About the Sennheiser Momentum True Wireless 4

Jeff Miller

The latest in Sennheiser's sonically focused wireless earbud legacy

The Sennheiser Momentum True Wireless 4 earbuds certainly have big shoes to fill. Each of the three previous-generation Momentum TW models were named our "best-sounding" wireless earbuds. Based on my very early impressions, Sennheiser is very much up to the task. They've made small refinements to the (already top-tier) drivers and sound tuning of the Momentum TW 3s, while adding some cutting-edge wireless technologies.

The latest in Sennheiser's sonically focused wireless earbud legacy

The Sennheiser Momentum True Wireless 4 earbuds certainly have big shoes to fill. Each of the three previous-generation Momentum TW models were named our "best-sounding" wireless earbuds. Based on my very early impressions, Sennheiser is very much up to the task. They've made small refinements to the (already top-tier) drivers and sound tuning of the Momentum TW 3s, while adding some cutting-edge wireless technologies.

My early impressions

I haven't had much time with the Momentum TW 4s, but they look very similar to their predecessors and feel more comfortable to my ears. I found the ear tips were softer and better avoided pressure points – specifically in my left ear. They also create a nice, secure seal to help the effectiveness of the noise cancellation – which is strong and well-above average for earbuds.

As for the sonic performance, I heard the familiar nuance and well-defined sense of place that I expect from Sennheiser earbuds. I'll have deeper listening impressions soon, but I was struck by the full, controlled bass and a midrange that's delightfully prominent without being too forward. The highs are smooth yet articulate enough that they don't sound unnatural. Overall, they gave me a very pleasant and engaging first impression.

Strong, high-quality wireless audio

Music plays wirelessly via Bluetooth 5.4 — a newer, reliable version of the popular wireless technology. WIith a firmware update, these earbuds support Bluetooth LE Audio, which is a leap forward for sound quality. It allows for lossless streaming with compatible devices.

Also included is aptX™ Adaptive technology. This versatile wireless audio codec automatically detects if you're in an area with competing Bluetooth signals, and it will optimize either reliability or sound quality accordingly. It can also sense when you're watching a video on, say, Netflix or YouTube, and keep latency low. So, the audio and video should be better synced up.

Features

Overview: The Sennheiser Momentum True Wireless 4 (MTW4) in-ear headphones are two individual ear buds with no connecting wires. They connect to your smartphone or tablet (and to each other) via Bluetooth 5.4. Four pairs of silicone ear tips (XS, S, M, L), and three pairs of silicone ear fins (S, M, L) are included for a secure and comfortable fit. The headphones are equipped with Adaptive Noise Cancellation (ANC) to shut out the outside world while you listen to your music or phone call. Cutting edge technology such as Auracast™ broadcast audio and LE Audio's LC3 codecs are available via a firmware update. The Momentum True Wireless 4 headphones come with a charging case for storage, and for recharging the batteries.

Drivers: The True Wireless 4 ear buds feature 7mm TrueResponse™ dynamic drivers that reproduce a wide frequency range and provide the Sennheiser Signature sound. From the crystal clear highs to the natural midrange and low bass, you can enjoy your favorite music from any genre. You can tailor the sound of the earphones through the equalizer found in the Sennheiser Smart Control app, available for iOS and Android devices.

Bluetooth 5.4: The Momentum True Wireless 4 headphones feature Bluetooth version 5.4 which pairs to your phone or audio device in seconds. The ear buds can pair with up to six Bluetooth devices, and make up to two active connections simultaneously (multi-point). You can make and receive phone calls and stream audio wirelessly in a range of up to 33' (10 meters), depending upon environmental conditions. The headphones have a maximum of 10mW of output power, and have the following profiles: HFP, AVRCP, A2DP, TMAP, and PBP. The headphones support aptX and aptX Adaptive/Lossless/Low Latency, as well as AAC (advanced) and SBC (standard) codecs. With a firmware update, available through the Smart Control app, you can load new features, including Auracast™ broadcast audio and LE Audio's LC3 codec. Either the right or left ear bud can be used alone, if desired.

Auracast Broadcast Audio: Auracast technology allows an audio signal from a transmitter to be transmitted to an unlimited number of receiving devices located within a fixed transmission radius. This allows audio from certain TVs, public address systems, and tour guide systems in museums to be heard in your ear buds. The Smart Control app lets you select a nearby Auracast channel and play it through your ear buds.

Active Noise Cancelling (ANC): Each ear bud is equipped with three microphones, two on the outer panel and one on the inner panel, for Active Noise Cancellation. Tapping the left ear bud three times activates (and deactivates) ANC. The noise cancellation is "adaptive," with the maximum noise reduction occurring in a noisy environment, and the minimum in a quiet environment. There is also an "Anti-Wind" feature to reduce ambient noise caused by windy conditions. The Transparency Mode lets you hear ambient sounds or have a short conversation without having to remove the ear buds. In addition to the touch controls on the ear buds, you can turn on or off ANC and Transparency Mode in the Smart Control app.

Voice Assistants: The ear buds are compatible with the voice assistant that is native to your smartphone, such as Siri or Google Assistant. Tapping the right ear bud once activates the voice assistant for you to make a request or ask a question. You can also activate voice dialing through the voice assistant.

Rechargeable Batteries: The Momentum True Wireless 4 headphones are powered by built-in Lithium-Ion rechargeable batteries. Each ear bud has a 3.8V / 72 mAh battery, while the charging case has a 3.6V / 820mAh battery. The complete charging cycle of the charging case and earphones is approximately 1.5 hours. An 8-minute Quick Charge provides about 1 hour of playback time. The battery in the charging case charges via USB-C power (5V, 1000 mA) using the supplied cable from a laptop, an AC-powered USB charging port, or a mobile 12-volt USB charging port. The charging case is also compatible with Qi wireless charging (charging time is slightly longer). Fully-charged batteries in the ear buds provide approximately 7.5 hours playback with ANC off, and 7 hours playback with ANC on. The charging case provides enough stored power to charge the ear buds 3 additional times, to extend the playback time to 30 hours.

Phone/Music Controls: Touch Panel controls for music playback and phone call functions are located on the outside of both ear buds. Various touch patterns can also activate ANC, Transparency, Voice Assistant, and Volume.

Smart Pause: The ear buds automatically detect when they are being worn, or when they are removed from the ear. When you remove one of the ear buds from your ear, the Smart Pause function pauses the music automatically. The music automatically resumes if you reinsert it within a minute. You can turn this feature on or off in the Smart Control app.

Voice Prompts: The ear buds provide a voice prompt to confirm certain functions and conditions. Voice Prompts include subjects such as Power ("Power On", "Power Off"), Bluetooth ("Connected", "Pairing", "Pairing cancelled/successful/failed"), Battery Status ("Battery Status" (percent), "Recharge headset"), Phone Calls ("Call Rejected", "Call Ended"), and Volume ("Volume Minimum", "Volume Maximum"). On the Smart Control app, you can change the language of the prompts (8 languages available), choose between voice prompts and beep sounds, or deactivate the status messages.

Smart Control App: In addition to the on-board controls, the Momentum True Wireless 4 in-ear headphones can be controlled by Sennheiser's Smart Control app for Android and iOS devices. The app lets you personalize and enhance the sound to suit your current mood with the easy-to-use equalizer. The Transparent Hearing function lets you adjust how much of your surroundings you can hear while wearing the ear buds. You can shut out your surroundings if you want to concentrate on your music, or allow ambient sounds in if you need to listen for announcements, or carry on a conversation with another person, without having to remove the ear buds. Firmware updates for the earphones are also available through the app, including those for Auracast and LE Audio. The Smart Control app is compatible with iOS devices (iPhone, iPod touch) running version 13.0 and later, and Android devices with version 8.0 and up.
