Beautifully unconventional

Sennheiser's first-generation Momentum headphones earned rave reviews from our customers and staff for their clear, accurate sound and tasteful but original good looks. With the Momentum 2.0 Wireless, you get some nice design tweaks and the added bonus of cable-free Bluetooth technology. It's a striking mix of classic style, tried-and-true sound, and modern-day conveniences.

Built to travel, and sound good doing it

Like the original Momentums, these lightweight over-ear headphones sport a cool throwback look, but Sennheiser gave this new wireless version a collapsible folding design for easy transport and storage. Heavy-duty, rugged parts like stainless steel sliders and a leather headband make them incredibly durable. Life on the move is further improved by Sennheiser's NoiseGard™ technology, which uses tiny microphones and advanced circuitry to cancel out extraneous noise. It'll help you focus on the Momentum 2.0 Wireless' enjoyable, well-balanced sound signature, which has a slight nod toward the low frequencies for some extra punch.

Go wireless and answer calls with Bluetooth 4.0

To make listening on the go even easier, the Momentum 2.0 Wireless headphones connect to your Bluetooth-enabled smartphone or tablet. No dangling cord needed.

Buttons on the right earcup let you control music playback and volume, and also answer phone calls. The built-in VoiceMax microphone captures your voice for clear call quality. You get up to 22 hours of wireless playback with noise cancellation on a full charge. If you're in a situation where you don't need wireless, a cable is included for both passive and active listening.

Relaxed, comfortable fit

The Momentum 2.0 Wireless 'phones features oversized cushioned ear pads covered in soft, luxurious leather. Sennheiser gave them larger earcups than the original Momentums, for an easier fit over the ear — one of two key comfort upgrades. The second is a slightly larger headband, which helps these headphones rest on your head without clamping too tightly.

Product Research


Overview: The Sennheiser Momentum Wireless (M2 AEBT) 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 Momentum 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 M2 AEBT 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 Momentum 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 M2 AEBT 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 Momentum 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.

Customer Q&A

Crutchfield asked: Why did you buy this?
Good reviews plus positive experience with Sennheiser products [ PEDRO  Aug 24, 2017 ]
It was between these and the PXC 550 I loved the retro look and sound quality of these, but I really liked the 50hr battery life of the PXC 550. My roommate had a set of the 550 they were awesome, They got stolen. [ Paul  Mar 19, 2017 ]
replacing Sennheiser RS175 due to signal loss frequently. [ LORI  Feb 26, 2017 ]
great reviews! [ Jeffrey  Nov 03, 2016 ]
I wanted to give these headphones a chance however, I find the ear cups to be a bit difficult to maintain a proper seal. The noise cancelling on the Sennheiser Momentum 2.0 Over-ear Wireless is rather modest compared to the Bose QC 35. I will say that the Momentum's have great sound and punchy yet clear bass, mids, and highs. While I like the sound and the reliability of the wireless. I'm not really sold on the Active Noise Cancelling or call quality using the Momentum's. [ MUHAMMAD  Sep 09, 2016 ]
performance [ Valentin  Aug 16, 2016 ]
Great reviews [ Warren  Jul 29, 2016 ]
Quality, features, style and review comments [ A.C.  Jun 26, 2016 ]
Reviews and the quality of all of my other Sennheiser headphones/headsets. Beats is marketing BS and BOSE doesn't seem to have the quality it used to. [ David  May 23, 2016 ]
I wanted to treat myself to a great pair of BT headphones. These are highly recommended. [ Art  May 10, 2016 ]
2ND Pair, they're really excellent. [ Richard  Mar 31, 2016 ]
After extensive research on wireless headphones at this price point, these offer the best wireless sound quality in a headphone with active noise cancellation. Other features put these over the top. They will work even after the battery runs out with a wired audio connection and this offers excellent sound quality as well. Not to mention a 2 year warranty [ Adam M.  Mar 10, 2016 ]
Reviews indicate these are the best [ Benjamin  Mar 01, 2016 ]
Based on operational checks with other various headphone systems, reading numerous reviews, and adviser Kay's information, I believe I've made the correct choice. Looking forward to receiving these wireless momentum headphones! [ Carson  Jan 08, 2016 ]
Adviser recommended [ David  Dec 30, 2015 ]
Love the look (Ivory) and awesome sound. Much better than my Bose, much more transparent sound stage. [ EDWARD Y  Jul 25, 2017 ]
Excellent sound signature for our tastes with bluetooth. I have the wired version, and wanted the wireless for my partner who is not that into audio but finds herself using these often and enjoying them. Stylish, comfortable, good sound. [ Barry  Jul 12, 2017 ]
Samsung Level On Pro wireless headphones had broken during travel, 2nd pair of such to do so. Have a wired pair of the Momentum and pleased with them, need a wireless option as well. [ Victoria S.  Apr 23, 2017 ]
I think there one of the best Headphones out there (for the price) [ DETLEV  Sep 08, 2016 ]
reviews [ John  Aug 07, 2016 ]
Read good reviews. Hope they feel and sound good. I tried on a pair of Beats and Bose. Didn't care for the fit of either one. Plus the Beats seemed very cheaply constructed for the amount of money. [ Anthony  May 16, 2016 ]
Was waiting for a sale on this item. Crutchfield had best price found. [ JOHN G  Apr 30, 2016 ]
Previous satisfaction with Sennheiser. [ Richard  Mar 16, 2016 ]
noise cancelation, wireless, sound quality, build [ Robert  Feb 09, 2016 ]

Sennheiser. Wireless. Stylish. Rechargable. Also seconds as a stereo headset for my cell phone. [ Christopher  Dec 28, 2015 ]

4 questions already asked

this item says it's currently in stock ... is this from the new shipment of momentum wireless 2.0s that have the bluetooth connection problem solved? or is this existing stock from before the recall?

Bought mine on Oct 13 2015, Crutchfield shipped me the new model REV 02 dated 2015.
[ Gregory  Oct 29, 2015 ]
I don't know if these are the new revised headphones, but I ordered a pair about a week ago, but I had to return them because the box said REV 01 dated 2014.
[ DarklyX  Oct 15, 2015 ]
I forwarded your question to an Advisor and they responded with the following: Our entire stock of these Sennheiser headphones are from the newly released Sennheiser stock with all Bluetooth issues completely resolved. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.

expected on 14th august ?????? why so far away ?!?!??!

This is the date we reasonably expect to have this product in stock based on anticipated demand, communications from the manufacturer and other factors. This is a good faith estimate, not a guarantee.

Is the apt-x technology compatible with ios?
[ Drewdrew  Mar 10, 2015 ]

I posed a similar question to Sennheiser customer service and I copied the following from their response: Thank you for contacting the Sennheiser Technical Support Team. The part number #506250 is the part number for our M2 AEBT Black (MOMENTUM Wireless Black). The Apt-X codec is one element that helps provide the best possible sound quality via Bluetooth. If the Apt-X codec is not built into the device you are connecting to the headphones will still work you via Bluetooth you simply will not have the benefit of Apt-X. The Apt-X codec makes a huge difference when you are comparing lower level devices that might not have the best Bluetooth chips in them however when you are considering Apple devices these items have excellent Bluetooth chips in them so the addition of the Apt-X codec does not affect the audio quality very much. The MOMENTUM Wireless models sound excellent when connected to an Apple device via Bluetooth and I am certain that you will not be disappointed.
[ Flyer  Jan 05, 2016 ]
No, it is not compatible with Apple iOS
[ Christopher  Mar 10, 2015 ]
Can you still use the headphones thru a wired connection if the battery dies?
[ Drew  Mar 03, 2015 ]
11 answers
Yes, but you lose the noise canceling function.
[ Jerry  Mar 04, 2015 ]
Yes, and what great is that the sound quality doesn't change compare to noise canceling feature on. Bose qc 25 has really low sound quality when noise canceling feature is off.
[ Zehao  Mar 03, 2015 ]
I Don't know
[ E HARRY  Mar 03, 2015 ]
Yes you can. It includes a detachable 3.5 cable, and you can also use them wired if they are plugged in with usb
[ Joseph  Mar 03, 2015 ]
Yes, these headphones work in three different ways. The first way is as a wireless/Bluetooth active noise canceling headphone when the battery has a charge. The second way, again with the battery charged, is to use the included stereo connection wire for increased frequency response and active noise cancellation. The third way is as a passive set of headphones, the same as any high quality non-wireless headphone, without the battery charged. Each one of the three ways provides an exceptionally clear and balanced listening experience. I've had mine for about two weeks now and can say that they are the best set of headphones I've ever owned. Give them a won't be disappointed.
[ Stephen  Mar 03, 2015 ]
Yes. You can use them as traditional headphones without power.
[ Matthew  Mar 03, 2015 ]
Yes, you can use the headphones wired, with or without power.
[ David  Mar 03, 2015 ]
I honestly haven't tried that, the Battery lasts forever. But I don't think it works without battery power.
[ MICHAEL H  Mar 03, 2015 ]
Yes, you can use the M2 wired even if battery is dead. I believe you can use ANC wired as well.
[ Tim  Mar 03, 2015 ]
Yes, they still work as normal headphones without the battery. The noise cancelation will not work if the battery dies, however.
[ Collin  Mar 03, 2015 ]
I've turned off my headset and have used the wire
[ DINH  Mar 03, 2015 ]
