The open-air design removes undesirable resonance by allowing outside air to pass through the headphones; the result is a better sounding headphone. The open-air design is also a key factor in keeping you safe while you exercise. The headphones allow outside noises like horns, passing bikers and oncoming dogs to meet your ears, even with music playing. With sixteen millimeter drivers, although miniscule, you can expect to hear a good bass sound. Neodymium magnets, a rare feature on such economically priced headphones, provide maximum energy with minimal size. Meanwhile, the Sony Acoustic Turbo circuit is included for high efficiency; it gets high sonic output from your portable stereo, and extends bass response.

The MDR-A34L's oxygen-free copper (OFC) Y-style cord is double-sided and is 3.9 feet long, allowing for ample movement and separation from the sound source. The gold-plated, L-shaped stereo mini-plug fits mini-plug jacks, not the full-size stereo jacks. The headphones are a flat black color.
