The Sennheiser Smart Control app is available for both Android and iOS smartphones
The Smart Control app also allows users to save certain sound settings based on the different locations that they frequent, like the home, gym, work, cafe, etc. This requires access to the connected phone’s location. Essentially, for each sound zone, you can save a particular combination of noise control and equaliser settings. These can be saved for both “entering” and “leaving” the zone. What is the zone? You can define it by starting from 100m to up to a 1km radius of a particular point on the map. With your location access permission, these settings will automatically be applied to your music/podcast as you commute in and out of the pre-decided sound zones.
The Sennheiser Accentum TWS earphones come with 7mm TrueResponse transducers and support Bluetooth 5.3 multi-point connectivity. They also support SBC, AAC, aptX, and LC3 codes and Hybrid Adaptive ANC. Each earbud is equipped with two mics and a 55mAh battery, while the charging case, with a USB Type-C port at the bottom, packs a 400-420mAh battery.
Sennheiser Accentum True Wireless Review: Performance and Battery Life
As previously mentioned, the Sennheiser Accentum TWS earphones come with many noise cancellation modes as well as transparency levels. These modes are powerful and deliver what their names promise. The active noise cancellation mode manages to drown out almost stray sound. If you need some quiet time to finish work or to seek solace amongst snoring housemates, this is a good pick. The different transparency levels are, of course, useful for the outdoors. Since this mode allows environmental disturbances to follow through to help users stay alert, the sound quality is also affected by this.
The ANC mode, however, leaves the sound experience largely undisturbed. Alongside the bass boost and podcast modes, the Smart Control app holds seven equaliser presets — Rock, Pop, Dance, Hip Hop, Classical, Jazz and Movie. The sound experience in each of these modes is gratifying, to say the least. Having transitioned from always playing some of my favourite music on my regular budget TWS earphones, the exposure to the audio quality of the tracks using the Accentum TWS earphones was truly delightful.
Each Sennheiser Accentum TWS earbuds weigh only 5.5g
I tried to cover a wide array of genres and musical tones and played around with the custom equalisers as well as the presets. From Moondance by Van Morrison to Slow Dancing in the Dark by Joji, from Killer Queen by Queen to Outro: Tear by BTS — there was never a track I found which fell flat with these Sennheiser Accentum TWS earphones. For me, the testament to the sound experience these earphones offer was locked in when I played I Want You (She’s So Heavy) by The Beatles. Exhilarating. The track itself is arguably one of the best and earliest prog-rock mixes of all time. With these audio wearables, the timbre of that music is only accentuated. From all my years of marvelling at this Lennon–McCartney gem, this is the clearest and most detailed listening experience I have had of the track.
The multipoint connectivity feature of the Sennheiser Accentum TWS earphones operates smoothly. They were connected to a smartphone and a laptop simultaneously at almost all times. Switching from the audio of one of the devices to the other was seamless in my experience.
The call quality the earphones offer is also good. However, the mic is not the best. It is not at par with the sound experience. Although this is not that surprising, considering the earphones lack stems, and then by design, the microphones are placed higher up inside the individual buds. Personally, this took very little away, if at all any, from my experience of the earphones since I am not big on calls to begin with.
What does stand out for me though, is the battery performance of the audio wearable. Without any noise cancellation features, the Sennheiser Accentum TWS earphones (when used with the aptX codec) offer a total battery life of up to 23 hours as opposed to the advertised 28 hours. The total battery life of the earphones alongside the charging case falls to up to 21 hours with the active noise cancellation turned on. When used with the AAC codec, the earphones offer a total playback time of up to 24 and 22 hours, respectively, without and with ANC.
The Sennheiser Accentum TWS earphones are IP54-rated, but the charging case has no such certification
Just the earphones of the Sennheiser Accentum True Wireless are claimed to offer a playback time of up to eight hours on a single charge. With the aptX codec, the battery life of the earphones with and without ANC lasts for up to five and a half and up to seven hours, respectively. Using the AAC codec, they lasted for up to eight hours on a single charge without ANC and almost six hours with ANC. The earphones’ charging case supports USB Type-C wired and Qi wireless charging. Only 10 minutes of charge can offer users a playback time of up to an hour.
Sennheiser Accentum True Wireless Review: Verdict
The Sennheiser Accentum TWS earphones are retailing in India at Rs. 12,999. It is a handsome amount for TWS earphones but if your budget allows you, they are an easy pick. You get the sound experience you expect from a Sennheiser audio product. Paired with the Smart Control app, you can get an extensive equaliser personalisation control. The noise cancellation and transparency settings, including the anti-wind preset, do their job quite well. The lightweight earbuds and the compact charging case also qualify these earphones as one of the finest audio wearables in the market.
To get the Sennheiser Accentum true wireless earphones, though, you have to look past the battery life they offer. If you use a higher audio codec as well as the noise cancellation modes, the total playback time reduces to up to 23 hours. This may not objectively account for bad battery performance, given all the features, but it may be a deal breaker for some.
If you fall in the latter category, you may want to check out the Moto Buds+ (Review). They are priced in India at a lower Rs. 9,999 but are claimed to offer a total battery life of up to 38 hours. The Moto earphones also support LHDC Bluetooth codec and flaunt Bose-certified sound. Another pair you can look at, for a price of Rs. 11,999, is the Nothing Ear (Review) TWS earphones, which offer up to 40.5 hours of battery life as well as ChatGPT integrations.
