boat Rockerz 333 ANC Wireless Neckband Earphone

boat Rockerz 333 ANC – DIRAC Opteo + ENx + 25dB ANC at ৳3,200

The boat Rockerz 333 ANC is built around a professional audio partnership: DIRAC Opteo™ technology, co-developed with Dirac Research — a Swedish audio science company whose algorithms are used in premium products from Sony, BMW, and B&O. The Rockerz 333 ANC applies Dirac’s audio optimization algorithms to its 13mm drivers for Crystal Bionic Sound that’s more scientifically tuned than self-tuned budget alternatives. Combine this with 25dB ANC, boat’s ENx™ call noise cancellation, ASAP fast charging, a braided cable, and 24-hour battery — and the 333 ANC is boat’s most technically sophisticated neckband available in Bangladesh.

🔬 DIRAC Opteo™ — Professional Audio Science in a Budget Neckband

Dirac Research is not a marketing partner — they are one of the world’s leading audio science companies with genuine acoustic engineering expertise. Their Opteo technology analyzes the physical acoustic characteristics of the earphone design and applies correction algorithms to produce more linear, accurate frequency response. In plain terms: the 333 ANC’s 13mm drivers have been professionally tuned by audio scientists to sound as accurate as possible within the constraints of the hardware. This is a meaningful differentiator from earphones tuned by marketing teams rather than engineers.

⚡ ASAP Charge — 5 Minutes to 5 Hours

boat’s ASAP (Android Smart Audio Protocol) charge technology delivers 5 hours of playback from just 5 minutes of charging. Plug in while you’re putting on your gym clothes, unplug when you’re ready to go — and you have your entire workout covered from a single 5-minute plug-in. Full charge in under an hour.
