While the GoBoult Mustang Sprint was announced earlier this year, I got my review unit a few months later. Personally, it was the Sprint’s design that got me interested in reviewing it in the first place. For starters, it has a partly transparent case and a unique-looking pair of earbuds inside. This should appeal to those of us who want something different and head-turning to wear. But, earbuds are not just about their looks. They need to primarily sound good, the app experience has to be simple and feature-rich, and things like battery life and call quality need to be reliable for everyday use.
Do the GoBoult Mustang Sprint TWS earbuds offer all of these? In my test, here’s what I found out:
GoBoult sent us the yellow variant of the Mustang Sprint earbuds. It is mango-like yellow.
Both the earbuds and the case have black, yellow, silver, white and transparent colour elements. The top portion of the case, i.e., the lid, is transparent, and the bottom half has a carbon-fibre finish. If you don’t like the colour, know that the colour portion faces the ear, and it goes inside the ear.
There is a Mustang logo on the case, not on the earbuds. The buds have ‘302’ imprinted on both sides. I like the design language. One weird thing, though, is that the button on the case only triggers decorative lighting and doesn’t do anything else.
Beyond aesthetics, in everyday use, the GoBoult Mustang Sprint earbuds are comfortable to wear. I didn’t mind wearing it for long hours, both indoors and out. The in-ear fit is tight too, and don’t let the buds fall off with small movements.

Thanks to the IPX5 rating, the earbuds can handle light splashes and sweat without any issues. I even wore them during a drizzle the other day without worrying about water damage. The charging case is compact enough to slip into a pocket or tuck inside a backpack, like when it is raining outside. In time, I will know whether the transparent case withstands drops and scuffs.
You can open the lid with a single hand. The lid closing has a nice clack sound. The buds are also magnetically held in their respective cradles in the case. And for the long-term durability of the case, especially the transparent portion, I will be using them more.
For pairing, the instruction is to take out both the earbuds from the case, and the pairing screen in the GoBoult Amp app should show the buds ready to pair. You just have to tap the Mustang Sprint prompt appearing on this screen, and the buds get paired to the phone. But while trying to connect it to my Pixel 10 and Samsung Galaxy S23, I was getting an error repeatedly. A GoBoult tech support personnel tried to solve this patiently. Didn’t work, though. It may as well be an issue with my review unit.
What worked was pairing the Sprint earbuds with my wife’s iPhone. The Amp app has the standard features, like showing the battery life of the buds and the case, ANC control, equaliser control, and tap controls. The brand has also included tools to clean dust and water ingress with vibration.
The app has some typos, which is a bit odd. To use it, you need to provide your mobile number, and the app’s home screen also asks where the product was purchased. Most users probably won’t mind since they only have to do it once. Still, I mention it because it suggests that some level of user profiling is taking place.
Rest, in everyday use, I didn’t face any other problem. The connection stayed strong, and dual-device connectivity through Bluetooth 5.4 was super convenient. For the second device pairing, you have to disconnect the first device.
As for controls, you get tap to play and pause music, and tap combinations to change the playback. The responses take a second. But they work reliably.
Every time you put on the GoBoult Mustang Sprint earbuds, they play a roaring engine start sound. It was annoying, and I couldn’t find a setting to disable this. Nonetheless, that engine sound tells you the sound is more bassy.
The bass is boomy with a palpable rumble, but it is not very tight. Tracks with low-frequency emphasis, like Cocktail 2’s Mashooqa and Harry Styles’ Dance No More, sound engaging. That said, you can clearly feel vocals, and finer details take a back seat. The bass overshadows the voice, the texture of it, and the instrumental elements in Sobit Tamang’s Dekho Na.
Of course, this may not bother all, and vocal-heavy music and podcasts are all fairly listenable. But if you are looking for a balanced sound signature, you may find the tuning too aggressive. You can try other EQ profiles to find a tuning to your taste. Gamers among you would appreciate Combat Mode with 45ms low latency.
GoBoult advertises up to 32dB ANC on the Mustang Sprint earbuds, which is enough to tune out noises in your working or study environment. You will still hear the voices of people talking nearby, and some sudden noises will creep in. Outside, on busy roads, you will hear some traffic noise. It doesn’t create a fully quiet bubble, but the bubble is quiet enough to let you work or study in focus.
There is no transparency mode, and so while you are out and about or want to listen to someone, you’ll have to remove an earbud.
Call performance also shares the bass-heavy sound for both parties. You can hear what the other person is saying, but the bassiness is not very pleasant.
In our battery test, involving playing a high-res FLAC music file continuously at 80 per cent volume with no ANC, the GoBoult Mustang Sprint TWS ran for 6 hours 45 minutes. It is said to last 60 hours by the brand.
As for charging, the brand claims a 10-minute charge can give up to 100 minutes of playtime. Sprint has a USB-C port, so charging it can be done with the same cable as your phone charger.
The GoBoult Mustang Sprint stands out in a market full of lookalike earbuds. The transparent case, colour accents, and Mustang-inspired styling give it a distinct personality. They are comfortable to wear, offer reliable controls, decent ANC, a 45ms gaming mode, and good battery life. Sound-wise, it is for those who listen to bass-heavy music.
However, there are some compromises worth knowing. The earbuds refused to pair with multiple Android phones I tested and only paired with an iPhone. This could have been a one-off issue with my review unit. Still, it does raise questions about quality control, especially since the problem persisted despite troubleshooting with GoBoult’s support team.
Also, the bass-heavy tuning lacks balance, often pushing vocals and finer details into the background. Call quality is serviceable, but the bass-heavy presentation does not sound particularly pleasant during conversations.
At Rs 1499, the GoBoult Mustang Sprint TWS earbuds make sense for casual listeners who value design and prefer bass-heavy audio. However, if you want a more balanced sound signature or a more polished overall experience, there are other options in this price range.
