Name: Boult Audio Mustang Dash
Brand: Boult Audio
SKU: 73584

Manufacturer: Boult Audio

The Boult Audio Mustang Dash are true wireless earbuds designed for everyday use without the hassle of cables. They sit in-ear and carry an IPX5 sweat-resistant rating, making them a reasonable choice for workouts or commutes. The case extends the total listening time considerably, and the earbuds support multipoint connectivity, allowing simultaneous pairing with two devices at once.

On the technical side, the Mustang Dash use a 13 mm driver with a frequency range of 20 Hz to 20,000 Hz and deliver audio via Bluetooth 5.4 with AAC codec support, keeping latency down to 45 ms. The four-microphone setup includes noise-canceling mics for clearer calls, while fast charging via USB Type-C brings the earbuds back up to power in around 1.5 hours. Battery life sits at 8 hours per earbud charge, with the case adding up to 92 hours of total capacity.

Pros

The charging case holds enough power to extend total listening time to 92 hours, making it practical for extended trips without access to a power outlet
Multipoint connectivity allows simultaneous pairing with two devices, reducing the need to manually switch between sources
Fast charging via USB Type-C gets the earbuds ready in 1.5 hours
Four microphones with noise-canceling capability support clearer call quality in noisy environments
A travel bag is included in the box, offering a ready-made storage solution
IPX5 sweat resistance makes the earbuds suitable for physical activity

Cons

No active noise cancellation means the listener depends entirely on passive isolation from the in-ear fit
Wireless charging is not supported, so the case must always be charged with a cable
Bluetooth range is limited to 10 m, which may be restrictive in larger spaces
No fast pairing or NFC support, requiring manual pairing each time on unsupported devices
There is no find-device feature, making it harder to locate misplaced earbuds
In-ear detection for auto-pausing playback is absent, requiring manual intervention when removing the earbuds

Who is this for?

The Mustang Dash are well-suited to users who want a cable-free listening experience for workouts or daily commutes, thanks to the IPX5 sweat resistance and secure in-ear fit. The 92-hour case capacity and fast charging make them a practical option for frequent travelers or those who dislike carrying charging cables constantly. Users who regularly switch between a phone and a laptop will also benefit from the dual-device multipoint support, and the four-mic noise-canceling setup makes the earbuds a capable option for regular voice and video calls.

Who is this NOT for?

Users who need to block out significant background noise — such as those working in loud offices or commuting on busy transit — will find these earbuds limiting, as there is no active noise cancellation and isolation relies solely on the passive seal of the in-ear fit. Audiophiles or users who prioritize high-fidelity wireless audio transmission will be disappointed by the absence of advanced codecs like LDAC, aptX HD, or aptX Adaptive. Similarly, the 10 m Bluetooth range makes the earbuds a poor fit for users who need reliable connectivity across larger spaces, such as in open-plan environments where the source device may be left at a distance.
