Kilpsch has released two hot new headphone models, the S2 and S4. The oval-shaped ear tips have a moving coil design with coil dampening, and the S4 rocks a “hot rod” dual magnet motor and comes bundled with a crush-resistant aluminum case and a cleaning tool. S2 owners only get a basic cloth case with the earbuds. The S4 is expected to be released in April for $79 with the S2 following in July for $49. What are your favorite earbuds? Would you consider picking these up? [via Engadget]
