Design & Comfort

Both the Boult Audio Z40 Ultra and Boat Nirvana Ion ANC adopt a classic in-ear stem design. Comfort is subjective—one design might feel amazing for some and less ideal for others.

Both are rated IPX4 or IPX5 for water and sweat resistance, making them gym-friendly.

Active Noise Cancellation (ANC) This is where the two earbuds diverge. The Boult Audio Z40 Ultra features true Active Noise Cancellation (ANC), promising to actively counter external noise with up to 32dB of reduction.

The Boat Nirvana Ion ANC relies on Environmental Noise Cancellation (ENC), which is generally less effective at blocking out consistent background noise like engine rumbles or traffic. ANC performance on affordable earbuds won’t rival top-tier models, but the Z40 Ultra should have a noticeable edge here.

Audio Quality

The Boult Audio Z40 Ultra delivers a powerful, bass-forward sound signature. If you crave a thumping low end, these will please.

Audiophiles seeking a perfectly balanced presentation might prefer the Boat Nirvana Ion ANC’s more neutral approach. Of course, sound preference is subjective – the best way to gauge this is to try them yourself if possible.

Battery Performance

The Boult Audio Z40 Ultra boasts an exceptional battery life of up to 100 hours (with the charging case), whereas the Boat Nirvana Ion ANC offers upto 120 hours of total playback.


Both earbuds do a decent job with call quality in quieter environments. The Boat Nirvana Ion ANC likely has a slight edge when it comes to background noise filtering during calls thanks to its ENC tech. However, don’t expect miracles at this price point – windy areas will still prove challenging.


Neither model boasts an ultra-low latency mode specifically tailored for gaming. You might notice a slight delay between on-screen action and audio. or serious, competitive gaming, more expensive options with dedicated gaming modes would be better.

Other Features

The Boult Audio Z40 Ultra also includes some neat features like customizable EQ (via an app) and fast charging. The Boat Nirvana Ion ANC also supports fast charging and also offer additional customization options through app.
