However, if you have a disability we are here to help you. Please call our disability services phone line at 1-800-123-4567 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

Digital Noise Canceling for less distractions Digital Noise Canceling reduces a variety of ambient noise when listening to music. A microphone built in to the headphones works with the digital noise canceling engine to cut out unwanted sound. The headphones select the optimal mode (airplane, train, or office) based on an intelligent analysis of the environment. Activate or deactivate noise canceling using the on/off switch.

Neodymium dynamic drivers deliver precise sound Lightweight 1.57 in neodymium dynamic driver units enable the headphones to deliver a punchy, rhythmic response to even the most demanding track. Combined with a highly sensitive diaphragm, you'll be able to turn the headphones up louder and still enjoy clear, precise audio across the spectrum.

Tight bass with Beat Response Control Beat Response Control technology delivers tight, deep bass response, making it perfect for low-end focused music styles. An air vent maximizes airflow within the low frequency range, optimizing the efficiency of the diaphragm to enable more accurate reproduction of bass rhythms.

High sensitivity for a loud, clear sound With a high sensitivity of 100 dB/mW when using the audio cable (98 dB/mW with noise canceling on), these headphones are highly efficient in converting electricity into acoustic signals. This means you hear a louder sound across the entire audio spectrum (compared to less sensitive headphones) when listening to music through the same source and at the same volume level.

Take calls hands-free with built-in mic Whether you're chilling in the living room or lounging in the garden, when a call comes in, you won't need to touch your phone. Simply pair your phone with the headphones via Bluetooth, and use the built-in microphone to chat away.

Support for popular AAC and aptX codecs These headphones support popular, high quality codecs, including AAC for iPhone/iOS users, and aptX® for pure wireless sound that doesn't compromise on audio quality. The aptX® codec enables pure wireless audio to be sent wirelessly over Bluetooth by reducing the size of audio files.

Cushioned earpads for total comfort Listen in total comfort. These headphones have soft cushioned earcups that cover the whole ear, so you'll enjoy the long-lasting comfort you need for listening to your favorite albums back-to-back.

Stainless steel slider for comfort and durability Listen to your music in total comfort. A stainless steel slider in the headband allows you to find the perfect fit, while providing excellent durability when travelling.

Listen with the supplied audio cable Feel like listening to your music without Bluetooth" Just connect the supplied audio cable to your headphones and plug into your favorite music player for high-quality sound. The cable is 3.94 feet long and designed for durable everyday use.

Why NSI Protection Plus?

Our service plan is an economical way to extend the terms of your product's manufacturer parts & labor warranty.

Most manufacturer's limited warranties leave customers with no protection against the rising cost of repairs.

Even the best products can malfunction and the most minor repairs can cost hundreds.

About NSI Protection Plus

Administered by Warrantech and insured by AmTrust Financial, NSI Protection Plus is the largest service network in the industry with 30 years of building the network and over 22 million in paid claims.

The most comprehensive repair plans in the business!

  • Day one coverage on special features
  • Removal and reinstallation coverage
  • $25 Laundry credit (Washers and Dryers)
  • 5 year appliance contracts include 10 year major component coverage
  • $250 Food credit (per incident, eligible products)
  • The only true "No Lemon Guarantee" in the business
  • No "CAP" on repairs or replacement, unlimited repairs.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
