About the Sennheiser Momentum In-ear Wireless

On-trend wireless headphones with a sound pedigree

Our customers have loved Sennheiser headphones for years, and neckband-style Bluetooth earbuds are currently a top trend. Sennheiser's Momentum In-ear Wireless (formerly known as the HD 1) combines these two popular choices into one great set of portable headphones. The sturdy neckband stabilizes the earbuds so that they feel light and secure as you move around. And music plays wirelessly from your phone.

The Sennheiser Momentum In-ear Wireless in-ear headphones feature a neckband covered with soft, comfortable leather.

On-trend wireless headphones with a sound pedigree

Our customers have loved Sennheiser headphones for years, and neckband-style Bluetooth earbuds are currently a top trend. Sennheiser's Momentum In-ear Wireless (formerly known as the HD 1) combines these two popular choices into one great set of portable headphones. The sturdy neckband stabilizes the earbuds so that they feel light and secure as you move around. And music plays wirelessly from your phone.  

Looks good on the go

Part of Sennheiser's fashion-conscious Momentum product line, these headphones feature some nice design touches. The neckband is covered with handsome, ultra-soft stitched leather. It's subtle and elegant-looking, balanced against the flashier, mirrored-chrome earpieces.   

Stay in control

The design isn't just about good looks — there's some neat functionality, too. If you get a phone call, the neckband will actually vibrate to alert you. You can answer it through the headphones' built-in mic. There are controls for music and phone calls right on the neckband, so you should rarely have to fish your phone out of your bag or pocket. 

Energetic sound, rich in detail

Since these are Sennheiser headphones, you know sound quality was a top priority, too. Powerful dynamic drivers dish out lively sound that's nicely balanced. Each earbud features an acoustic "tunnel" made of stainless steel that carries the sound from the driver directly into your ear canal.

Comfortable ear tips that stay in place

Soft, flexible ear tips are included. You can choose from four different sizes, so you should be able to find the right fit. They help keep the headphones securely in place while keeping external sound out.

Features

Overview: The Sennheiser Momentum M2 IEBT in-ear wireless headphones are lightweight and comfortable, and have a soft leather neckband. The ear buds are the same as the Momentum passive in-ear headphones with their durable metal construction. The custom-machined stainless steel acoustic pipe gives you high-performance audio reproduction with rich, detailed sound. The Momentum M2 IEBT in-ear wireless headphones feature Bluetooth with NFC one-touch pairing, and come with a USB charging cable, and a semi-hard zippered storage case.

Design: The Momentum in-ear wireless headphones are equipped with high-performance dynamic drivers, housed in an ergonomic ear bud that is angled at 15°. The neckband is made of luxurious, ultra-soft sheepskin nappa leather, and comfortably rests at the base of your neck. The ear buds are attached to the neckband by 9" wires.

Bluetooth 4.1: With Bluetooth 4.1, the Momentum M2 IEBT in-ear wireless headphones give you freedom from cables. They are compatible with Qualcomm apt-X and AAC codec support for high-fidelity sound. Supported profiles include A2DP, AVRCP, HSP, and HFP. NFC One-touch pairing lets you immediately connect to your compatible Android devices. You can even pair up to two devices at once. When you don't want to go wireless, you can connect the M2 IEBT in-ear wireless to your computer via USB and listen to your music while the battery charges. (On-board controls do not function when the headphones are plugged in via USB.)

Ear Sleeves: The Momentum in-ear wireless headphones come with four sizes of silicone ear sleeves (XS, S, M, L) to assure you'll find the perfect fit.

Remote/Microphone: The Momentum in-ear wireless headphones has on-board controls and a microphone on the neckband. The 3-button remote lets you control volume, music playback (play, pause, play next song, play previous song), and phone functions (accept call, end call, reject call, voice control). The built-in omni-directional microphone lets you carry on your phone conversations with clarity. The headphones provide voice notification of the pairing status and low-battery warnings. The neckband also offers vibration alerts for incoming calls.

Battery: The headphones are equipped with a built-in Lithium-Polymer battery (170mAh) to give you a full 10 hours of playback from a 1.5 hour charge. The battery charges via the supplied Micro USB cable.

Customer Q&A

3 questions already asked

Q
Have RS 195 Headphones, which my wife loves. Do you have wireless earbuds that will receive the IR signal? Have a Sony HS-ST7 soundbar. Should the earbuds pair with that on Bluetooth?
[ david  May 08, 2020 ]
1 answer
A
We have some extra headsets that would work with that RS-195 transmitter but they are all over-ear. That Sony soundbar can receive Bluetooth, but not transmit Bluetooth. Sennheiser does make a similar product with an in-ear headphones - the RS5000 https://www.crutchfield.com/I-rET1c290/p_143RS5000/Sennheiser-RS-5000.html
