boAt Nirvana Crystl TWS Earbuds for Sound Quality and ANC — immersive listening built to last

Nirvana Crystl gives you a bass-forward sound with decent clarity for daily listening. Vocals and treble don't come through with the same weight as the bass. For casual music and films, it sounds full rather than thin.

ANC cuts steady sounds like bus engines, metro noise, and office hum quite well. It also helps during crowded commutes, especially when the background noise stays constant. Loud conversations nearby still come through.

Battery is easily the biggest strength here. The case and earbuds together are rated for up to 100 hours, so long trips don't need regular charging stops. That figure gives this pair a serious advantage for travel.

A full recharge takes around 2.5 hours through USB Type-C. Fast charging also gives you useful playback after a shorter top-up. You won't need to leave it plugged in overnight every time.

The in-ear fit feels secure when the tips sit properly. Some people find the buds heavy after wearing them for several hours, mainly because of the large battery. Short listening sessions feel much easier than full-day use.

The earbuds are bulkier than many everyday TWS pairs. That extra weight can become noticeable during long calls or continuous video watching. They stay put well, but comfort drops once the session gets very long.

The case has a solid everyday feel and the lid shuts with a soft click. It doesn't feel flimsy when opened or closed repeatedly. The case is still bulky enough to notice in tighter pockets.

IPX4 protection is enough for sweat and light splashes during normal use. It suits walks, gym sessions, and sudden light rain better than completely unprotected earbuds. Don't treat it like a pair made for heavy water exposure.

OnePlus Nord Buds feel less bulky, and their ANC is slightly better in direct daily use. Nirvana Crystl wins clearly on its 100-hour battery and stronger bass output. Pick OnePlus for lighter comfort, or this one for long battery life.

Nirvana Crystl is the stronger pick if battery backup is your main priority. Its 100-hour total playback leaves most regular TWS options far behind. Realme Buds make more sense if you already prefer that brand's connection behaviour.

Nirvana Crystl uses ENx microphones to keep voices clear in mild background noise. Calls sound good in quieter places, but crowded areas are where its limits show. OPPO Enco Air3 is worth considering if call quality matters more than huge battery backup.

Pairing is quick, and the 10-metre range works fine in normal rooms. Some connections can drop during calls and send the sound back to the phone speaker. That interruption is the main weak point in its connectivity.

The ENx mic setup handles mild outdoor noise fairly well. Voice quality is good in normal streets, offices, and quieter public places. Heavy traffic or crowded stations can still make conversations difficult.

Multipoint is included, so the earbuds can stay connected with more than one device. Switching is useful when moving between a phone and laptop. Calls remain the important test because connection drops have been reported during them.

The 60ms mode keeps audio delay low enough for casual mobile games. It works better for racing and casual action games than games needing exact competitive timing. Music and video playback don't need the mode switched on.

They suit long trips mainly because the battery lasts for days and ANC reduces engine noise. The secure fit also helps when you're moving around with a bag or luggage. Their heavier shape is the only thing you notice after many hours.

Touch controls can feel sensitive when you adjust the earbuds in your ears. Accidental taps may switch between ANC and ambient modes without an intentional press. Keeping the earbuds in place properly reduces most of those unwanted changes.

A few pairs have stopped working within three to twelve months, which raises a real durability concern. Repeated drops can also damage the earbuds or their outer shell. The one-year warranty gives you a service route, but the early failures are still frustrating.
