Sleek Audio on Monday launched its wooden SA1 in-ear headphones which can be tuned and worn either as wired headphones or wirelessly. The SA1 set has 6mm drivers housed in a Siam rosewood body. Thanks to Sleek's optional Kleer wireless system, the wires can be detached and users can listen to music wirelessly. Frayed, pinched or otherwise damaged wires can be replaced anytime.
