Really Cool Product Steven Davi [ 1/27/2007 ]

Was looking for a earbuds to use with my mp3 player. Have tried sennheiser,sony,skullcandy, by far these are the nicest sounding "open ear" buds i have tried. Love the open air base system that really works. I got lucky finding you in my local FRY's. Headphones are not merchandised with the other earbuds but by the mp3 players. Love the price and the sound is really smooth. Oh yeah the metal is really cooooooooooool!

High Tech Quality Michael A [ 10/18/2009 ]

The MK-510's are the ultra tech ear buds on the planet. The sound is ultra clear and crisp. High tech quality control should produce the best for the price. The MK-510's deliver! It's possible to spend $100's more and not get any better. Also, the price/quality ratio makes possible buying extra pairs for home, office, travel, and spares. I got five (5) pairs to cover all my bases/needs. The small size and durable metal form factors allow me to carry at least one pair for any occasion. Friends always ask me for product recommendations. I recommend the MK-510's. Plus, they are my choice for gifts, too. The only extra feature to add for these ear buds would be Neodymium for extra sensitivity to enhance power output and efficiency.
