Sony uses 13.5 mm driver units in these headphones. While lightweight and small enough to fit inside the ear, they also deliver a good bass sound and wide frequency range (down to 18 Hz.) Neodymium magnets give the headphones maximum energy at a minimal size and weight. Sony's Acoustic Twin Turbo Circuitry will deliver powerful bass sound for high efficiency, giving you consistently good sound in an extremely lightweight pair of headphones. The open-air design allows for ambient noise to enter the ear, a safe feature for exercisers as you will hear car horns, passing bikers and dog barks. The cord is one meter long (3.3 feet) and the nickel-plated mini-plug offers crisp sound delivery. If you are looking for a quality-sounding, lightweight and stable pair of headphones, with the added ease of an in-line volume control, then these MDR-W24V headphones should fit the bill.

Rating : - Great workout headphones
I have been using these for a few months now after searching for a good set of non ear bud headphones for working out and running. Its been annoying to me to have my ear buds fall out while exercising and having to crank the sound up as they dont fit snuggly enough to get full range. These although cheap are high quality earphones for the price that stay in my ears. Its only been a couple months so time will tell but for now, I have stocked up b/c good headphones that are cheap and wont fall our are so hard to find.
