Today, we will look at theSennheiser Momentum True Wireless 3 Bluetooth Earbuds.  This article will discuss some design features, build quality, ease of use, and some of my sound impressions.   

I have owned several true wireless earbuds over the years, one of which was the Momentum True Wireless 2, although it has been some time since I have owned them.  I generally don’t utilize in-ears, earbuds, or earphones for much of my serious music listening.  However, that all changed this year after CanJam when Wayne from TSAV sent me home with several items to review.  One of which was the Momentum True Wireless 3.  

Until then, I was using the latest generation 3 Apple AirPods as I am heavily invested in the Apple Eco System and didn’t want to spend too much on wireless earbuds.  However, in hindsight, my 3rd Generation AirPods get nearly as much consistent use as any other headphones in my collection just based on the simple fact that I work out 90-120 minutes per day, 5-6 days a week.  

In addition to that workout time, I make work and personal calls on them, and you can see how important they are in my everyday routine.  Little did I know at the time that my AirPods were about to be shelved entirely as the Sennheiser Momentum True Wireless 3 has a quality of sound that vastly outperforms the AirPods in every single way for about $60 more in price.  

With a spacious, dynamic, detailed quality of sound, the M3 true wireless, as I will refer to them in this article, have a very addictive quality of sound that is great for listening to music of all genres, watching YouTube videos, making phone calls or chatting via Zoom for work.

I didn’t realize how much more I would enjoy listening to earbuds with noise-canceling tech built-in until I got ahold of the Sennheiser’s.  Everyday activities such as running or walking my dog in windy Northern Nevada became much more enjoyable thanks to the active noise canceling and wind noise canceling of the Momentum True Wireless 3 earbuds.

I work out at a couple of local gyms when not training at home, one of which is Crunch Fitness, and the music at that gym is generally pumping loud, as is the clanging of weights and iron on the gym floor. 

In the past, I was subject to hearing all of this to some extent with my Apple Airpods.  With the M3 True Wireless, a simple click of the easy-to-use Sennheiser App or tap of the earbud and noise-canceling becomes engaged, giving me a quiet, more enjoyable listening experience while I train. I like to think this allows me to focus better on lifting and making gains in the gym.

So, I will tell you right now before we get into some of the build quality, comfort, and tech specs these are the best-sounding true wireless earbuds I have heard at this price, and I have only used my apple AirPods once or twice since having them and only when the Momentums were charging.  I like them so much that I am not sending them back to Wayne at TSAV, and I am buying them.   

Build Quality and Specs

The Momentum True Wireless 3 has an FR of 5Hz to 21Khz with a 7mm Dynamic TrueResponse transducer.  Their SPL is 107db per 1mW with a THD of less than .08%.  The FR of the microphones is 100hz-10kHz with a total of six Mics, three per earbud, which use the MEMS microphone principle with beamforming for noise reduction.

The built-in battery is rechargeable lithium-ion for both earbuds and the small travel charging case in which they live when not in use.  According to Sennheiser, the earbuds allow for 7 hours of operating time, with the charging case having 28 hours of running time.

Charging time is approximately 1.5 hours for a full charge, or if you are in a pinch and forget to charge but need to take an important work call or smash a workout, you can charge them for about 10 minutes and get 1 hour of music playback.

The M3 True Wireless uses Bluetooth 5.2 with several Bluetooth profiles and Audio Codecs, including SBC, AAC, aptX, and aptXadaptive.  As I mentioned, they use Active Noise Cancellation by Hybrid Adaptive ANC and have an IPX rating of IPX4 for splash resistance.  The case, however, does not, so you should keep it dry and clean.

The weight of the earbuds is 5.8g, and I found them to be comfortable for earbuds.  Like all earbuds or earphones, it will take a bit to get the seal right, and the M3 True Wireless includes four sets of Silicone ear adapters Xtra Small, Small, Medium, and Large. 

They also include Small, Medium, and Large Ear fin sets, which are great so you can better retain the earbuds in your ears when working out or sweating.  You also receive a quick start guide and an incredibly easy-to-use app that can be downloaded for IOS and Android.

Sennheiser Smart Control App

Once you download the Sennheiser Smart Control App, you can keep the earbud's firmware up to date and fine-tune the sound you are going for with its integrated equalizer, several presets, and guided listening test.

As I mentioned, you can also control the active noise canceling via the App, seeing the battery life of the earbuds and the charging case. You can turn on and off transparency mode via the app or use the touch controls and tap the left earbud once to pause the music and turn on transparency mode, which works great when someone is training their Jaw at the Gym and tries to talk to you so you can hear what they are saying.

Speaking of touch controls on the left earbud, if you tap twice, you go to the previous track, three taps turn on noise cancellation, and holding turns the volume down.  On the right earbud, tap once is your play and pause button; tap twice to skip to the next track; three taps is your voice assistant, and hold is volume up, which all work very well in my experience.

If this sounds complicated, I promise it isn’t, and it becomes second nature after using them for a bit.  If you forget, no biggie, pop open the app and go to touch controls, and it will tell you everything I just did, and it's always with you on your phone if you forget.

You can even create sound zones via the app, which automatically applies your sound settings when entering or leaving zones such as your office, the gym, or around the house.

Getting them set up on my iPhone and Macbook Pro was a breeze, and I am happy overall with the Sennheiser app; it has come a long way since I last used it with my old Momentum True Wireless 2’s. 

Sounds Impressions

Ok, so let me go through the sound quality briefly in a little more detail.  I will give you a general overview of the sound as I don’t have other true wireless earbuds of this caliber to compare them to; however, based on the popularity of this article, maybe I will ask Wayne to send me some others from the store to compare for future articles if you guys want, so don’t forget to smash that like button and share this article with friends.

Most of my impressions are based on listening via Tidal and Qbuz via Roon ARC via my iPhone.  Starting with Bass, the Momentum True Wireless 3 has great bass, with excellent sub-bass and mid-bass performance.  The bass is full, reasonably tight, fairly detailed, and punchy, making jamming to electronica, metal, pop, and rock an absolute joy.

The midrange is Sexy Sennheiser with superb attention to strings and vocals with just a touch of warmth and body in all the right places for my preferences without too much forwardness in the wrong places allowing for a fatigue-free listening experience.

Treble is present, with good air and definition, ensuring cymbals have plenty of presence and splash without sounding overbearing, fatiguing, or artificial.

Their Timbre is good sounding, natural, and enjoyable, with a soundstage that is quite impressive for a $249 set of True Wireless earbuds allowing for easy separation of instruments from vocals and good imaging with a spacious quality of sound that is very believable.

Dynamics are great, as I have begun to expect from Sennheiser after hearing some of their most recent earphones.  They punch and slam when called on, giving a good sense of emotion from the instruments being played, and they easily keep up with dynamic shifts in the music. 

So, what is not to love?  Sorry but at this price, I honestly can’t find much to fault for my preferences.  I suppose the charging case could be smaller, but I am stretching to find something somebody might complain about.  

If you are a treble head and like super bright-sounding earphones, then these probably won't be your cup of tea; however, if you like a weighty warmer bass region, a detailed and Sexy Sennheiser midrange, and an unfatiguing treble region, these could be a good fit for your everyday carry true wireless earbuds!  If their sound out of the box isn’t perfect for you, you can easily adjust their sound signature with the app's built-in equalizer.

As always, I encourage you to listen to them to formulate your impressions, as we all differ on what we value or prefer in sound quality.  If you are in SoCal, you can always pop by our headphone bar and give them a listen and compare to a few other options as well.
