1more Dual Driver BT ANC

Practice

The soft neckband and rear magnetic earplugs provide good wearing comfort. The generous addition of nine pairs of different ear cushions (both silicone and foam) allows you to find the right size and shape for your ear canal so that a good fit and seal are also guaranteed. The controls are located on the left side of the neckband. These include the on/off switch (which also initiates the rapid pairing), a second slide switch for configuring the noise cancelling, a button for starting and stopping the music playback (which can also be used to jump forward and back with a double or triple click), and a rocker switch for volume control. The control elements are well defined by their shape so that a “blind” function selection is safe and easy with a little practice. The functionality is supported by vocal confirmation, but this is dull. Contrary to the supplied documentation, the device doesn’t currently support language assistants, but this could, according to the manufacturer, be changed by a firmware update.

A full charge of the battery lasts for seven hours (charging time: 1 hour). However, a quick charge function can achieve three hours of playing time in just ten minutes. In addition, the Dual Driver BT ANC can also be used in cable mode, but only actively, so you still have to pay attention to the battery level.

Noise Cancelling

The active noise cancelling complements the rather medium passive isolation of the earplugs. The two-stage switchable electronics work with a fixed intensity, but the impact is comparatively moderate; happily, there is no disturbance from the glass bell effect. Static is suppressed, especially at low frequencies, so that when travelling on a train or plane – or in a quiet environment – enjoyment of the music is enhanced through an improved noise-to-noise ratio. This also provides a quietness even without music, although voices and other irregular noises do penetrate the protective barrier. Noise cancelling can also be used in cable mode.

A special feature of the design is that the Balanced Armature driver is not included in the active noise reduction because it works in the high-frequency range. Accordingly, there are no losses with regard to transparency and detail resolution.

As an alternative, ambient noise can also be deliberately fed into the drivers via the external microphones to improve communication. The switchable interaction with the environment generates a frequency-specific tunnel, which practically improves communication and intelligibility. In return, however, you will have to accept a clearly perceptible background noise.

Sound

As always, the choice of the right earplugs is a prerequisite for the best possible sound impression. The Dual Driver BT ANC works with Bluetooth 4.2, while the supported Bluetooth audio codecs are not mentioned in the specifications. When asked, it was found that only SBC is used under iOS AAC and Android; this is in clear contrast to the LDAC-capable, more expensive Triple Driver BT model. The hearing test was done with an iPhone 8S via Bluetooth with Noise Cancelling switched on.

The result is impressive, because the drivers deliver a balanced, detailed sound. The level reserves are also sufficient for mobile use, with good external noise attenuation.

In the bass range, the Dual Driver BT ANC reaches deep down and delivers the necessary dynamics and tonality at the same time. The low bass reproduction is surprisingly well defined and only reaches its limits at higher volumes. The bass range, in general, is not uncomfortably overemphasised, but undoubtedly delivers the necessary pressure in mobile use.

I particularly like the midrange reproduction, which organically combines with the bass range and gives synthetic basses and percussion a “fleshy” character. Whether rock or dynamic classic, the earphones manage the balancing act between powerful reproduction, authenticity and intimacy. Voices and solo instruments have the necessary high-mid range.

In the higher frequencies, the BA driver provides good transparency, which also ensures high detail resolution and good stereo and room imaging. I couldn’t find any disturbing hardness. An all-round positive sound result, considering the price range and the area of application. By audiophile standards, I would have preferred more openness. Finally, the telephone function provides a sufficiently good speech intelligibility in both directions, but here, it’s slightly lacking in transparency.
