boAt Airdopes 121 V2 Plus

Manufacturer: boAt

The boAt Airdopes 121 V2 Plus are true wireless in-ear earbuds designed for everyday use without the hassle of cables or neckbands. They carry an IPX4 rating, making them resistant to sweat during workouts or commutes, and connect over Bluetooth 5 for a stable wireless link. A USB Type-C port handles charging, and fast charging support means less time waiting before you can get back to listening.

Each earbud houses an 8 mm driver unit covering a frequency range of 20 Hz to 20,000 Hz, with passive noise reduction helping to block out ambient sound. On the microphone side, the earbuds feature four microphones with noise-canceling capability, making them suitable for calls and voice use. The internal battery holds 40 mAh and delivers around 3.5 hours of playback, while the 380 mAh charging case extends total listening time to roughly 10.5 hours. Additional touches include a battery level indicator, voice prompts, a mute function, touch controls on the device, and a travel bag included in the box, all backed by a one-year warranty.

Pros
  • Four microphones with noise cancellation support cleaner call quality by reducing background interference
  • IPX4 sweat resistance makes the earbuds suitable for use during physical activity
  • The charging case provides a total of 10.5 hours of combined playback, extending usability throughout the day
  • Fast charging support reduces downtime when the battery runs low
  • USB Type-C port offers a widely compatible and reversible charging connection
  • A travel bag is included in the box, adding practical storage and portability out of the package
Cons
  • A single charge lasts only 3.5 hours, which may require frequent top-ups for longer listening sessions
  • No active noise cancellation means the user depends entirely on passive isolation to block ambient sound
  • Bluetooth range is limited to 10 m, restricting movement away from the paired device
  • No advanced audio codec support — AAC, LDAC, aptX, and all aptX variants are absent
  • In/on-ear detection and automatic music pause are not available, requiring manual playback control when removing the earbuds
Who is this for?

These earbuds are a practical choice for users who prioritize hands-free calling and voice use, given the four-microphone setup with noise-canceling capability. The IPX4 sweat resistance makes them well suited for gym sessions, outdoor runs, and other physical activities where moisture exposure is expected. Users who frequently move between tasks throughout the day will also benefit from the combined 10.5-hour battery system and fast charging support, which help keep downtime to a minimum without requiring long waits at a charger.

Who is this NOT for?

Users who value long uninterrupted listening sessions on a single charge may find the 3.5-hour earbud battery limiting, especially in situations where access to the charging case is not convenient. The absence of any advanced audio codec — including AAC, LDAC, and all aptX variants — means these earbuds are not suited for those who prioritize high-fidelity audio reproduction. Similarly, users in consistently noisy environments will find the lack of active noise cancellation a real shortcoming, as passive isolation alone may not provide adequate sound blocking in loud public spaces or during commutes.

Final Verdict

The boAt Airdopes 121 V2 Plus are a straightforward set of true wireless in-ear earbuds built around everyday practicality. Their standout qualities lie in the four-microphone noise-canceling setup and the IPX4 sweat resistance, which together make them a reliable option for active users and those who take frequent calls on the go. The combined 10.5-hour battery system and fast charging support add a layer of daily usability, even if the per-charge listening time on the earbuds themselves is modest. Users expecting advanced audio codecs, active noise cancellation, or extended single-charge endurance will find the specifications fall short of those demands. For straightforward wireless listening, fitness use, and voice communication, the Airdopes 121 V2 Plus delivers a focused, no-frills experience that aligns well with its intended audience.
