Design and build quality of Boult X Mustang Headphones

The Boult X Mustang headphones have a fairly bulky look, especially if you have a smaller face or head, something I personally noticed during use. While they might not come across as very sleek, the matte finish and subtle detailing lend them a slightly premium feel.

The headband is flexible and adjustable, offering a decent fit across different head sizes. The padding on the headband and earcups feels soft, but comfort can vary. In my case, they felt a bit too tight after 20–30 minutes of use, which caused slight discomfort. A short break of 10–15 minutes helped before I could continue wearing them again.

Despite the size, they’re fairly lightweight and fold inward, which adds to their portability. Boult also includes a small cloth pouch for storage. The IPX5 rating means they can handle light splashes or sweat, ideal for short workouts or daily commutes, though we might not recommend using it during rain.

Audio performance of the Boult Headphones

Boult has packed the X Mustang with 40mm drivers, and you can definitely hear the emphasis on bass. If you enjoy thumpy beats and bass-forward tracks like hip-hop or EDM, you’ll find the low-end quite satisfying. That said, the bass sometimes overpowers the mids and highs, especially at higher volumes, where vocals and instruments can lose clarity.

At moderate volume levels, the sound remains fairly balanced for most genres. The 4 EQ modes are easy to toggle through, but the difference between them isn’t drastically noticeable. There’s a slight shift in bass and treble with each mode, but nothing too dramatic.

Sound isolation is decent enough to block out some background noise while commuting or working, but there’s minor sound leakage at higher volumes. In quiet environments, people nearby might hear what you’re listening to.

Overall, the X Mustang delivers punchy audio that suits bass lovers, but audiophiles might find it lacking in refinement.

Boult X Mustang: Call quality and mic performance

The Boult X Mustang comes equipped with a Zen ENC mic, which performs reasonably well for its price. During indoor calls, voice clarity is decent and clear enough for casual chats and quick meetings. Background noise is reduced to an extent.

Outdoors, the mic struggles a bit. Wind noise and traffic can easily seep through, especially if you're in a busy or open area. That said, the person on the other end could still hear me, just with some background fuzz.

In addition, a major drawback I experienced was frequent disconnection during calls. This happened across multiple calls and was noticeable both on mobile networks and apps like WhatsApp.

Battery life and charging

Boult claims a massive 70-hour battery life, and while you won’t be able to keep a track of the number of hours, it still delivers impressive performance. With a combination of music playback, a few calls, and some standby time, I guess I got close to 52–55 hours on a single charge, still solid for this segment.

Charging is handled via Type-C, and it takes around 1-1.5 hours for a full charge. A quick 10–15 minute charge can give you roughly 6–8 hours of playtime, which is great for those in a rush. I didn’t notice any rapid battery draining.

Connectivity and features

The Boult X Mustang offers Bluetooth 5.4, which pairs quickly and stays stable while gaming and listening to music. However, there's no dual pairing, and the low-latency mode doesn’t make a noticeable difference during gaming. The AUX option is handy when the battery dies, ensuring uninterrupted playback anytime.
