Sennheiser’s new Momentum True Wireless 2 earphones are among the priciest pairs of wire-free earbuds we’ve tested. For $299.95, you get some of the best audio performance we’ve heard in the category, with solid bass depth and high-frequency clarity, as well as the ability to dial in your own EQ settings to taste. You also get terrific active noise cancellation (ANC), arguably on par with Apple’s class-leading $250 AirPods Pro. That makes the Momentum True Wireless 2 an excellent pair of earphones for audiophiles seeking strong ANC and even better audio performance.
The earphones are available in black or white, with metallic outer panels emblazoned with the Sennheiser logo. The earpieces are chunky but light, and twist into a secure fit easily. Sennheiser includes a total of four pairs of silicone eartips; otherwise the earpieces lack any extra fit appendages, like fins. Internally, the earpieces house 7mm dynamic drivers that deliver a frequency range of 5Hz to 21kHz.
The earpieces have an IPX4 rating, which means they have a modest amount of protection against moisture. They can handle light splashes and should be fine for sweaty exercise or light rain, but running them under the faucet to clean them is not advised, as they can’t handle much water pressure. If water resistance is a top priority, you may want to opt for earphones with a higher IP rating, like the Jabra Elite Active 75t or the Jaybird Vista.
The outer panels of the earphones are sensitive to touch and even make an audible beeping response when pressed or tapped. The controls are divided between the two ears, with the left earpiece handling playback (one tap), track forward (two taps), track backward (three taps), and volume down (hold). The right earpiece controls voice assistants (one tap), transparent listening mode (two taps), ANC on/off (three taps), and volume up (hold). It’s odd that Sennheiser chose to divide some controls between the two earpieces (like volume) but not others (like track navigation), which makes memorizing their functions a little harder than usual. It’s also a bit too easy to accidentally summon your phone’s voice assistant or press play when putting the earphones in your ears.
The charging case is compact, with a flip-top lid and a gray canvas contour. Its back panel houses a USB-C port for the included charging cable, as well as a status button that shows how much charge is available when pressed. Sennheiser estimates battery life to be up to 7 hours on a full charge, with the charging case carrying an additional 28 hours, but your results will vary with your volume levels and your use of ANC.
The Sennheiser Smart Control app (for Android and iOS) easily connects with your paired earphones and allows for customization of the on-ear controls. You can choose whether music continues to play in transparent listening mode, for instance, or assign call management controls, like call reject, to either ear. You can also adjust how much of your own voice you hear during calls, whether Smart Pause (which pauses audio when one earpiece is removed) is active, and whether you auto-accept calls, a feature that automatically answers calls when the right earpiece is removed from the charging case. Best of all, the app has adjustable EQ that works well for adding in some extra bass or treble, or cutting the mids, for instance.
The earphones are compatible with Bluetooth 5.1, and support AptX, AAC, and SBC Bluetooth codecs.
The earpieces already do a decent job of sealing off the ear canal and blocking outside noise, but combined with the ANC, the results are strong. Low-frequency rumble, as you’d hear on a plane or train, is tamped down significantly, as are mid-range sounds, which can take a lot of the body out of music being played nearby, or office chatter.
The earphones don’t seem to add much audible hiss to the equation, which is another sign of quality ANC. And finally, the ANC seems to have little or no effect on the audio performance—bass doesn’t sound deeper with it on or off. The transparent listening mode is also very useful, allowing you to easily monitor your surroundings and hear yourself talking without removing the earpieces.
We tested audio performance with the EQ set to default flat mode. On tracks with intense sub-bass content, like The Knife’s “Silent Shout,” the earphones deliver a powerful low-frequency response. At top, unwise listening levels, the lows don’t distort, and at more moderate volume levels, there’s still a strong, palpable sense of bass depth. The lows are well balanced with the highs so that things don’t become muddy or overly bass heavy.

Bill Callahan’s “Drover,” a track with far less deep bass in the mix, gives us a better sense of the general sound signature. The drums on this track can sound too thunderous on bass-forward in-ears, but here they sound natural—full, but not super heavy. Callahan’s baritone vocals get a solid amount of low-mid richness, paired with some nice treble edge to keep things crisp and clear. The tape hiss on this track jumps a little bit forward in the mix, telling us there’s a bit more high-frequency presence, and the acoustic strums and higher-register percussive hits get a clear, crisp response, as well.
What’s notable is that the mids feel quite present as well—many sound signatures we hear are often scooped, with big bass and bright highs but not much connecting the two. Here, the mids feel full and bridge the solid bass depth and the bright highs. This is a sculpted sound signature, but less so than many we hear in true wireless in-ears, and far more balanced than most.
On Jay-Z and Kanye West’s “No Church in the Wild,” the kick drum loop receives enough high-mid presence to retain its punchy attack, while the vinyl crackle and hiss that is usually relegated to background status steps forward a bit in the mix. The sub-bass synth hits that punctuate the beat are delivered with solid, unexaggerated depth—you hear them and sense their ominous, deep bass presence, but it doesn’t overwhelm the mix in the slightest. The vocals on this track are delivered with excellent clarity and no additional sibilance.
For orchestral tracks, like the opening scene from John Adams’ The Gospel According to the Other Mary, the lower-register instrumentation get a slight push forward in the mix, without overwhelming the balance. The higher-register brass, strings, and vocals still retain their bright, prominent place. Once again, if there’s anything we notice, it’s the presence of mids in the mix—it allows the orchestra to sound full and natural rather than sculpted with only deep bass and bright highs.
The mic offers solid intelligibility. Using the Voice Memos app on an iPhone 8, we could understand every word we recorded. There was still some Bluetooth distortion fuzzing up the edges of the recording, but the mic signal was strong and there was even a solid amount of low-mid richness in the mix.
The Sennheiser Momentum True Wireless 2 earphones deliver effective ANC, fantastic audio performance, and a useful app. They’re among the best true wireless models you can buy, though at $300, they’re also among the most expensive. If you’re looking to spend less, it’s hard to argue against the aforementioned $200 Jabra Elite Active 75t and the $250 Apple AirPods Pro, both of which deliver excellent features and strong audio performance for less money. And if you don’t need ANC and are on a tighter budget, we’re also fans of the $80 Anker Soundcore Liberty Air.
