Fight Club Campus Flex Combo 2 — OnePlus Nord Buds 3r + Baseus Comet 20000mAh

This is the combo for people who don’t want to think about battery. Ever. A 20000mAh power bank paired with earbuds that already last all day means you can leave home Friday morning and not worry until Sunday.

The Fight Club Campus Flex Combo 2 pairs the OnePlus Nord Buds 3r true wireless earbuds with the Baseus Comet Series 20000mAh Power Bank — a ৳4,600 value, priced at ৳3,699 at Marshmallow Tech.

1. OnePlus Nord Buds 3r — True Wireless Earbuds

OnePlus made its name selling flagship behaviour at mid-range prices, and the Nord Buds 3r continues that. It’s built for the way students actually use earbuds — long sessions, noisy environments, and constant gaming.

• Large dynamic drivers — big, energetic sound with deep bass and clear vocals. Tuned for hip hop, EDM, Bangla and Hindi tracks, and anime OSTs.
• Active Noise Cancellation — cuts down bus engine drone, traffic horns, and classroom chatter so you can listen at safe volume and actually hear detail.
• Transparency mode — one tap lets outside sound in, so you can talk to someone or hear an announcement without taking the buds out.
• All-day playtime with the case — one overnight charge covers class, commute, gym, and evening.
• Fast charge — a short top-up gives you hours of playback when you’re already running late.
• AI noise-cancelling call mic — clean, clear voice on online classes, Google Meet, and phone calls even on a busy street.
• Ultra low-latency gaming mode — audio locks in sync with the screen, so footsteps and gunshots land exactly when they should.
• Bluetooth 5.x with dual device pairing — laptop and phone connected at once, switches automatically.
• IP water and sweat resistance — handles workouts and Dhaka rain.
• Customisable controls and EQ — set your own taps and tune the sound through the companion app.

2. Baseus Comet Series 20000mAh Power Bank

Baseus is one of the most respected charging brands globally, and the Comet Series is their practical, high-capacity workhorse. 20000mAh is where a power bank stops being an emergency backup and becomes a portable outlet.

• 20000mAh capacity — roughly four to five full phone charges. Enough for a weekend trip, a full day of travel, or sharing charge with friends.
• Built-in cable design — the Comet series carries its own integrated cable, so there’s nothing to forget and nothing to lose. Pull it out, plug in, done.
• Fast charging output — high-wattage PD/QC delivery that charges modern phones at proper speed, not trickle speed.
• Charges multiple devices simultaneously — phone, earbuds, and a friend’s phone all at once through the built-in cable plus additional ports.
• Fast recharge input — refills the power bank itself quickly instead of taking all night.
• Digital display / LED indicators — see exact remaining battery so you’re never guessing.
• Multi-layer safety protection — over-charge, over-heat, over-current, and short-circuit protection guards your device battery.
• Durable travel-ready build — made to live in a backpack through daily commutes and long trips.
