[Material evaluation] Sennheiser MOMENTUM true wireless generation 4 evaluation: more intelligent experience, more HiFi sound quality

Unconsciously, the fourth generation of Sennheiser MOMENTUM series real wireless headphones has been launched, and the official model MOMENTUM True Wireless 4 is still mouthful, so it is hereinafter referred to as MOMENTUM TW 4, which is convenient for everyone to read.

As a brand new flagship TWS headset product of Sennheiser, this time MOMENTUM TW 4 has further improved its noise reduction performance, sound quality performance, battery life and other aspects, and is also compatible with LC3, the new generation of Bluetooth standard LE Audio for the first time, achieving more efficient audio transmission efficiency. The sound quality performance is expected.

In terms of price, the official price of MOMENTUM TW 4 is 2199 yuan, slightly higher than the third generation's 1999 yuan. I have been using this headset for more than a week recently, whether for commuting, entertainment or office work. This article will talk about the overall use experience of MOMENTUM TW 4 with you in detail.

Appearance: inheriting the family style classic design

Since Sennheiser officially launched the first generation of MOMENTUM TW true wireless earphones in 2018, this series of products has always maintained its representative and highly recognizable design style - the charging box is made of cloth material, the headset has a round shape, the metal laser logo, etc. Among many TWS earphone products, it can be identified as Sennheiser's earphone at a glance.

In terms of color, in addition to the two classic colors, black and white, MOMENTUM TW 4 also added a retro gold color, which is a very low-key coffee gold. I personally like this new color, which is not too fashionable.

Wearing&operation: more comfortable and better use

In terms of wearing experience, the weight of a single MOMENTUM TW 4 earplug is 6.2g, 0.4g more than that of the previous generation. Although the weight is slightly increased, there is no significant difference in ear pressure; The reason why I am satisfied with the wearing comfort of MOMENTUM TW 4 is that each earplug is also specially equipped with silicone fins to ensure a secure fit for you.

You should know that the most critical point of many TWS earphones on the market is that they can not be worn (or even not worn), and the knowledge of this is that the friction of silicone earplugs alone is obviously not enough to support large movements in sports. Therefore, if you want to wear headphones firmly, you need more support points.

On the MOMENTUM TW 4, a set of fins is specially equipped for the headphone cavity (the previous generation products are also equipped), and three sizes of S/M/L are provided; Its function is to become the third supporting point outside the earplug sleeve and earphone cavity shell, forming a three-point fixed structure design scheme, which greatly improves the wearing stability. Together with the four sizes of XS/S/M/L silicone earplug sleeves, it is easier for users with big ears, small ears or "wooden ears" to find a comfortable wearing experience.

For me, this is also true in daily use: wearing MOMENTUM TW 4 to jog in the park or perform functional strength training at home, the earphones are firmly worn throughout the whole process, which is not easy to loose and fall off, so there is no need to frequently straighten the earphones, and daily use is relatively easy.

When it comes to daily sports, MOMENTUM TW 4 earphones have IP54 dust-proof and waterproof protection, which is better than the previous generation of products. They can prevent the splash of sweat, rain and other liquids, and have new dust-proof performance, which can meet the use requirements of more sports scenes, such as outdoor long-distance running, cycling and so on.

In terms of operation, just like the third generation, the cavity shells of the left and right MOMENTUM TW 4 earphones are equipped with capacitive touch buttons, which can control music playing/pausing, noise reduction/transparency mode switching, answering calls, adjusting volume and other functions through finger actions such as clicking/double clicking/triple clicking/pressing.

However, the main thing to note is that due to the different touch key functions on the left and right headphones, the old users of the MOMENTUM TW series are fine. If they are new to the MOMENTUM TW 4, they may need to adapt for some time. Of course, users can also customize the touch control of left and right headphones in the "Smart Control" app according to their own usage habits.

Noise reduction: more intelligent noise reduction performance

As the new flagship TWS noise reduction headset of this series, MOMENTUM TW 4 has three microphones installed in each earplug (the number is the same as that of the previous generation). Two microphones are located on the outside of the headset, while the other is facing the ear canal, and then the beam forming technology is used to reduce noise to obtain clearer voice call quality. This is also the mainstream noise reduction scheme adopted by most flagship TWS earphones at present Voice Assistant The interaction can also achieve better results.

For daily use, I wear MOMENTUM TW 4 to make voice calls in a noisy environment such as a subway station, and the voice of the headset can still be clear. In the windy outdoor environment, the earphone microphone can correctly identify the wind noise. As long as it is not against the wind in a strong wind above level 5 or 6, the voice heard by the other party will be relatively quiet.

In addition, the "Smart Control" app also provides a wealth of noise reduction options, and the new generation hybrid adaptive noise reduction performance adopted on MOMENTUM TW 4 has also been improved to ensure that you can hear voice broadcast alerts such as subway station announcement while shielding external noise.

In fact, it is not difficult to understand that the advantage of adaptive noise reduction technology is that it can automatically adjust the noise reduction level according to the environment, especially in a quiet environment, so that the maximum noise reduction depth will not cause discomfort and pressure on the ears.

When playing with music, MOMENTUM TW 4 allows me to better immerse myself in the music world. Especially in the subway environment with complex background sounds, I can still get a comfortable and quiet sense of listening. At the same time, the sound performance does not affect the balance of three frequencies and the delicacy of high frequency due to the blessing of active noise reduction.

When you need to hear the surrounding sounds or talk, tap to open the low-noise transparent listening mode, so that the world can return to the ear, and at the same time, it can significantly reduce the blocking effect of the headset, and instantly present natural and clear environmental sound. The transparent listening mode also provides three levels: low, medium and high. Users can manually adjust it to the most comfortable and natural listening feeling.

In addition, the APP also provides a set of "sound area" automatic adjustment mode (you need to obtain your mobile phone positioning permission). When the headset enters a certain area with the user, the preset operation can be triggered. For example, when I enter the office building of the company, the earphone can automatically turn off noise reduction and turn on the transparent mode, and the preset equalizer will change accordingly. The map range setting is also very intuitive, which is easy to use for the first time.

It is worth mentioning that MOMENTUM TW 4 also supports the new generation of broadcast audio AURACAST this time. Its working principle is simple, just like you usually search Wi Fi network or Scan QR code It is also easy to join, connect your device and receive radio. This new technology is expected to change the way we experience audio and connect with the surrounding world in the future, for example, connecting to public radio, television broadcasting or assisted listening (improving the audio accessibility in public places to avoid missing the train station announcement).

Sound quality: High resolution audio support, more HiFi sound performance

MOMENTUM TW 4 adopts the TrueResponse ultra wideband transducer system which Sennheiser is proud of, and is equipped with a 7mm dynamic coil drive Unit, frequency response range 5Hz - 21KHz, sound pressure level 107dB SPL (1kHz/1mW). The new upgrade also includes aptX Lossless lossless Bluetooth audio transmission and 24bit high resolution audio. In addition, MOMENTUM TW 4 also adopts a new generation of Bluetooth standard LE Audio, which the author mentioned earlier.

At the same time, the MOMENTUM TW 4 also uses the latest Bluetooth 5.4 technology, supporting SBC, AAC, aptX, aptX Adaptive/Lossless, LC3 Bluetooth audio editing decoder , ensuring wider coverage in terms of compatibility for high quality audio transmission.

Specifically, MOMENTUM TW 4 has a balanced low, medium and high frequency performance. The low-frequency part has a strong impact and sense of rhythm, and the sense of volume is moderate without a bang; At the same time, the separation between voice and instrument is orderly. When listening to pop music and classical music, the sound level is very clear, which can be said to reflect the strong Sennheiser style.

Taking Faye Wong's Shadow as an example, the jazz drum performance in the prelude to the song and the crisp sweep rhythm of the wooden guitar were all vividly interpreted by MOMENTUM TW 4. When the voice of the voice sounded, Wang Jingwen's melodious and slightly ethereal voice floated in, accompanied by the decoration of the guitar's broken chords, the euphemistic melody echoed with the voice of the voice, making people intoxicated.

Next is the main song of Tate McRae's new album "Think Later", "Greedy". The voice of the girl born after 00 was amazing when she opened her mouth, and the mid-range performance that MOMENTUM TW 4 is best at is also very "ear scratching". In addition to the optimization of low-frequency response, the Hip Hop and other popular melodies in the whole song are filled.

In general, MOMENTUM TW 4 is very good at controlling the female voice, hip hop and pop rhythm. At the same time, the performance of MOMENTUM TW 4 is also commendable in the grasp of percussion strength such as jazz drums and hand drums.

The equalizer adjustment of MOMENTUM TW 4 has also been optimized this time, bringing a new adaptive 5-segment equalizer. For users who like to calibrate their audio experience through the equalizer shown in the figure, the sound of MOMENTUM TW 4 can be adjusted through the 5-segment equalizer. The new equalizer can adapt to the loudness of audio content, and its advantage is to ensure that the sound can achieve better matching regardless of the volume.

The "voice personalization" provided in the app improves the playability of the headset by one step: after wearing the headset, you will hear three sounds of a song (strings, bass, drums), and then you need to adjust the volume balance of different bands and instruments according to your personal preferences. After several screening, you will get a sound tuning style that is more suitable for your listening preference. Playability is very high, and after adjustment, the sound performance of the headset really meets my preferences.

Write at the end:

From the perspective of iteration, Sennheiser MOMENTUM TW 4 is a new intelligent upgrade of the brand's flagship true wireless product series, integrating new connection technology, adaptive noise reduction, intelligent scene switching, and better performance of high-resolution audio. Although the overall appearance design has not changed much, the interior of MOMENTUM TW 4 has brought obvious upgrades. To sum up, the new generation of MOMENTUM TW 4 has become easier to use and sounds better. The price of 2199 yuan is really not cheap, but it still has strong competitiveness among the TWS flagship earphones of the same level, and it is worth the price in terms of product strength.
