The Boult Audio Curve Max review is here, and if you’ve been looking for a budget-friendly neckband with bold promises, this one probably caught your attention. With features like 100 hours of playtime, boosted bass, and clear calling, it sounds like a dream deal—especially for under ₹1,200. But the real question is: does it actually deliver?
On paper, Boult claims this neckband offers powerful sound, crystal-clear calls, and enough battery to last for days without charging. But we’ve all seen brands hype things up before. So in this review, I’ll share my real-life experience using the Curve Max for music, calls, daily wear, and even gym sessions.
We’ll dive into the design, comfort, sound quality, battery backup, and mic performance. By the end of this review, you’ll know exactly whether the Boult Audio Curve Max is a smart buy—or just another oversized promise.
That’s when I realised this review couldn’t just focus on battery numbers; it had to dig into comfort, mic clarity, and how the bigger 13 mm drivers handle bass at high volume. What follows is the good, the quirky, and the deal‑breakers—so you can decide if the Curve Max is the marathon neckband Boult claims or just another oversized promise.
Take your audio experience to the next level with the Boult Audio Curve Max. Its 13mm magnetic bass drivers deliver deep, immersive sound, while 50ms low-latency gaming mode keeps every beat and movement perfectly synchronized. With up to 100 hours of playback, this neckband keeps your music and calls going without interruption.
Stay effortlessly connected with Bluetooth 5.3 and dual-device pairing. The Zen ENC mic filters background noise for crystal-clear calls, and Type-C fast charging gives 24 hours of playback from just a 10-minute charge. Boult Curve Max combines endurance, precision, and convenience in one sleek design.
First Impressions – Solid Start for the Price
The packaging is fairly minimal, and once you unbox the Curve Max, you’ll notice it’s slightly bulkier than some other neckbands—but not in a bad way. The band is flexible and feels durable, not the kind of plastic that snaps if you twist it a little.
The earbuds have magnets, which help prevent them from tangling when not in use. It’s a small feature, but honestly, one I’ve come to appreciate during commutes.
Color choices are subtle—mostly black with metallic accents—but it looks decent, especially for its price bracket.
Sound Quality – Big Bass, Big Personality
Let’s talk about the real reason you’d even consider this: the 13mm drivers. If you like bass—and I mean really like it—you’ll enjoy what the Curve Max brings to the table. It’s tailored for high-energy music like Bollywood hits, EDM, and hip-hop. Songs like “Tum Tum” or “Blinding Lights” absolutely pop with this.
Vocals are generally clear, although sometimes the bass does overshadow mid-tones, especially on more acoustic or vocal-heavy tracks. Treble is there, but don’t expect super crisp highs. It’s not studio-grade, but it’s very enjoyable for casual listening.
If I had to sum it up: this is a “fun” sound signature, not a “flat” or “neutral” one.

Listening Takeaway
Curve Max pumps serious low‑end with its 13 mm drivers—great for EDM and Bollywood bass drops. Mids stay clear up to ~85 % volume; highs roll off slightly, so long sessions aren’t fatiguing. Mic quality indoors is clean; outdoors, the AI‑ENC quiets engine noise but struggles with gusty wind.
Battery Life – This Thing Just Keeps Going
Okay, this one’s no joke. 100 hours of playback is not just a marketing gimmick—it really does last forever. I charged it once on Monday, used it for a few hours each day, and by Sunday, I still had juice left. That’s with daily use.
What’s even better? A 10-minute charge gives you up to 15 hours of playback. That’s saved me more than once when I forgot to plug it in before heading out.
Standby time is excellent too. If you forget it in your bag, it’ll still be alive days later.
I pushed the Curve Max through 5 days of mixed use (total playtime ≈ 27 hrs) before it dipped below 20 %. A 10‑minute top‑up on a 33 W charger netted 14 hrs more music—impressive for Micro‑USB, though I still wish Boult moved to Type‑C.

Call Quality – Clear Enough for Daily Use
This is where the dual mics with ENC come in. I’ve used it for a few Zoom calls and a bunch of phone conversations. Indoors, it’s quite good—voices are clear and background noise is reasonably muted.
Outdoors, it handles mild traffic or café noise well. It won’t compete with high-end ENC headphones, but it’s better than expected at this price.
Connectivity & Features – Stable and Smart
Bluetooth 5.3 is the latest spec, and it shows. The connection is rock-solid. I paired it with both my phone and laptop using dual pairing, and switching between them felt seamless. No lag while watching videos or joining video calls either.
Just take it out, tap the button, and you’re ready to go. It remembers your last connected devices, so reconnecting is basically instant.
Dual‑device pairing worked flawlessly—switching between my laptop’s Teams call and phone’s Spotify in under three seconds. The neckband also supports low‑latency gaming mode; footstep audio in BGMI felt synced enough for casual play, though competitive gamers might notice slight delay.
Comfort & Fit – Mostly Great, With One Catch
The neckband itself is soft and flexible, which makes it comfortable to wear for hours. I’ve worn it during long walks, even during a gym session, and it stayed secure the whole time.
The only downside? It’s slightly heavier than super-slim neckbands, so after a long day, you might feel it around your collar. But for me, the tradeoff is worth it considering the battery and features packed in.
Real‑World Fit Notes
- The wider silicone band looks chunky but actually balances weight well; feels secure during HIIT burpees.
- Magnets snap firmly—no surprise detachments while walking.
- Ear‑tips run slightly large; swapping to the small size improved seal and bass for me.
Amazon user’s voice: “Wore it for three straight hours in the office—no neck strain, magnets keep buds tidy.” — ★★★★☆
Water Resistance – Safe for Sweat & Sprinkles
With an IPX5 rating, the Boult Audio Curve Max is ready for your workouts and morning runs. I’ve worn it during sweaty cardio sessions, and it held up without issue. Just don’t jump into a pool with it, obviously.
