Sennheiser's 500 Series of Headphones Have Pun-Tastic "Eargonomic Acoustic Refinement" Tech

Three new models have been added to Sennheiser's 500 series range of headphones, with the HD 518, 558 and 598 models using the company's Eargonomic Acoustic Refinement (E.A.R.) technology; shaped baffles which guide the soundwaves further into ears.

The three models are pretty similar, with only Hertz and visual finishes separating them. The 518 pair range from 14 to 26,000 Hertz and have anthracite ears; the 558 pair handles between 15 and 28,000 Hertz and has soft velor earpads and black finish, with the 598 pair (pictured) being the top dog with the cream and wood grain aesthetics and a frequency range of 12 to 38,500 Hertz.Sennheiser hasn't commented on the pricing nor availability of their cans.
