AH-C351K
The cheap earbuds that come with portable audio and media players have poor fidelity and come loose too easily, especially when running, for example. Denon's AH-C351 Advanced In-Ear Headphones are the ideal choice for today's active lifestyle, with a comfortable and secure in-ear fit that provides additional isolation from external ambient noise. Equipped with Denon's exclusive Acoustic Optimizer technology, which balances sound pressure on both sides of the driver, the AH-C351 features large 9mm driver units for an extended frequency range (20Hz to 21kHz). Its high efficiency (110 dB/mW) ensures a longer battery life for the portable player, and the headphones come with three different sizes of ear tips for a comfortable and secure fit, and the ear tips can be easily removed for cleaning. The tangle-resistant cables (20" and a 31" extension = 51" total length) feature high-purity oxygen-free copper wiring and are also designed with special-length cord sets for people on the move to minimize cable pull PZA More features
