boAt Airdopes 138 Gen 2 TWS Earbuds with 70H Playback

Seventy hours of combined playback is the kind of number that makes a power bank feel unnecessary for earbuds. The boAt Airdopes 138 Gen 2 carries that capacity without being bulky about it — the case charges the earbuds multiple times over before it itself needs attention, which for most people means charging once every week or two rather than every night. And when the case does run low, ASAP™ Fast Charging is genuinely impressive here: 10 minutes returns 300 minutes of playback, which is five hours back from a charge shorter than a coffee break.

Sound Quality

The 13mm dynamic drivers produce a sound that’s full and engaging — bass hits with presence, vocals stay clear and forward in the mix, and the high end has enough detail without becoming fatiguing over extended sessions. It’s a tuning that works across genres rather than favouring one over another. Podcasts come through with voice clarity, bass-heavy music has the weight it should, and films feel immersive enough to hold attention. Nothing here feels artificially boosted to impress on first listen and disappoint on the third.

Calls and Low Latency

ENx™ Environmental Noise Cancellation across dual mics keeps your voice separated from background noise during calls — useful in open offices, busy streets, or anywhere the ambient level competes with conversation. The filtering happens automatically, so whoever you’re speaking to hears you rather than your surroundings. For gaming and video content, BEAST™ Mode at 45ms latency keeps audio synced tightly enough that the delay stops being a distraction — you simply play, and the sound follows.

Connectivity and Build

Bluetooth 5.4 connects quickly via IWP™ Instant Pairing — open the case, earbuds are live and connected before you’ve fully extended your arm. Stable up to 10 metres, efficient on battery. IPX4 splash resistance covers sweat and light rain for workouts and commutes. Touch controls handle playback, calls, track switching, and voice assistant access without needing your phone, and Google Assistant and Siri are both supported for hands-free queries.
