While best known as the leading retailer of instruments, GuitarCenter is also a great place to look for headphones and objective technical information on dozens of models. The product selection is excellent, but it is geared more for the recording professional, musician, or individual looking for studio headphones. They do stock some excellent portable headphones for iPod-users, including the Ultrasone iCans. All of the key brands including AKG, Audio-Technica, Bose, Sennheiser, Sony, Technics, Ultrasone, and Stanton are represented. The site itself is very well organized. You should not have to click more than three times to find any headphone product. Another key to the success of the site is that it is backed up with very strong customer service. The people who work here take it very seriously; they are passionate about music and instruments. They have a lot of experience with these products. Their shipping is also very good and everything arrives well packed. If you are looking for a discount on a pair of studio headphones, you will most likely find one here. Almost everything is on sale, or discounted, and in stock. A first-rate operation that should be a destination if you are looking for products that are for professionals.
