GOBOULT Mustang GT20 review: Big sound, party vibes

Rating: 3.5/5

The budget Bluetooth speaker market in India is crowded. You walk into any electronics store or scroll through any online marketplace, you will find dozens of options sitting in the sub-Rs 3,000 bracket – all promising powerful bass, long battery life and premium design but very few get all three right at the same time.

At a starting price of Rs 2,999 (Turbo Black) and Rs 3,499 (Turbo Ice), the GOBOULT Mustang GT20 enters this space with a 20W output, RGB lighting, Bluetooth 6.0 and a design that is starkly related to the automotive aesthetic. We used it during music and movie sessions, and casual outdoor use over several days to find out whether it earns its place on the shelf.

Design and Build: Punchy looks

The white colour option of the Mustang GT20 gets a gold perforated mesh grille with metallic finish, rugged look and an LED-fitted base, offering more appeal than most speakers lack.

It looks like a desktop table audio accessory and it does that job reasonably well. The build quality feels solid for the price as there is no flex in the casing, the grille does not rattle when you press on it and the overall weight gives the speaker a sense of substance.

The RGB lighting strip runs along the base, and comes with multiple style modes, including one that syncs loosely with the beat of whatever is playing. In practical occasions like in a darkened room at a small gathering, it adds ‘glow’ to the atmosphere.

There is no option to turn the lights off without powering down the speaker, which may bother users who want the audio without the visual show. We did not find the LEDs ‘too much’ and appreciate the subtle touch.Controls are handled through a single joystick on the top panel that also manages playback, volume and track changes. It also handles call pickup and hang-up for hands-free calling. The joystick works well enough in practice, and adds to the cluttered-button design.

The Type-C charging is a welcome inclusion at this price point, and the speaker accepts USB drives and TF cards for offline playback alongside Bluetooth.

Audio performance: Loud but lacks bass

At 20W RMS, the GOBOULT Mustang GT20 sits at the upper end of what this price bracket typically offers, and the output does show. The speaker gets genuinely loud without losing composure even at 90% volume. The dual dynamic drivers handle the mid and high frequencies, and while low frequency (bass) is present, it lacks physical impact and resonance – essentially creating a flat, stationary and dull feeling instead.For example, when we listened to “I See You (feat. Billy Raffoul) by Kygo”, the punch on the bass drum was audible but that kick that you expect from a speaker with 20W output was missing, making it a bit muddy, especially at higher volume levels. There’s also a positive side: Those who do not want the bass to be overwhelming the mids or highs will likely appreciate this sound signature. Testing with Bollywood tracks Arijit Singh’s “Sitaare” (from the film Ikkis ) and Vishal Dadlani’s “Hum Dono” as well as trending songs like “Saiyaara” and dance number “Ban Ke Dikha.”

The vocals came through clearly and were not overwhelmed by the bass. The mid-range held up well, and the stereo separation – while not particularly wide – gave tracks enough space to breathe.

Switching to electronic and dance music, like Wait So Long by Swedish House Mafia, had enough energy and beat definition to work well at a small gathering. The bass radiator contributes noticeably to the low-end weight here, giving kick drums good presence.Softer genre like downtempo, ambient and chillout also held up reasonably well. Take Breathe (Suduaya Remix) and Touchdown Goa (Suduaya) for example, which remained true to their trademark warmth and bassy undertones, creating a lush, multi-layered soundscape with a silky low-end that was there but didn’t overshadow the fragile mid-range.Movie and web series use worked well for casual sessions. Dialogue remained clear and audible, and the wider soundstage the GT20 produces compared to phone or laptop speakers made content like action sequences and background scores feel noticeably more immersive.

Bluetooth 6.0 is one of the GT20’s stronger selling points. Pairing on first use took seconds, and subsequent reconnections were automatic and fast. The connection held reliably across a standard room and through one interior wall.

Battery life

The battery backup is subject to usage and habits. GOBOULT rates the GT20 at up to seven hours of playback, and real-world use came in broadly in line with that figure under moderate conditions.

At 60% volume, the speaker consistently delivered between 5-6.5 hours before the low battery indicator kicked in. Seven hours is enough for a full day of background listening, a long outdoor session or a casual evening gathering.

Verdict

At a price starting at Rs 2,999, the GOBOULT Mustang GT20 gets more right than wrong for a speaker at its price point. The 20W output delivers genuine volume without immediate distortion, the bass radiator adds low-end weight but could have been better and Bluetooth 6.0 connectivity is reliable. The RGB lighting gives it a visual identity that suits the party-speaker positioning. For those looking for a capable, characterful and genuinely loud portable speaker without spending significant money, the GOBOULT Mustang GT20 makes a reasonable and honest case for itself.
