Boult Audio, a homegrown consumer technology brand, has a great selection of TWS earbuds. We just reviewed the new Boult Z40 Ultra earphones and were rather pleased with the audio quality considering the cost. They provide 10mm drivers with BoomX Technology, feature low-latency gaming mode with a maximum latency of 45ms, and deliver up to 32dB of active noise cancellation (ANC). They also include dual pairing capabilities and an IPX5 designation for water resistance. They are providing a lot at this price, but the important question is how well they work. After using them for more than a month, this is our review.

Boult Z40 Ultra Review: Design
The case features a dual glossy and matte appearance and is entirely composed of high-quality plastic. It features horizontally positioned LEDs that light up in green to indicate the amount of battery life left, as well as the Boult logo on the front. The Z40 Ultra has a metallic rim and a premium finish.
You should have no problem putting the tiny, pebble-shaped charging case into your pocket while not in use. The earbuds’ plastic casing is resilient enough to withstand unintentional falls. The buds and case are of nice quality, however, handle them carefully as they are somewhat slippery.
The Boult Z40 Ultra charging case is built without buttons. The glossy side attracts a lot of scratches. While the matte finish helps cover up any scratches. For charging the case, there is a USB-C port at the bottom. In the package, Boult includes a USB-C cable.
The budget-friendly earphones have four colour options: Black, Beige, Blue, and Brown. The colour option we have for testing is black.
As you can see, the earbuds are firmly planted into the respective slots on the left and right. The earbuds’ housing contains magnets that hold them in place.
The earbuds are shaped like a stem and fit well in the ear canal. They come with silicone ear tips that slide right into the canal. For a snug fit, these come with an additional pair of ear tips. Furthermore, it features a dusty mauve flat touch panel for music control and playback pause. The earphones are quite light and cosy to wear for long periods.
However the earbuds are not very comfortable to wear while you sleep, and if you use them for a long time, you might get pain and irritation in your ears. The device’s IPX5 classification protects it from water splashes, so you can use it anytime, even in the gym or when working out in the rain.

Boult Z40 Ultra Review: Performance
BoomX-enabled 10mm drivers are included with the Z40 Ultra. The snug fit provides excellent noise cancellation when conversing on the phone or enjoying music. You may personalise your audio experience using 3EQ modes- HIFI, Rock, and Bass settings. The user can adjust the volume on their mobile as there are no options for volume control on the earbuds.
This one allows for the full range of frequencies to be heard without the need for further effort, unlike most others where the bass is too high and the treble, mids, and volume automatically diminish. The whole listening experience is outstanding. Moreover, the loudness is accurately adjusted, neither too high nor too low.
Even though these aren’t made solely for gaming, we tested them to see if they work well for gaming. With its ultra-low 45ms latency and Combat Gaming Mode, the Z40 Ultra gives you an edge over others. There was not much audio lag when playing intensive games like Call of Duty. However, latency is not an issue with light games.
By eliminating background noise during calls, Boult Z40 Ultra’s 32 dB active noise cancellation technology in the Zen Quad Mic ENC offers crystal-clear calls even in the noisiest of settings. The Z40 Ultra has a four-mic setup that makes it easy to capture the words you speak. According to Boult, AI technology is integrated into these buds.
AI-driven intelligent speech processing is incorporated into the company’s Sonic Core Dynamics solution for optimal noise cancellation and low power consumption. Prism Voice PLC is another AI tool that guarantees lag-free chats, immersive game interaction, and improved call quality for smooth virtual meetings.

Bluetooth connectivity is really good. The Boult Z40 Ultra headphones support Bluetooth 5.3 and have a wireless range of roughly 10 metres. But perform flawlessly within a 20 to 24-foot radius when there are obstructions. You may easily switch between two devices with a single swipe thanks to Dual Device Pairing’s ease.
According to Boult, a single charge of the Z40 Ultra can provide up to 100 hours of playback time. To guarantee that the user can always carry the earphones while travelling, it also features a Type-C connector for fast charging. For longer use without the need for frequent recharging, the 100-hour playtime makes it perfect for everyday commuting or long journeys.
Verdict
The ANC offered at this price range is sufficient to judge Boult Z40 Ultra’s performance, and the answer is that it functions and isn’t a gimmick. However, the battery will run out faster with the ANC. They successfully filter out outside noises with 32dB Active Noise Cancellation, resulting in a rich audio experience.
Packed with a stylish design, the Boult Audio Z40 Ultra Truly Wireless Earbuds offer an amazing range of features. If you’re on a tight budget and want a high-quality product in this price range, just go for it.
