Boult Audio Xena Pro specifications and in-depth review

Boult Audio Xena Pro

Manufacturer: Boult Audio

The Boult Audio Xena Pro are true wireless in-ear earbuds designed for everyday wireless listening without the clutter of cables. They carry an IPX5 water resistance rating, making them reasonably suited for workouts and light outdoor use. A total battery life of up to 100 hours — combining the earbuds and their charging case — positions them as a practical option for users who need extended usage between full recharges.

On the technical side, the Xena Pro feature a 13 mm driver unit and cover a frequency range of 20 Hz to 20,000 Hz. Connectivity runs on Bluetooth 5.4 with AAC codec support and an audio latency of 45 ms, alongside a maximum wireless range of 10 meters. Four microphones with noise-canceling capability handle call and voice input, while fast charging support, USB Type-C, passive noise isolation, and a mute function round out the feature set.

Pros
  • The charging case extends total battery capacity to 100 hours, reducing how often the case itself needs to be recharged
  • Fast charging support means less time waiting before the earbuds are ready to use
  • Four microphones with noise-canceling capability make for more reliable call quality in noisy environments
  • Bluetooth 5.4 provides a relatively current wireless standard for stable connectivity
  • A travel bag is included in the box, adding practical value for users who carry earbuds on the go
  • IPX5 water resistance makes the earbuds usable during workouts or in light rain without concern
Cons
  • Active noise cancellation is absent, so users in loud environments rely solely on the passive isolation provided by the in-ear fit
  • Wireless charging is not supported, requiring a cable connection every time the case needs to be recharged
  • No fast pairing support means the initial Bluetooth connection process may take a few extra steps
  • The 10-meter maximum Bluetooth range is limited, restricting movement away from the source device
  • No ambient sound mode means there is no way to let in environmental audio without removing the earbuds
  • Advanced audio codecs such as LDAC, aptX, and Bluetooth LE Audio are not supported, limiting high-resolution audio options
Who is this for?

The Boult Audio Xena Pro are a practical fit for users who prioritize long all-day battery life, particularly those who need reliable wireless listening throughout the day without frequent recharging stops. The IPX5 water resistance and secure in-ear fit make them a reasonable choice for gym sessions, commutes, or light outdoor activity. Users who frequently take calls will also benefit from the four-microphone setup with noise-canceling capability, along with the mute function and headset support built into the earbuds.

Who is this NOT for?

Users who require active noise cancellation for focused listening in consistently loud environments — such as open offices, aircraft, or busy commutes — will find these earbuds fall short, as only passive isolation is available. Audiophiles or those seeking high-resolution wireless audio will be limited by the absence of advanced codecs like LDAC or aptX, with AAC being the highest supported option. Additionally, users who value smart convenience features such as ambient sound mode, in/on-ear detection, or wireless charging of the case will find those capabilities missing here.

Final Verdict

The Boult Audio Xena Pro are a straightforward set of true wireless earbuds that cover the essentials competently — IPX5 water resistance, a four-microphone noise-canceling setup for calls, and a combined battery capacity of 100 hours that stands out as the product's most practical strength. Running on Bluetooth 5.4 with AAC support and fast charging, they are well-suited for everyday listeners who want reliable wireless audio without the complexity of advanced features. That said, the absence of active noise cancellation, high-resolution codec support, and smart convenience features means the Xena Pro are best matched to users with straightforward needs rather than those chasing a feature-rich or audiophile-grade experience.
