Motorola Signature 27 brings Bang & Olufsen sound to flagship phones

Motorola’s Signature 27: A New Direction for Mobile Audio

Motorola has announced the Signature 27, a flagship model that marks the company’s first collaboration with Bang & Olufsen for audio tuning. The partnership aims to deliver a listening experience that rivals dedicated music players, while the phone retains the practical features expected from a modern smartphone.

Design language and build quality

The Signature 27 follows Motorola’s recent design cues with a sleek glass front, aluminum frame and a matte finish that reduces fingerprints. The device measures 158 mm in height, 71 mm in width and 8.2 mm in thickness, making it comfortable to hold despite a 6.7 inch OLED display. The screen supports a 1440p resolution and a 120 Hz refresh rate, offering smooth scrolling and vibrant colour reproduction.

Motorola has also introduced a new colour palette that includes a deep midnight black and a muted bronze tone. Both finishes are protected by Corning Gorilla Glass Victus, which provides resistance to drops and scratches.

Audio hardware and Bang & Olufsen partnership

At the heart of the Signature 27’s audio system are dual stereo speakers that have been calibrated by Bang & Olufsen engineers. The speakers feature a custom‑tuned diaphragm and an acoustic chamber designed to minimise distortion at high volumes. According to the official Motorola press release, the speakers deliver a frequency response that extends from 20 Hz to 20 kHz, covering the full range of human hearing.

In addition to the speakers, the phone includes a pair of high‑end microphones that support active noise cancellation for voice calls. The microphones are positioned to capture clear speech even in noisy environments, a feature that benefits both everyday conversations and professional video calls.

Bang & Olufsen’s involvement goes beyond hardware. The company has provided a proprietary audio processing algorithm that optimises sound based on the content being played. Whether the user is streaming a podcast, listening to a classical symphony or watching a movie, the algorithm adjusts the equalisation and dynamic range to suit the genre.

For users who prefer wired headphones, the Signature 27 retains a 3.5 mm jack, a rarity among flagship phones. The jack is equipped with a high‑quality digital‑to‑analog converter (DAC) that works in tandem with the Bang & Olufsen tuning to preserve audio fidelity.

Software enhancements for audiophiles

Motorola has bundled a set of audio‑focused software features that complement the hardware. The Audio Boost mode amplifies bass response for genres such as hip hop and electronic music, while Clarity mode enhances vocal presence for podcasts and audiobooks. Users can switch between modes through a simple toggle in the sound settings.

The device also supports high‑resolution audio codecs including FLAC, ALAC and DSD. When paired with compatible streaming services, the phone can play lossless tracks without down‑sampling, ensuring that the full detail of the original recording is retained.Integration with the Bang & Olufsen ecosystem allows seamless playback on the brand’s wireless speakers and headphones. A single tap in the control panel sends the current audio stream to any Bang & Olufsen device on the same Wi‑Fi network.

How the Signature 27 compares with previous models

Motorola’s recent flagship, the Edge 40 Pro, offered a solid camera system and fast charging but lacked a dedicated audio partnership. The Signature 27 builds on the Edge 40 Pro’s Snapdragon 8+ Gen 2 chipset and 12 GB of RAM, while adding the Bang & Olufsen tuned audio chain.

In side‑by‑side tests, the Signature 27 produced clearer mids and tighter bass than the Edge 40 Pro, especially at higher volumes. The difference was most noticeable when playing orchestral pieces, where the Signature 27 maintained instrument separation without sounding harsh.

Battery capacity remains at 5,000 mAh, and the phone supports 65 W wired fast charging. Real‑world tests show that the device can last a full day of mixed usage, including video streaming, gaming and music playback.

Potential impact on the smartphone market

By integrating a high‑end audio system into a mainstream flagship, Motorola may influence other manufacturers to prioritize sound quality. Historically, only a few brands such as Sony and LG have offered dedicated audio tuning in their premium devices. If the Signature 27 receives positive consumer feedback, it could encourage more collaborations between phone makers and audio specialists.

Music streaming services are also paying attention to hardware capabilities. According to a recent CNET audio review, the market for high fidelity mobile listening is growing, driven by users who want to replace portable music players with a single device.

Motorola’s move aligns with the broader trend of smartphones becoming all‑in‑one media hubs. The addition of a reputable audio partner adds a new selling point that differentiates the Signature 27 from other Android flagships that focus primarily on camera performance.

What buyers should consider

Potential owners should evaluate the following factors before purchasing:

• Audio priorities: If high quality sound is a key requirement, the Signature 27 offers tangible benefits over most competitors.
• Camera expectations: The phone includes a 50 MP main sensor, a 12 MP ultra wide lens and a 5 MP macro lens. While solid, it may not match the low‑light performance of some rival devices.
• Software updates: Motorola has pledged three years of Android security updates and two major OS upgrades, which is important for long‑term security.
• Price point: The Signature 27 is positioned in the premium segment, typically priced above $900 in most markets.

Overall, the Signature 27 presents a compelling package for users who value a refined audio experience without sacrificing the core capabilities of a modern smartphone. Its blend of design, performance and sound quality makes it a noteworthy addition to Motorola’s lineup.
