Pioneer Electronics (USA) Inc. today expanded its on-ear headband headphone offerings with two new products, the flagship SE-MJ591 audiophile headphone for critical listening, and the SE-NC21M noise cancelling headphone. Each new headphone model is designed to optimize the listening experience in very different environments. "There's an emotional connection with music, and when you hear more of the details, it changes the listening experience significantly," said Chris Walker, director AV marketing and product planning for the Home Electronics Division of Pioneer Electronics (USA) Inc. "Our new SE-MJ591 and SE-NC21M provide great sound quality to both serious listeners and music lovers on the move, so what you hear is remarkably close to the original music." SE-MJ591 For over 50 years Pioneer has worked to develop headphones incorporating advanced technologies to deliver the highest level of sound quality, and the high-end SE-MJ591 reflects the company's commitment to its years of headphone research and development. The model is designed for highly accurate sound reproduction across the entire spectrum, enabled in part by newly designed 40 mm drivers and an on-ear design that naturally reduces disruptive external sounds. The SE-MJ591 features high-quality construction with metal components and ultra-soft ear pads and headband for the ultimate comfort during longer listening periods. The headphones are intended to match the sound quality of high-end audio systems, making them the ideal accessory for serious listeners looking for high-end audio performance, both at home and on-the-go. The SE-MJ591 headphones are lightweight, fold up to a compact size, and include an attractive and durable protective carrying case for convenience and transportability. The SE-MJ591 headphones will be available in April with a suggested retail price of $299.00. SE-NC21M Continuing on the success of Pioneer's noise canceling earbuds launched in 2011, the SE-NC21M offers the same benefits, but in a new on-ear version. The SE-NC21M is designed to reduce up to 90% (measured at 300 hz) of ambient noise, ideal for noisy environments such as airplanes and public places where constant background noise can interfere with music listening. The headphones feature lightweight construction for comfort during longer listening periods. Battery life is up to 120 hours of noise cancelation using a single AAA battery. The SE-NC21M will also continue to function as traditional headphones if the battery dies mid-use. The SE-NC21M headphones are lightweight, foldable and come with a carrying case for on-the-go convenience. The SE-NC21M headphones will be available in May with a suggested retail price of $119.00.
