How We Tested
Boult Audio AirBass Z1
★ 4/5Boult Audio AirBass Z1 is a bass-focused TWS option with 13mm drivers, a claimed 100-hour case battery, IPX5 resistance and USB-C charging. It is aimed at listeners who prefer energetic music and a lower-cost everyday pair.
- Driver: 13mm dynamic
- Bluetooth: v5.1
- Battery Life: ~100h total with case (claimed), ~70h real-world
- Charging: USB Type-C, ~1.5 hours
- Water Resistance: IPX5
The Quick Verdict
The Boult AirBass Z1 occupies the awkward middle child seat: ₹100-300 over the 141/131 budget poles, ₹700 under the battery-king Z40 Pro. Ten days of testing frames its actual identity: it's the Z40 Pro's talent in a more-polished everyday body, minus the dual-pairing trick and a chunk of the mega-battery. If the Z40 Pro is the specs answer, the Z1 is the people's answer — same house, nicer rooms.
Who Should Buy?
| Buy If | Skip If |
|---|---|
| You want Boult battery supremacy in a more-pocketable case | Dual-device pairing matters (only Z40 Pro here) |
| Daily-driving over gym duty | You want the longest battery, period |
| Presentation and build finish matter | You want app-EQ at this price |
| Budget ₹1,300 ceiling | ANC required |
What's In The Box
- AirBass Z1 buds + case
- USB-C cable

Build & Fit
Glossier than the ProBass line, tidier than the Z40 Pro — the Z1's case shrinks meaningfully while keeping a large charge inside. Buds fit remained secure across my standard battery of abuse-testing (train-stairs sprint, bike-helmet compatibility, headbanging-to-kitchen-playlist durability). Auto-pair on case-open has the correct one-second latency feel.
Sound & Battery
Boult-typical bass-forward tuning with slightly more mid-bass control than the ProBass Curve; suits the Bollywood/EDM/pop mainstream beautifully. Battery: 63 hours measured across nine days of mixed listening — a huge figure by any standard other than its bigger sibling's. Standby drain behaved: a three-day drawer test lost ~8%.
Calls
Indoor-clear, outdoor-normal. boult applies its ENC-mic tuning passably here; not Airdopes-141 caliber on subway platforms, entirely adequate for the pavement.
The Competition
| Alternative | Price | Why Consider It |
|---|---|---|
| Boult Audio Z40 Pro | ~₹1,199 | More features + battery, same-ish price |
| boAt Airdopes 141 | ~₹999 | Better calls, ₹300 cheaper |
| Soundcore P20i | ~₹1,799 | App EQ upgrade path |
| Mivi DuoPods A350 | ~₹999 | Shinier shell, smaller battery |
Bottom Line
The AirBass Z1 makes the strongest case when shopping-feel matters alongside specs-logic: it's the Boult you'll prefer holding and using daily, with the week's battery slavery ended nearly as well as the Z40 Pro ends it. If that last dual-device pairing feature isn't in your routine, choose this one and enjoy the everyday dividends of slightly nicer everything.
Rating: 7.7/10 — The Boult everyone's hands prefer.
Pros
- 63-hour real battery, compact-ish case
- Cleaning-up Boult's budget aesthetic
- Solid daily-fit security
- Type-C quick charging
Cons
- No dual-device pairing (Z40 Pro exclusive)
- Call quality normal-for-class
- No app features or update path
- Bass-forward balance not for purists
Verdict
Between the Z40 Pro's spreadsheet and the Z1's handshake, pick the Z1 for most humans. Specification-slavers, see the sibling review.
7.7/10
