The Boult Astra (sold as GOBOULT Astra) is a budget truly wireless earbud aimed at mobile gamers and people who want earbuds that look a little different. Boult rates it for 48 hours of total playtime with the case, a 45ms Combat Mode for low-latency gaming, quad-mic ENC for calls and 13mm drivers, plus LED lighting. It is a reasonable pick if you want gaming-friendly earbuds with some visual flair, but it has no active noise cancellation, and a few features on the Amazon listing are not confirmed on Boult’s own page.
A note on how this article was put together: it is based on Boult’s official Astra product page and the Amazon.in listing, both checked on 17 October 2026. It is not a hands-on review, and we did not find an independent published review of the Astra to cite for sound or battery performance, so we do not make claims about how it sounds or how long it lasts in practice.
The Amazon link in this article opens the White Opal colour listing. Boult’s own store lists the Astra in Black, Smoky, White and Powder Blue, so check the colour name and photos on Amazon before you order.
The short answer
- Good for: casual mobile gamers, students and anyone who wants splash-resistant everyday earbuds with LED styling
- Not for: people who need active noise cancellation, very long total battery life or confirmed multipoint pairing
- What stands out: 45ms Combat Mode, quad-mic Zen Mode ENC, AAC support, IPX5, customisable touch controls, made in India
- What holds it back: no ANC, 48 hours total is modest next to some Boult siblings, app support is claimed by Amazon but not described by Boult, and no independent review data was available to us

Boult Astra vs Boult Z40 Pro: what actually changes
Buyers often land on the Astra while also looking at the Boult Z40 Pro, because the two share a lot. Both official pages list 13mm drivers, Bluetooth 5.3, AAC and SBC, a 45ms low-latency mode, quad-mic ENC and an IPX5 rating. The differences are in battery, lighting and controls.
| Feature | Boult Astra | Boult Z40 Pro |
|---|---|---|
| Total playtime | 48 hours | 100 hours |
| Fast charging | 10 min for 100 min | 10 min for 120 min |
| LEDs | Mode Sync LEDs | Not listed |
| Touch controls | Customisable (per Boult FAQ) | Fixed gestures listed |
| Bluetooth | 5.3 | 5.3 |
| Latency mode | 45ms | 45ms |
| Water resistance | IPX5 | IPX5 |
In plain terms, the Z40 Pro is the battery-first choice and the Astra is the style-first choice. If you rarely remember to charge your gadgets, the Z40 Pro’s larger total is the bigger deal. If you care about the LED look and being able to change what taps do, the Astra makes more sense.
Battery life: what 48 hours means in practice
The 48-hour figure covers the Boult Astra and the charging case together. It is not the time you get from the earbuds in one sitting. Boult does not say how many hours the buds last before they need to go back in the case, which is the number that matters on a long flight or a day of back-to-back calls. Until a reliable test is published, treat single-charge endurance as unknown.
What Boult does state is a fast-charge figure: 10 minutes of charging for 100 minutes of playtime. That is useful if you notice a flat case just before leaving home. Charging is over USB Type-C, so a common Android phone cable will usually do the job.
Also remember that LED lighting draws some power. Boult does not say whether the Astra’s 48-hour rating was measured with the LEDs on, so real-world totals may vary with how you use it.
Combat Mode and gaming latency
Boult’s Combat Mode is a low-latency setting rated at 45ms. Latency is the gap between something happening on screen and the sound reaching your ears. In competitive mobile shooters, a short delay helps footsteps and gunfire line up with what you see, and in video it keeps dialogue in sync with lips.
Keep expectations realistic. A latency figure like 45ms is the manufacturer’s best case. The Boult Astra’s Bluetooth hardware, the codec in use and interference from other wireless devices can all add delay. Without an independent latency test for the Astra, the 45ms figure is Boult’s claim rather than a verified result.
Calls with Zen Mode quad-mic ENC
The Astra uses four microphones for what Boult calls Zen Mode Environmental Noise Cancellation, and Boult’s FAQ promises HD call clarity. ENC focuses on your voice: it tries to filter out background noise picked up by the microphones so the person on the other end hears you better.
ENC is not active noise cancellation. It does not cut the traffic or engine noise you hear while listening to music. Any quiet you get comes from how well the ear tips seal your ear canal. If blocking outside noise on a metro or flight is a priority, you need an ANC model such as those in the alternatives section below.
Sound: what Boult claims and what is unknown
Boult says the Astra’s 13mm Boom X Tech drivers deliver strong bass through its BoomX tuning, and the FAQ pitches it at bass lovers. Large drivers can move more air for low-frequency punch, but driver size alone does not decide sound quality. Tuning, ear-tip fit and the codec matter just as much.
We could not find an independent published review of the Astra to describe its tonal balance, so we will not guess. If you prefer a neutral sound, it is worth checking whether the app support mentioned on the Amazon listing includes an equaliser before you buy. AAC support is a plus for iPhone users, while SBC covers every other Bluetooth source. No high-resolution codec such as LDAC is listed.
LEDs, app support and controls
This is where the Amazon listing and Boult’s product page do not quite match. The Amazon title mentions Breathing LEDs and Built-in App Support. Boult’s own Astra page lists Mode Sync LEDs without describing how they behave, and it does not mention an app at all as of 17 October 2026. Boult does have a companion app called GOBOULT Amp, which it names on other models such as the Mustang Torq, but its page does not confirm Astra support.
On controls, Boult’s FAQ says the touch controls are customisable for play or pause and track skipping. The page does not say whether volume can be controlled from the Boult Astra, and it does not list dual-device connection. If either matters to you, check the Amazon listing details and recent customer questions before ordering.
The Astra carries an IPX5 rating, which covers sweat and splashes. It is fine for the gym or light rain, but the Boult Astra should not be submerged or rinsed.
Is the Boult Astra right for you?
- Yes, if you play mobile games and want a dedicated low-latency mode at a budget level
- Yes, if you like LED styling and want to remap touch gestures
- Yes, if you take calls outdoors and want multi-mic ENC
- No, if you need active noise cancellation for travel or a noisy office
- No, if battery life is your top priority, in which case Boult’s own Z40 Pro is rated for more than twice the total playtime
- No, if you need officially supported multipoint pairing between a phone and a laptop
Other earbuds to consider
Boult Z40 Pro
The same core features as the Astra (13mm drivers, Bluetooth 5.3, 45ms mode, quad-mic ENC, IPX5) with a much larger 100-hour total playtime rating and faster 10-minute top-ups. It skips the LED styling.
Boult Mustang Torq
Another Boult gaming-leaning model. Boult lists 13mm drivers, Bluetooth 5.4, 50 hours of total playback, 45ms Combat Mode, quad-mic ENC, IPX5, Mode Sync LEDs and support for the GOBOULT Amp app on its official page.
OnePlus Nord Buds 3
The pick if you want real noise cancellation. OnePlus lists up to 32dB ANC, a 12.4mm driver, Bluetooth 5.4, dual connection and up to 43 hours of playback with the case with ANC off. See our OnePlus Nord Buds 3 review for more.
Before you place the order
- Confirm the colour on the listing. Our link opens White Opal, and Amazon may show a different default colour on some visits
- Check that the title says Astra and the specifications match 48 hours, 45ms and 13mm drivers
- Look for app details in the listing if an equaliser or gesture customisation matters to you
- Buy from Boult’s storefront or a well-rated seller and keep the invoice for Boult’s 1-year warranty
- Register the product on Boult’s warranty page, which Boult links from its site
- Check the listing for box contents such as extra ear-tip sizes and a USB Type-C cable, since Boult’s page does not list them
Once you have checked those points, see the GOBOULT Astra in White Opal on Amazon.in.
Frequently asked questions
Does the Boult Astra have ANC?
No. The Boult Astra has quad-mic Environmental Noise Cancellation in Zen Mode, which reduces background noise picked up during calls. It does not actively cancel outside noise while you listen to music.
What is the battery life of the Boult Astra?
Boult rates the Astra for 48 hours of total playtime including the charging case, with a 10-minute charge giving 100 minutes of playback. Boult does not publish how long the earbuds last on a single charge.
Is the Boult Astra good for gaming?
It is designed with gaming in mind. Boult claims 45ms latency in Combat Mode, which should suit casual mobile gaming. We found no independent latency test to confirm the figure, and real latency also depends on your phone.
Does the Boult Astra have an app?
The Amazon listing says it has app support, but Boult’s official Astra page does not mention an app as of 17 October 2026. Check the listing details before buying if app features matter to you.
What is the difference between the Boult Astra and the Z40 Pro?
Both have 13mm drivers, Bluetooth 5.3, 45ms low latency, quad-mic ENC and IPX5. The Astra adds Mode Sync LEDs and customisable touch controls, while the Z40 Pro is rated for 100 hours of total playtime against the Astra’s 48 hours.
Bottom line
The Boult Astra is a sensible budget choice for gamers who want a low-latency mode, decent call features and LED styling, as long as they do not need ANC or class-leading battery totals. Its biggest unknowns are real-world sound and single-charge battery life, which no independent review we found has covered. If it fits your needs, check the current price of the Boult Astra on Amazon.in.
