Boult Audio Octave specifications and in-depth review

Boult Audio Octave

Manufacturer: Boult Audio

The Boult Audio Octave are true wireless in-ear earbuds designed for everyday use without the hassle of cables. They carry an IPX5 rating, making them resistant to water splashes, and come with a charging case that extends total playback to 52 hours of combined battery life. A travel bag is included in the box, and voice prompts help with device feedback during use.

On the technical side, the Octave uses a 13 mm driver unit covering a frequency range of 20 Hz to 20,000 Hz, paired with four microphones and a noise-canceling mic setup for calls. Bluetooth 5.3 handles wireless connectivity with a stated range of up to 10 m and an audio latency of 45 ms, while AAC codec support is included. The earbuds charge via USB Type-C and support fast charging, with a full charge taking approximately 1.5 hours.

Pros
  • The charging case extends total playback to 52 hours, making the earbuds practical for extended use without frequent access to a power source
  • Fast charging support reduces downtime when the battery runs low
  • Four microphones combined with a noise-canceling mic setup make these suitable for calls in moderately noisy environments
  • IPX5 water resistance allows use during workouts or in light rain without concern
  • A mute function and voice prompts add useful hands-free convenience during calls
  • A travel bag is included, providing a ready-made storage solution out of the box
Cons
  • No active noise cancellation, so users in loud environments rely solely on the passive isolation of the in-ear fit
  • Wireless charging is not supported, requiring a cable for every recharge
  • Bluetooth range is limited to 10 m, which may be restrictive in larger spaces
  • No ambient sound mode, preventing users from monitoring their surroundings without removing the earbuds
  • Fast pairing and NFC pairing are absent, making the initial connection process more manual
  • No in-ear detection means music does not pause automatically when the earbuds are removed
Who is this for?

The Boult Audio Octave are well matched to everyday listeners who want a fully cable-free, in-ear experience with solid all-day endurance, thanks to the 8-hour earbud battery and 52-hour case capacity. The IPX5 rating makes them a practical choice for workouts and outdoor use where exposure to sweat or light rain is expected. Users who frequently take calls will also find the four-microphone setup with noise-canceling capability useful, and the inclusion of a mute function and voice prompts adds further convenience for those who use their earbuds in a professional or on-the-go context.

Who is this NOT for?

Listeners who prioritize high-fidelity audio with advanced codec support will find the Octave limiting, as LDAC, aptX, and all related variants are absent, leaving AAC as the only elevated codec option. Those who require active noise cancellation for use in loud commuting or office environments will not get that from these earbuds, as only passive isolation through the ear-tip fit is available. Additionally, users who prefer the convenience of wireless charging or need fast Bluetooth pairing will find neither feature supported here.

Final Verdict

The Boult Audio Octave are a straightforward pair of true wireless earbuds that cover the essentials without overreaching. Their strongest asset is endurance — 52 hours of total battery life via the charging case, combined with fast charging support, makes them a reliable daily companion for users who dislike frequent recharging. The IPX5 rating and four-microphone call setup add genuine practical value for active users and those who regularly take calls on the move. Where the Octave fall short is in audio codec depth and the absence of active noise cancellation, which places them firmly in the category of everyday-use earbuds rather than audiophile or commuter-focused options. For users whose priorities are battery endurance, wire-free convenience, and call functionality, the Boult Audio Octave deliver a dependable and well-rounded package.
