Attention all music lovers and gamers — there’s a new budget contender shaking up the under-₹1200 earbud market.
The Boult Z40 Pro (now sold as GoBoult Z40 Pro) promises 100 hours of battery life, quad-mic ENC, and powerful bass for less than the price of a dinner date.
In this review, I’ll share what it’s really like to use them daily — from binge-watching Netflix to long calls and gaming sessions. If you’re wondering whether this is just another hyped-up TWS or a real performer, you’ll get your answer by the end.
The wireless earbud market has become so crowded that buyers are often left confused between dozens of options under ₹1,500. Some promise loud bass, others push gaming performance — but few manage to offer a truly balanced experience. The Boult Z40 Pro steps in with a mix of premium looks, dependable sound, and battery life that easily beats most of its rivals.
What makes this model stand out is Boult’s attention to real-world convenience. Features like the feather-touch controls, easy Type-C charging, and the comfortable rubber grip case might sound simple, but they actually make a big difference in daily use. This review focuses not only on the numbers but also on how it performs in everyday life — from long work calls to those late-night music sessions before bed.

When you compare these specs with other earbuds under ₹1200, the Z40 Pro clearly looks overpowered. Most models in this segment still come with 10mm drivers or smaller batteries, while Boult packs 13mm drivers and a 100-hour claim — specs usually found in earbuds twice the price.
It’s also encouraging to see a “Made in India” tag here. Boult has moved most of its production locally, which helps reduce dependency on imports and ensures better after-sales support for Indian customers.
Sound Quality: Punchy and Bass-Heavy
Let’s start where it matters most — sound.
The Boult Z40 Pro uses 13mm dynamic drivers, which are noticeably larger than most earbuds in this range. The result? A strong, thumpy bass that’ll please EDM and Bollywood lovers alike.
Vocals come through clearly, and instruments have decent separation. In Arijit Singh’s Phir Aur Kya Chahiye, you can feel the vocals sitting neatly above the bass — rare at this price.
For those who love watching movies or streaming OTT content, the stereo imaging is surprisingly impressive. The dialogues remain clear even in action scenes, and explosions or gunfire in movies like Extraction 2 come with a satisfying punch. This makes the Z40 Pro a good fit not just for music, but also for Netflix and YouTube binge-watchers.
However, if you switch between music genres frequently, you’ll notice that the earbuds lean toward a V-shaped sound signature — meaning boosted bass and treble, while mids (like vocals or instruments) take a slight back seat. It’s not a dealbreaker, but audiophiles who prefer natural tones might want to use an equalizer app to tune it slightly.
If you prefer a more balanced sound, you might find the bass a bit overpowering, but for gym or travel use, it’s fun and energetic.

Design & Comfort: Simple, Premium, and Grippy
Boult nailed the design this time. The rubberized charging case gives it a soft, premium feel and prevents slipping — great if you often toss your earbuds into a backpack or pocket.
The earbuds themselves have a snug in-ear fit. Even after a two-hour listening session or an hour of walking, there’s no ear fatigue.
They come with multiple ear tip sizes, so getting a secure fit is easy. And the lightweight build (around 3.5g per earbud) makes them easy to forget you’re wearing them.
Each color variant of the Z40 Pro has a distinct finish, from matte brown to glossy lavender, which gives users the flexibility to match their personal style. Unlike some shiny earbuds that attract fingerprints, this one maintains a clean look even after long use. It’s a small detail, but one that adds to the premium perception.
Another thing worth noting is how pocket-friendly the case is. Despite the large battery inside, it’s compact enough to fit in jeans or small handbags without creating a bulge. This shows how Boult has carefully optimized the design to keep both functionality and aesthetics in balance.

Battery Life & Charging: King of Endurance
This is where Boult Z40 Pro truly shines. The 100-hour total playtime claim might sound exaggerated, but in real-world use, it’s close.
You get roughly 8–10 hours on a single charge, and the case holds enough for 9–10 full recharges. Even with mixed use — calls, gaming, and music — you can easily go a week without charging.
During testing, I played a mix of Spotify and YouTube videos at around 70% volume and easily got over 9 hours of continuous playback. The case itself took about 2 hours to fully charge, which is quite efficient for such a large battery capacity.
The best part is the consistency — many budget earbuds drain faster after a few months, but the Z40 Pro’s battery holds up even after repeated charging cycles. It’s built for heavy users who don’t want the daily hassle of plugging in.
The Type-C fast charging is another plus. Just 10 minutes of charging gives about 150 minutes of playback — ideal for those who forget to charge overnight.

Connectivity & Controls: Smooth and Responsive
The Bluetooth 5.3 connection is quick and stable. Pairing takes seconds, and reconnection after removing the earbuds from the case happens instantly.
During my test, the range held steady even across two rooms. Controls are touch-based — a single tap to play/pause, double to skip, and long press for gaming mode or voice assistant. The response feels natural and rarely misfires.
However, volume control is missing from the earbuds themselves — something Boult could add in a future model.
Call switching between devices is also quick. You can stay connected to your phone and laptop simultaneously, and switching between them during meetings or calls happens with minimal lag. This multitasking ability adds to the overall convenience, especially for those who work or study online.
Even when gaming in Bluetooth mode, the earbuds don’t show significant lag unless the connected device itself struggles with signal interference. So, for most users, this translates into stable connectivity both indoors and outdoors.

Extra Features: Tailored for Modern Use
- 45ms Low Latency Mode: Perfect for gamers. I tested it in BGMI and Call of Duty Mobile — there was almost zero delay between on-screen actions and sound effects.
- Quad-Mic ENC: While it doesn’t cancel out ambient sounds like ANC does, it cuts background noise effectively during calls. Your voice stays clear even in busy streets.
- IPX5 Rating: Resistant to sweat and light rain — suitable for workouts or outdoor runs.
- Voice Assistant Support: Works with Google Assistant and Siri with a long touch.
Another thoughtful inclusion is the smart touch customization. You can reconfigure the tap patterns using Boult’s companion app (available on Android), which helps users who accidentally trigger unwanted actions. It’s a small but smart touch that improves user control.
Also, the earbuds come with a voice prompt system, alerting you when you switch modes or connect to a device. These small audible cues make the experience smoother, especially for beginners who aren’t used to touch-based earbuds.

Real-World Experience: Everyday Performer
After using it for over a week, here’s the summary:
- Office Calls: The quad mics make conversations clear, though they don’t block heavy wind noise completely.
- Commuting: Fit is secure, bass keeps things fun, and battery anxiety simply disappears.
- Gaming: Low latency mode genuinely enhances responsiveness — something many budget TWS fail at.
For ₹1,099, it’s hard to find another pair that balances performance, design, and battery life so well.
The earbuds also perform reliably during long commute hours — no overheating, no sudden disconnections, and a comfortable fit even during sweaty metro rides. For gym users, the IPX5 protection ensures that a bit of sweat or drizzle won’t damage the internals.
Voice calls deserve another mention. While Boult markets the quad-mic ENC heavily, it genuinely helps in practical use. Even during outdoor video calls, voices remain crisp, and the other person hears less ambient noise compared to typical dual-mic earbuds.
Pros and Cons
Despite the small drawbacks, the Z40 Pro’s overall performance exceeds expectations for its price. For most users, these minor cons will barely affect daily use, especially given the excellent combination of audio power, comfort, and durability.

Boult Z40 Pro vs Competitors
When compared with other earbuds like Boat Airdopes 170 or Noise Buds VS102, the Boult Z40 Pro easily outpaces them in total battery backup and microphone quality. While Boat offers a more balanced sound, it doesn’t match the low-latency performance or bass output that Boult provides for gaming and music.
In terms of design, Boult’s rubberized case gives it an edge over the glossy plastic seen in most alternatives. Even after several days of use, the matte surface hides scratches better. So, for those who value both looks and practicality, the Z40 Pro feels more premium without increasing the cost.
