Boult Audio W45

Name: Boult Audio W45
Brand: Boult Audio
SKU: 5190

Manufacturer: Boult Audio

The Boult Audio W45 are true wireless in-ear earbuds designed for everyday use without the hassle of cables. They carry an IPX5 water resistance rating, making them reasonably resilient against sweat and light splashes. The earbuds come with a travel bag included and support voice prompts, a mute function, and can be used as a headset for calls.

On the connectivity side, the W45 runs on Bluetooth 5.4 with a maximum range of 10 m and a low audio latency of 50 ms, alongside fast pairing and USB Type-C charging support. Each earbud houses a 13 mm driver unit covering a 20 Hz to 20,000 Hz frequency range, and passive noise isolation helps reduce ambient sound. A quad-microphone setup with noise-canceling capability handles call quality, while the charging case extends total playtime to 40 hours, with the earbuds themselves offering 8 hours per charge and a 1.5-hour charge time with fast charging support.

Pros

The charging case extends total playback to 40 hours, making it practical for extended use without frequent recharging
Fast charging support reduces downtime when the battery runs low
A four-microphone array with noise-canceling capability is well-suited for calls in noisy environments
Bluetooth 5.4 with fast pairing allows for quick and reliable wireless connections
IPX5 water resistance provides adequate protection against sweat and splashes during physical activity
A travel bag is included, adding convenience for users who carry the earbuds on the go

Cons

Active noise cancellation is absent, so users in loud environments rely solely on passive noise isolation
No wireless charging support, requiring a wired connection via USB Type-C each time
The 10 m Bluetooth range is relatively limited for situations where the source device is at a distance
Spatial audio, Dolby Atmos, and advanced audio codecs such as LDAC and aptX are not supported, limiting high-fidelity audio options
There is no in-ear detection, so music does not pause automatically when the earbuds are removed

Who is this for?

The Boult Audio W45 are well-suited for users who need a reliable pair of true wireless earbuds for daily commutes, workouts, or casual listening, thanks to the IPX5 water resistance and a total battery life of 40 hours with the charging case. The four-microphone noise-canceling setup makes them a practical choice for people who frequently take calls on the go, while fast pairing and fast charging support cater to those who value convenience and minimal setup time. The included travel bag and compact true wireless form factor also make them a reasonable fit for users who carry their earbuds regularly.

Who is this NOT for?

Users seeking an immersive or high-fidelity audio experience may find the W45 limiting, as the earbuds lack active noise cancellation, spatial audio, and advanced codecs such as LDAC or any aptX variant. Those who work or exercise in environments where they need to remain aware of their surroundings will miss an ambient sound mode, which is absent here. Additionally, users who require a wider Bluetooth range — such as when moving between rooms while leaving a device behind — may find the 10 m maximum range restrictive, and those accustomed to wireless charging will need to adapt to wired-only charging via USB Type-C.
