boAt Nirvana Crystl

boAt Nirvana Crystl Overview 

Design and Audio 

One of the major highlights of the Nirvana Crystl is its transparent design. The buds are available in Black, Red, and Yellow color options with a clear plastic case. On the bottom side, you can also find some of the electronics seeping through, which adds an extra hint of that cool factor for sure. Even the buds themselves have a see-through look and resemble the boAt Nirvana Ion in terms of weight and dimensions. There’s an IPX4 rating for the buds, but the case isn’t officially certified. 

In terms of audio, the boAt Nirvana Crystl ships with dual 10mm drivers with a "Signature Sound" preset. But you can customize it with a 7-band equalizer via the boAt Hearables app. There are tons of audio features like Spatial Audio and Low Latency Mode.

Noise Cancellation and Connectivity Features

Just like the Nirvana Ion, Nirvana Crystl has up to 32dB of Active Noise Cancellation with quad mic ENx for clear calls. There’s also in-ear detection and multipoint connectivity. You can customize the features and touch controls via the boAt Hearables app. 

In terms of battery life, the Nirvana Crystl lasts up to 100 hours on a single full charge and provides up to 220 minutes of playback with a quick 10-minute plug-in. The case houses a large 480mAh cell, while the buds house a 70mAh battery each. For a full refill, it takes the buds roughly an hour and a half while the case needs 2.5 hours via the Type-C port at the bottom.
