveling cups (up to 90 degrees). The ear cushions are removable and the headband can be extended.
Price: $299.
