Meizu OpenBlus 2 specifications and in-depth review

Meizu OpenBlus 2

Manufacturer: Meizu

The Meizu OpenBlus 2 are true wireless earbuds designed with an open-ear fit, making them a practical option for users who want to stay aware of their surroundings without giving up audio playback. They come with wingtips for a more secure hold during everyday use, and the included travel bag adds a layer of convenience for users on the go. Notably, active noise cancellation is present despite the open-ear form factor, which is a less common combination in this category.

On the technical side, the earbuds use a 16.2 mm driver unit and cover a frequency range of 20 Hz to 20,000 Hz with an impedance of 16 Ohms. Bluetooth 5.3 handles wireless connectivity with a maximum range of 10 meters and an audio latency of 50 ms. Battery life reaches 9 hours per charge, with the charging case extending total playback to 27 hours; fast charging is supported, and a full charge takes around 1.5 hours via USB Type-C. Additional features include a noise-canceling microphone, ambient sound mode, mute function, voice prompts, and a battery level indicator.

Pros
  • Active noise cancellation is included despite the open-ear form factor, which is uncommon for this style of earbud
  • The charging case extends total battery life to 27 hours, providing meaningful usage time between full recharges
  • Fast charging support reduces downtime when the battery runs low
  • Wingtips are included to help secure the fit during movement
  • A noise-canceling microphone helps maintain call clarity in noisier environments
  • A travel bag is included, making transport and storage more practical
Cons
  • The maximum Bluetooth range of 10 meters is limited for users who move around while listening
  • No advanced audio codecs are supported — LDAC, aptX variants, and AAC are all absent, restricting high-quality wireless audio transmission
  • Wireless charging is not supported, requiring a cable for every recharge
  • There is no in-ear detection, so music does not pause automatically when the earbuds are removed
  • The find-device feature is absent, which can be inconvenient if an earbud is misplaced
Who is this for?

The Meizu OpenBlus 2 are well suited to users who need to remain aware of their surroundings while listening — such as those who commute, exercise outdoors, or work in shared spaces. The open-ear design combined with ambient sound mode makes it practical for situations where complete audio isolation would be unsafe or inconvenient. Users who frequently take calls will also benefit from the noise-canceling microphone and headset capability, while the included wingtips and travel bag make it a reasonable choice for those with an active, on-the-go lifestyle. The 27-hour combined battery life and fast charging support further suit users who need reliable, extended daily use without frequent downtime.

Who is this NOT for?

Users seeking an immersive, isolated listening experience will find this product lacking, as the open-ear fit provides no passive noise isolation, meaning external sounds are always present. Audiophiles or those who prioritize high-resolution wireless audio will be disappointed by the absence of advanced codecs such as LDAC, aptX, or AAC, which limits the quality ceiling for wireless playback. Additionally, users who frequently move between devices or expect seamless automatic pairing workflows may find the lack of fast pairing and NFC pairing cumbersome, and those who want to locate misplaced earbuds will be hindered by the missing find-device feature.

Final Verdict

The Meizu OpenBlus 2 carves out a clear niche as a true wireless earbud built around the open-ear form factor, making it most relevant for users who prioritize situational awareness over audio isolation. Its most notable technical distinction is the inclusion of active noise cancellation within an open-ear design — a combination that remains uncommon in this category — paired with a noise-canceling microphone and a respectable total battery life of 27 hours. The absence of advanced audio codecs and passive noise isolation does narrow its appeal for more demanding listeners, but for everyday use, commuting, and hands-free communication, the Meizu OpenBlus 2 presents a practical and reasonably well-equipped option within its category.
