Yamaha Launches TW-E7B True Wireless ANC Earbuds Featuring Large 10mm Drivers

Yamaha Corporation announced the launch of the new TW-E7B true wireless earbuds, sitting atop the brand's already extensive true wireless offering. Adopting Yamaha’s True Sound philosophy at the forefront of their design, with large 10mm drivers and acoustically optimized housings, the TW-E7B earbuds are for users wanting to truly immerse themselves in their favorite music, demanding superior sound quality while not compromising on the latest technology and convenient features. The new TW-E7B earbuds are now Yamaha's flagship true wireless earbuds, combining an Yamaha-exclusive's advanced ANC implementation combined with a powerful processing system that is able to correct the sound of the new large drivers in real time, adapting the response to the environment. Yamaha designed a new Listening Optimizer feature, an interesting concept that combines the advanced ANC features and Ambient Sound mode, adjusting the drivers response to leave music listening pure and untouched. The processing system also features what Yamaha names Listening Care, a dynamic loudness optimization feature for full-range sound at lower listening volumes. Both concepts make every sense in a design that features unique, large size drivers and is targeted at users that truly care about sound quality.

Otherwise, like most TWS designs these days, the new Yamaha TW-E7B earbuds leverage a Qualcomm Bluetooth platform, supporting Qualcomm cVc (Clear Voice Capture) for calls, combined with an advanced mic design, and stable wireless connectivity with Qualcomm TrueWireless Mirroring and role swapping features.
 
Other interesting features of the TW-E7B design include in-ear detection capability for automatic start/stop of music and app control, and a Gaming Mode that reduces the delay between sound and video, optimizing performance for gaming use and video content. 

As Yamaha details, True Sound is Yamaha’s promise of bringing the listener ‘closer to the artist,’ achieved through a variety of features and technologies – acoustic and electronic. "Achieving the fundamental objective of True Sound is based on three key elements: Tonal Balance, Dynamics and Sound Image. Through the acoustic and electronic technologies, the TW-E7B realizes music reproduction that combines high-resolution sonic timbre (Tonal Balance), rhythmic and deep musical lows (Dynamics), and naturally enhanced spatial expression (Sound Image)," the company explains.
 
The Design
Unconventional for a true wireless earbud, the TW-E7B employs a large 10mm driver unit with a large-diameter voice coil, realizing truly musical low-frequency reproduction. The diaphragm is highly responsive, accurately reproducing tonal qualities with particular sensitivity to the dynamic lulls and rises in the sound. Unnecessary vibrations and echo interferences have been minimized due to the housing design, delivering clear high-frequencies and excellent spatial expression. Air inside the IPX5 (water and sweat resistant) housing is carefully controlled with ‘leak-holes’ on the front and back of the driver housing, efficiently maximizing the performance of the driver unit.

To ensure comfort over lengthy listening periods and also to minimize sound leakage - improving low-frequency sounds and overall audio accuracy - the mechanical design of the TW-E7B was studied to minimize pressure on various parts of the ear, reducing wearing fatigue over long listening periods. Further, the elliptical design ensures a comfortable fit for different ear shapes, simply by rotating the earbud into the most comfortable position. In addition, the 5 different ear-tip sizes provides a tight yet comfortable fit, ensuring full frequency reproduction over extended listening periods, with low levels of fatigue.

And understanding that every ear is different and that the left and right ear of the same user have different characteristics, Yamaha analyzed how those differences affected the overall sound balance of the earbuds. The new Listening Optimizer feature analyzes and corrects the effects of individual ear shapes and wearing in real time. The TW-E7B uses an internal microphone which monitors the signal affected by the shape of the ear canal and how the earbud is worn, calculating the difference from the original audio signal, and finally correcting the difference so that it can deliver on the promise of True Sound. Otherwise, the TW-E7B earbuds also allow users to adjust the EQ individually with the new Headphone Control App. Yamaha’s own unique algorithm is also employed on the TW-E7B with a focus on retaining the nuances of the music while blocking out external noise. Traditional ANC uses an internal mic to listen to noise in the ear canal. However often the sound in the listeners’ ear canal also includes music, which is then also at risk of also being suppressed. Traditionally, earbuds apply EQ corrections to the music signal in advance, raising the low-frequency level that is likely to be compressed. This can however degrade the audio by applying unnecessary processing of the sound. Yamaha’s propriety algorithm analyses the signal received from the internal mic and the playback music signal, calculating and filtering noise components, then finally separating the noise component, leaving the music signal untouched. Now a trademark of Yamaha headphones and earphones, Listening Care acknowledges Yamaha’s promise of safe listening practices for a lifetime. Listening Care balances the difficult-to-hear high and low frequencies during low-volume listening so that the original balance of the music is maintained. The TW-E7B earbuds offer Listening Care – Advanced, which factors in Content Volume (such as the dynamic range of the music and the different recording levels) and Surrounding Noise (the level of external noise which, if high, can overwhelm the music requiring the user to increase the earbud volume) to deliver the optimal sound at any volume. Listening Care – Advanced has been designed to support and encourage safe listening practices, encouraging users to think about their long-term hearing health.

According the Yamaha, even with the large drivers, all the sophisticated ANC and processing features, the TW-E7B True Wireless ANC Earbuds are able to achieve up to 6 hours of listening with ANC turned on (+ 16 hours from the charging case). The in-ear detection and convenient buttons offer simple control of the earbuds' main features, while the Headphone Control app offers extended features including turning Listening Care – Advanced on or off, and access to EQ adjustments.

The Yamaha TW-E7B TWS earbuds are now available and retail for $299 USD.
