| Bottom line | Since they won't fit everyone equally well, the Polk UltraFit 3000 headphones will seem great to some users and not so great to others. | Since they won't fit everyone equally well, the Polk UltraFit 3000 headphones will seem great to some users and not so great to others. | The Klipsch Image S4i II in-ear headphones add a new, more durable tangle-resistant flat cord while retaining the S4 model's very respectable sound quality and superior comfort. | While we've heard earphones that sound better for the money, Bose has improved its in-ear headphones so they fit--and sound better--than its previous in-ear model. |
