Fight Club Campus Flex Combo — OnePlus Bullets Z3 Neckband + Hoco DB22 Power Bank

Fight Club Campus Flex Combo — OnePlus Bullets Z3 + Hoco DB22 Power Bank

Some people want earbuds. Some people want a neckband that never falls out, never gets lost, and lasts the entire day on one charge. If you’re the second type, this combo was built for you.

The Fight Club Campus Flex Combo pairs the OnePlus Bullets Wireless Z3 neckband with the Hoco DB22 power bank — a ৳3,600 value, priced at ৳3,499 at Marshmallow Tech.

1. OnePlus Bullets Wireless Z3 — Neckband Earphones

OnePlus built its reputation on doing more than the price suggests, and the Bullets Z3 is the clearest example in the audio lineup. This is the neckband that students and young professionals in Bangladesh keep coming back to.

• Massive battery life — a full multi-day charge cycle on normal use. Charge it on Friday, forget about it until the middle of the week.
• Warp/fast charge support — a few minutes plugged in gives you hours of playback. Perfect for the moment you realise it’s dead five minutes before leaving home.
• Large dynamic drivers — deep, powerful bass with clear mids. Built for people who actually want to feel the low end in hip hop, EDM, and anime OSTs.
• Bass Boost mode — one switch for extra punch when the track calls for it.
• AI noise-cancelling mic — filters background noise on calls so your voice carries clearly on a busy Dhaka street or in a crowded classroom.
• Bluetooth 5.x with low-latency gaming mode — audio stays in sync while you play, no lag between the tap and the sound.
• Magnetic control — snap the earbuds together to pause and disconnect, pull them apart to instantly resume and reconnect.
• IP water and sweat resistance — handles gym sessions, cycling, and rain without complaint.
• Lightweight flexible neckband — sits comfortably all day, and never gets lost the way single earbuds do.
• Dual device pairing — connected to your laptop and phone at the same time, switches automatically.

2. Hoco DB22 — Compact Power Bank

Hoco is one of the most trusted accessory brands in Bangladesh for everyday reliability. The DB22 is the pocket-sized backup that keeps your phone alive through the second half of the day.

• Compact, lightweight body — fits in a jeans pocket, side pouch, or small sling bag without adding weight.
• Reliable emergency top-up — brings a dead phone back to full usable battery so you make it home with maps, bKash, and ride apps working.
• Multi-device charging — tops up your phone, your neckband, and any other USB device.
• Built-in safety protection — over-charge, over-current, and short-circuit protection keeps your phone battery healthy long-term.
• Battery level indicator — know exactly how much backup you have before you head out.
• Durable everyday build — designed to be thrown into a bag every single day and keep working.
