Sherlock Office Pro Combo — OnePlus Bullets Z2 ANC + Baseus Adaman 20000mAh

If your day runs on back-to-back calls, meetings, and a phone that never gets a break, this is your combo. Active noise cancellation for the calls, a 20000mAh metal-body power bank for everything else.

The Sherlock Office Pro Combo pairs the OnePlus Bullets Wireless Z2 ANC neckband with the Baseus Adaman 20000mAh Power Bank — a ৳5,900 value, priced at ৳4,899 at Marshmallow Tech.

1. OnePlus Bullets Wireless Z2 ANC — Neckband Earphones

The Bullets Z2 ANC takes the legendary Bullets battery life and adds proper active noise cancellation. For anyone spending the day on calls, that combination is hard to beat at this price in Bangladesh.

• Active Noise Cancellation — silences office AC hum, traffic, and open-plan chatter so you can concentrate on a client call instead of straining to hear it.
• Transparency mode — one press lets the room back in when a colleague speaks to you, no need to remove the neckband.
• Enormous battery life — multi-day playback on a single charge. Charge it over the weekend and it carries you through the working week.
• Warp / fast charge — a few minutes on the cable gives you hours of talk time. Ideal when a meeting starts in ten minutes and it’s dead.
• Large dynamic drivers with Bass Boost — deep, full sound for music between meetings, with clean mids for voice-heavy content and podcasts.
• Dual AI noise-cancelling mics — the person on the other end hears your voice, not the street. This is the feature that matters most on work calls.
• Bluetooth 5.x with dual pairing — connected to your laptop and phone simultaneously, switching automatically when a call comes in.
• Low-latency game mode — audio stays in sync when you’re winding down with a game.
• Magnetic control — snap the buds together to pause and disconnect, pull apart to instantly resume.
• IP water and sweat resistance — survives the commute, the gym, and Dhaka rain.
• Lightweight all-day neckband fit — comfortable through an eight-hour shift, and impossible to lose the way single earbuds are.

2. Baseus Adaman 20000mAh Power Bank

The Adaman is Baseus’s premium metal-shell power bank — the one built to sit on a desk and live in a laptop bag for years. This is the power bank people buy once.

• 20000mAh capacity — four to five full phone charges, or enough to top up a phone, tablet, and earbuds across a long day of travel.
• High-wattage PD fast charging — charges modern phones at full speed, and has enough output to top up many USB-C laptops and tablets. This is not a trickle-charge power bank.
• Digital LED display — shows exact remaining percentage and live output wattage, so you always know what it’s doing.
• Multiple ports (USB-C + dual USB-A) — charge three devices at the same time. Your phone, your neckband, and a colleague’s phone.
• Fast recharge input — refills itself quickly overnight instead of taking all night and half the morning.
• Premium aluminium alloy shell — solid, professional finish that dissipates heat better than plastic and survives daily bag life.
• Multi-layer safety protection — over-charge, over-heat, over-current, over-voltage, and short-circuit protection.
• Airline-friendly, travel-ready — within carry-on capacity limits for domestic and international flights.
