Sennheiser's NoiseGard™ technology uses tiny microphones and advanced circuitry to cancel out extraneous noise as you move.
It'll help you focus on the enjoyable, well-balanced sound signature, which has a slight nod toward the low frequencies for some extra punch.

Overview: The Sennheiser HD 1 Wireless headphones have a closed circumaural (over-the-ear) design with Bluetooth technology and NoiseGard Hybrid active noise cancellation. The headphones come with a straight connecting cable for those times when you can't go wireless, a USB charging cable for the internal battery, a soft cloth drawstring pouch, and a semi-hard clamshell case for storage.
Bluetooth: The HD 1 Wireless headphones have Bluetooth version 4.0 + EDR which pairs to your phone or audio device in seconds. You can make and receive phone calls and stream audio wirelessly in a range of up to 33', depending upon environmental conditions. Bluetooth 4.0 is compatible with devices having Bluetooth versions 1.1 through 4.0. The headphones have the following profiles: Headset Profile (HSP 1.2), Hands-Free (HFP 1.6), Audio/Video Remote Control Profile (AVRCP 1.5), Advanced Audio Distribution Profile (A2DP 1.3), and Device ID Profile (DIP 1.3).
aptX: With aptX audio coding, the HD 1 Wireless headphones deliver clean, crisp audio in full stereo. If your Bluetooth audio source supports aptX, the headphones will automatically stream music wirelessly in aptX high-quality mode. If the device is not equipped with aptX, the music will be streamed in the standard quality mode.
Near-Field Communications (NFC): If you are using the headphones with a device that supports NFC, you can wirelessly connect the device by touching, or placing it within close proximity of, the "N" logo on the front of the left earcup.
NoiseGard: The HD 1 Wireless headphones feature the NoiseGard hybrid Active Noise Cancellation. NoiseGard is a combination of two noise-cancellation systems with a total of 4 microphones. The two microphones on the outside work as a Feed-Forward system that reduces high-frequency noise, while the two on the inside of the earcups act as a Feed-Back system to reduce low-frequency noise. Together, the two microphone systems reduce ambient noise by up to 25dB over a broad frequency spectrum. The NoiseGard hybrid Active Noise Cancellation system only works when the headphones are powered on. Even with the power off, the closed, around-the-ear design shuts out much of the external noise.
Rechargeable Battery: The HD 1 Wireless headphones are powered by an internal, 3.7VDC 600mAh Lithium-Polymer rechargeable battery. The battery charges in about 3 hours via USB power (using the supplied Micro USB cable) from a laptop, an AC-powered USB charging port, or a mobile 12-volt USB charging port. While charging, you can continue listening to music or making calls from your smartphone via a Bluetooth connection. A fully-charged battery provides approximately 22 hours, using both Bluetooth and Active Noise Cancellation. You can keep track of the remaining battery life through the multi-color LED and voice prompts.
VoiceMax: The headphones utilize VoiceMax technology with two built-in microphones for voice communications. With two microphones, speech quality is enhanced, and external noise is removed. VoiceMax allows you to conduct clear phone conversations, as well as voice control functions with your smartphone, without the need of an external microphone.
Phone/Music Controls: You can control your streaming audio and phone calls using the 3-way multi-function button on the bottom of the right earcup. The button uses the same protocol as most other headphone remote controls with a pattern of button presses, however some smartphones may not support all functions. Phone controls allow you to accept, end, and reject calls, and redial. If you receive a call during another active call, you can choose to accept the new call by ending the active call or placing it on hold and toggling between the two calls. Music controls include play/pause a song, play the next or previous song, and rewind or fast-forward a song. Phone and music controls are only available if the headphones and smartphone are connected via Bluetooth.
Audio Cable: If you can't listen to the headphones wirelessly, you can still enjoy your music through a wired connection. An attachable 58" straight audio cable is provided with a right-angled 3.5mm mini-plug. In Active Mode, you can still take advantage of NoiseGard hybrid Active Noise Cancellation when using the headphones with the audio cable, however, the phone and music control functions will be disabled. In Passive Mode, Active Noise Cancellation is turned off. An Airline audio adapter is included so you can plug into in-flight entertainment on most domestic and international airliners. Phone and music controls are not available when the audio cable is plugged in.
Design and Materials: The HD 1 Wireless headphones are equipped with lightweight brushed stainless steel sliders, a luxurious, real leather headband, and redesigned ear cushions with memory foam. The headphones fold into a compact package that you can place in the silky drawstring pouch or the semi-hard clamshell case with a zippered closure.
