The Plattan Plus On-Ear Stereo Headphones (Red) from Urbanears are designed to provide high-quality audio and a comfortable fit that integrate perfectly into a mobile lifestyle. The headphones feature 40mm handmade driver units to deliver clear, natural audio with a wide frequency response. An integrated mic and control button allow you to easily make phone calls and control music playback on compatible smart phones such as the iPhone and phones from Nokia, Blackberry and HTC. The headphones also carry an official "Made for iPhone" certification from Apple. For long-lasting comfort, the headphones have an adjustable headband that fits virtually any head size. Thick on-ear cushions provide a soft fit that will keep you listening for hours. The cushions and closed-back earcup design also help to block out ambient noise so you can focus on your music. The headphones also feature a folding design for convenient portability. The right earcup has a unique "Zound Plug" that is actually an extra headphone jack. This allows a friend to plug their headphones into yours so you can listen to the same tunes together. The left earcup has a single-sided fabric-covered cable that provides durability and resistance to tangles. The standard 3.5mm plug provides compatibility with a wide variety of MP3 players, CD players and more.
