Boult Audio Z40 True Wireless in Ear Earbuds Review: A Budget-Friendly Powerhouse with Punchy Sound
In a world where wireless earbuds are flooding the market, it’s getting harder to find a pair that truly stands out—especially without breaking the bank. But Boult Audio Z40 True Wireless in Ear Earbuds are proving that affordability doesn’t have to come at the cost of quality. Whether you’re commuting, working out, gaming, or just relaxing with your favorite playlist, the Z40s offer a reliable and surprisingly premium experience for their price tag.
Let’s dive deep into what makes the Boult Audio Z40 a compelling choice in the budget earbuds category—and where it could improve.
Design & Comfort: Light, Sleek, and Daily-Use Ready
At first glance, the Boult Audio Z40 True Wireless in Ear Earbuds look stylish and compact. The matte finish on the case and buds gives them a clean, minimal look that doesn’t scream for attention—but still feels premium. The earbuds are lightweight and snug, offering a secure fit that holds up during jogs and gym sessions. They’re also rated IPX5 water-resistant, which is a big plus for fitness enthusiasts or those caught in the occasional rain.
Comfort-wise, the ear tips are soft and come in different sizes, making them comfortable even during long listening sessions. No ear fatigue, no awkward adjusting—just plug in and go.
Sound Quality: BoomX™ Delivers the Bass
Now, let’s talk audio. Boult has equipped the Z40s with BoomX™ bass technology, and for the price, the sound output is genuinely impressive. The bass is punchy without being overwhelming, and mids and highs are handled cleanly. Whether you’re into EDM, podcasts, or Bollywood playback, the audio remains balanced and lively.
The clarity in vocals and instruments makes them ideal for a variety of genres, and the stereo separation adds a nice immersive layer for casual movie watching or gaming.
Low-Latency Mode: Built for Gamers Too
One feature that really stands out on the Boult Audio Z40 True Wireless in Ear Earbuds is its low-latency gaming mode. With a latency as low as 45ms, you get near real-time audio during gameplay—a rare find in this price range. If you’re someone who enjoys mobile gaming and wants a competitive edge, this feature adds real value.
Switching to gaming mode is easy and responsive, with minimal lag between in-game action and what you hear. It won’t replace high-end wired setups, but for casual gaming, it’s more than enough.
Battery Life: A Major Win
Battery life is where the Boult Audio Z40 really flexes its muscles. With up to 60 hours of total playtime (including the case), you can go days without needing to recharge. The earbuds alone can last around 8–10 hours on a single charge, which is impressive even compared to some premium brands.
Fast charging is another sweet bonus. Just 10 minutes of charge gives you around 100 minutes of playback, making it super handy for those “I forgot to charge them” moments.
Connectivity & Controls: Smooth and Reliable
The earbuds use Bluetooth 5.3, which means faster pairing, lower power consumption, and a stronger signal. In real-world use, connectivity is rock-solid. They pair instantly with your phone, and once connected, they remember your device—so next time, it’s plug-and-play.
Touch controls are responsive and easy to learn. You can play/pause music, skip tracks, answer calls, and even switch to low latency mode with simple gestures. No laggy taps or confusing functions.
Call Quality: Decent for Everyday Use
The Boult Audio Z40 True Wireless in Ear Earbuds come with environmental noise cancellation (ENC), which filters out background noise during calls. While it won’t give you crystal-clear corporate-call-level clarity, it’s more than sufficient for voice calls and casual video chats. People on the other end could hear me clearly even in mildly noisy surroundings.
Final Verdict: Worth Every Rupee
If you’re in the market for budget-friendly earbuds that actually deliver more than they promise, the Boult Audio Z40 True Wireless in Ear Earbuds should be high on your list. They check off all the essentials—good sound, long battery, smart features—and throw in bonuses like gaming mode and fast charging to sweeten the deal.
It’s rare to find earbuds at this price that don’t feel “cheap” in either design or performance. Boult has managed to craft something that feels premium where it matters most, and that’s why the Z40s are quickly becoming a favorite among value-conscious users in India.
