Black Shark OWS 700 specifications and in-depth review

Black Shark OWS 700

Manufacturer: Black Shark

The Black Shark OWS 700 are open-ear true wireless earbuds designed for users who want to stay aware of their surroundings while listening. Weighing just 18 g, they use an open-ear fit secured by wingtips and carry an IPX4 rating for sweat resistance, making them a practical option for workouts and outdoor activity. Stereo speakers are present on both sides, and a travel bag is included in the box for easy transport.

Audio is driven by 16.2 mm drivers covering a frequency range of 20 Hz to 20,000 Hz, with neither active noise cancellation nor passive noise isolation — a deliberate trade-off of the open-ear design. The earbuds connect via Bluetooth 5.3 with a maximum range of 10 m and an audio latency of 60 ms; no advanced codecs such as LDAC, AAC, or aptX are supported. The built-in rechargeable battery provides 6 hours of playback, with the charging case extending total use to 18 hours. A full charge takes 1.5 hours via USB Type-C, and fast charging is supported. A noise-canceling microphone is included for calls, along with a mute function, voice prompts, and an on-device control panel.

Pros
  • True wireless design with no connecting cable between the earbuds, keeping the setup completely wire-free
  • At 18 g, the earbuds are notably lightweight, reducing fatigue during extended wear
  • Wingtips and an open-ear fit provide a secure hold without creating an in-ear seal, allowing environmental sounds to pass through naturally
  • A travel bag is included in the box, offering a ready-to-use storage solution
  • Fast charging is supported, helping reduce downtime between uses
  • The charging case extends total playback to 24 hours, compensating for the modest 6-hour earbud battery on its own
Cons
  • No active noise cancellation and no passive noise isolation, meaning there is no way to block out ambient sound
  • No advanced audio codecs are supported — LDAC, AAC, and the full aptX family are all absent, limiting wireless audio quality options
  • Bluetooth range is limited to 10 m, which restricts movement away from the source device
  • No fast pairing or NFC pairing, making the initial connection process less convenient
  • No in/on-ear detection, so playback does not pause automatically when the earbuds are removed
  • No find-device feature, making it difficult to locate the earbuds if misplaced
Who is this for?

The Black Shark OWS 700 suits users who prioritize situational awareness during outdoor activities, as the open-ear design lets ambient sound pass through freely without any noise isolation. The lightweight 18 g build combined with wingtips makes them a practical fit for running or casual workouts, and the IPX4 sweat resistance adds durability in those conditions. Users who prefer a fully wire-free setup with a compact carrying solution will also find the true wireless design and included travel bag well suited to daily on-the-go use.

Who is this NOT for?

These earbuds are not well matched to users who need noise isolation or active noise cancellation, as neither is available — making them a poor fit for commuting, open offices, or any environment where blocking out background sound matters. Those who rely on high-fidelity wireless audio through codecs like LDAC, AAC, or aptX will find no support here, limiting audio transmission quality. The 6-hour earbud battery and 10 m Bluetooth range also make them less suited to users with extended, stationary listening sessions who need to move freely around a larger space.

Final Verdict

The Black Shark OWS 700 is a straightforward open-ear true wireless earbud built around comfort, awareness, and convenience rather than audio isolation or codec versatility. Its lightweight 18 g form, true wireless design, and IPX4 sweat resistance make it a dependable companion for outdoor activity and casual daily use, and the charging case's 18-hour reserve meaningfully extends its modest 6-hour per-charge playback. Codec support and noise management are minimal by design, so users with specific audio quality or isolation requirements will need to look elsewhere — but for those who simply want an unobtrusive, wire-free open-ear option that stays secure and travels easily, the Black Shark OWS 700 delivers a focused and practical experience.
