HMD Dub X50 specifications and in-depth review

HMD Dub X50

Manufacturer: HMD

The HMD Dub X50 are true wireless in-ear earbuds designed for everyday use without the hassle of cables. They feature a compact form factor with no neckband or wingtips, and come with a carrying case included in the box. With a total playback time of up to 70 hours combined across the earbuds and charging case, they are built to handle extended listening sessions without frequent recharging.

On the technical side, the HMD Dub X50 connects via Bluetooth 5.3 with fast pairing support and a maximum wireless range of 10 meters. Charging is handled through USB Type-C with fast charging support, and the earbuds reach a full charge in around 2 hours. A quad-microphone setup with noise-canceling mic technology handles calls and voice input, while in-ear detection automatically pauses audio when the earbuds are removed. The IPX4 rating provides protection against sweat, and passive noise isolation helps reduce ambient sound during use.

Pros
  • The charging case extends total playback to over 52 hours, making the earbuds well-suited for extended use between top-ups
  • Fast charging support reduces downtime when the battery runs low
  • In-ear detection automatically pauses playback when an earbud is removed, which helps conserve battery and avoids missed audio
  • A quad-microphone setup with noise-canceling mic technology supports clearer voice pickup during calls
  • Bluetooth 5.3 with fast pairing enables quick and stable wireless connections
  • A travel bag is included, offering a practical way to carry and protect the earbuds on the go
Cons
  • No active noise cancellation, so sound isolation relies entirely on the passive seal of the in-ear fit
  • Wireless charging is not supported, requiring a cable for every recharge
  • No ambient sound mode, meaning external sounds cannot be intentionally let in without removing the earbuds
  • Bluetooth range is limited to 10 meters, which may restrict movement from the paired device
  • No support for advanced audio codecs such as LDAC, aptX, or AAC, limiting audio transmission quality options
Who is this for?

These earbuds are a solid fit for users who prioritize long listening sessions, as the combined battery life of over 52 hours means less frequent charging throughout the week. The IPX4 sweat resistance and in-ear fit make them a practical choice for fitness and active daily use, where a secure seal and moisture protection matter. Those who frequently take calls on the go will also benefit from the quad-microphone setup with noise-canceling mic support, along with in-ear detection that pauses audio automatically when an earbud is removed.

Who is this NOT for?

Users who work or commute in noisy environments will likely find these earbuds limiting, as there is no active noise cancellation to block out disruptive ambient sound. Audiophiles or those who demand high-fidelity wireless audio transmission will be constrained by the absence of advanced codecs such as LDAC or aptX, which limits the quality ceiling of the Bluetooth audio signal. Additionally, users who need to stay aware of their surroundings without removing their earbuds — such as cyclists or pedestrians in busy areas — will find the lack of an ambient sound mode a notable drawback.

Final Verdict

The HMD Dub X50 is a straightforward pair of true wireless in-ear earbuds that delivers where it counts for everyday listeners and active users. Its combined battery life exceeding 52 hours, fast charging support, and sweat-resistant build make it a dependable option for those who spend long hours away from a charger. The quad-microphone system with noise-canceling capability adds genuine call utility, and practical touches like in-ear detection and a bundled travel bag round out the package sensibly. That said, the absence of active noise cancellation and high-quality codec support means it is best suited for casual listeners rather than those chasing premium audio performance. Overall, the Dub X50 positions itself as a functionally capable everyday earbud with a focus on endurance and usability over audiophile-grade refinement.
