Sennheiser HD1 overview

  • 1Description

The HD1 Free In-Ear Bluetooth Headphones from Sennheiser are designed for a mobile lifestyle, with Bluetooth 4.2 and Qualcomm aptX for hi-fi sound. They can be used with smartphones to take and make phone calls or control music with up to 2 devices at once, and also support 3-way calling.

Featuring a neckband wearing style, the headphone's ear pieces are magnetic so you can join them together and wear them comfortably around your neck when they are not in use. You can also carry them in the included leather carry case.

The HD1 Free headphones have a frequency response of 15 Hz to 22 kHz and feature custom machined, stainless steel in-ear sound tunnels. The lithium-ion battery provides about six hours of listening time, and an included USB cable lets you recharge the headphones. Also included is four sets of eartips in four different sizes (XS, S, M, L), ensuring a snug and secure fit.

A Combination of Sound and Style
From the machined stainless steel in-ear sound tunnels to the leather carrying case, the Sennheiser HD1 Free are designed for an enhanced listening experience.
Smooth Passage for Natural Sound
The HD1 Free features custom machined stainless steel in-ear sound tunnels that channel the sound from its dynamic speaker system into the ear. The result combines a powerful bass response, detailed vocal projection, and a wide soundstage.
Wide Bluetooth Codec Support
The HD1 Free uses Bluetooth 4.2, with support for AAC and Qualcomm aptX codecs. Together, they ensure clear wireless transmission with true hi-fi sound from your supported devices. aptX Low Latency lets you enjoy your videos more, by keeping audio in sync with video.
Communication is All Around Your Neck
Communicate seamlessly with your mobile device with the three-button remote and in-line microphone between the earpieces. You can make phone calls and control music on the go with ease. You can connect with up to two devices at once, and 3-way calling support is also provided. Voice prompts notify you about the pairing or battery status.
Listen Longer
The HD1 Free is offered with eartips in four different sizes. They provide a snug and secure fit and block ambient noise. Furthermore, the battery lasts for six hours of listening and can be charged via the supplied USB cable.
Street-Smart Stylish
The magnetic ear pieces allow you to join left and right together to wear them comfortably around your neck when that are not in use. You can also carry them in the included leather case.
