With the JVC HANC80 noise-canceling headphone, now you can choose the most effective noise cancel mode for the circumstances. HANC80 offers both "wide" and "low" noise cancellation modes. The "wide" mode targets a wider frequency range than the "low" mode, and cancels the type of noise typically found in a commercial jet cabin. The "low" mode cancels a slightly narrower and lower frequency range, one associated with the noise generated by trains and buses. The HANC80 deliver up to 75% noise reduction, and also comes with fully padded closed earpieces which help to block ambient noise, and the padded soft touch headband ensure that they'll remain comfortable throughout a long listening. It also offers a flat foldable style so that they're easy to carry or pack, and comes with a carrying pouch and a dual-plug adapter.
