| Review summary | Koss hit a home run with the PortaPros. Love or hate the design, there's no denying the sound quality here: they're the ideal companion for mobile audiophiles and home theater enthusiasts. | V-Moda's Bass Freq earphones are the perfect accessory for bass-loving Creative Zen Micro owners who are on a budget. If you prefer less low end, look elsewhere. | Info unavailable | The Monster Beats by Dr. Dre Tour In-Ear Headphones offer much in the way of style and sound, but the extra-long earpieces my cause comfort and fit issues for some users. | Info unavailable |
