JBL Quantum 100 is available at Mascom International for KSh 6,000, a wired over-ear gaming headset with 40mm drivers, a detachable boom mic and a single 3.5mm plug. Units on our shelf are brand new and sealed. The JBL Quantum 100 weighs 220 grams, covers the full 20Hz to 20kHz range people can hear, and runs on a 1.2-metre cable with no battery to charge. One plug connects it to a PS5 controller, an Xbox controller, a Nintendo Switch, a laptop or a phone. Pick one up at the Old Mutual Building on Kimathi Street in Nairobi CBD.
Built for university students, mobile gamers and first-time console owners across Kenya, the JBL Quantum 100 solves a common problem. Phone and laptop speakers leak sound into the room, and a laptop mic picks up every fan, voice and matatu horn outside the window. The directional boom mic sits close to your mouth, so teammates on Discord and lecturers on Zoom hear you instead of the room. Take the mic out and the JBL Quantum 100 becomes plain headphones for music on the walk from a Kenyatta University hostel to class.
Where most Nairobi electronics shops sell unbranded headsets at this price with no guarantee, Mascom International stocks the genuine JBL Quantum 100 with a 12-month warranty and a walk-in store you can return to. Customers across Nairobi tell us it is the headset they buy for a teenager's first PS5 or a student's laptop, because one cable covers both. Come to Kimathi Street and try the fit before paying, or order on WhatsApp for pay-on-arrival delivery anywhere in Kenya, same day within Nairobi. The JBL Quantum 100 is the entry point to our JBL Quantum stock.
Common Questions About the JBL Quantum 100
How much is the JBL Quantum 100 in Kenya?
The JBL Quantum 100 costs KSh 6,000 at Mascom International in Nairobi CBD, brand new and sealed. That price includes the headset, the detachable boom mic with its foam windshield, and a 12-month warranty handled at our Kimathi Street store. Delivery is pay-on-arrival, so you check the box before you hand over cash or send M-Pesa. If you want bigger 50mm drivers and a USB adapter for PC surround effects, the JBL Quantum 300 sits KSh 2,500 higher at KSh 8,500.
Does the JBL Quantum 100 work with PS5, Xbox, Nintendo Switch and phones?
Yes, JBL lists the JBL Quantum 100 for PS5, PS4, Xbox Series X, Xbox Series S, Xbox One, Nintendo Switch, PC, Mac, mobile and VR. It connects through one 3.5mm plug, so on PlayStation and Xbox it goes into the controller's headset jack. On a Switch it plugs into the console itself, which means handheld play works too. Phones need a 3.5mm port or a USB-C to 3.5mm adapter, since many newer phones have dropped the headphone jack.
JBL Quantum 100 or JBL Quantum 300: which one should you buy?
Buy the JBL Quantum 100 if you play mainly on console or phone, and pick the JBL Quantum 300 if you game on a Windows PC. The JBL Quantum 300 moves up to 50mm drivers from 40mm, adds a USB audio adapter that unlocks JBL QuantumSURROUND on PC, and uses memory foam cushions, for KSh 8,500. The JBL Quantum 100 is lighter at 220 grams against 245 grams, its mic detaches fully instead of flipping up, and it saves you KSh 2,500.
Will the JBL Quantum 100 keep working during a KPLC power cut?
Yes, the JBL Quantum 100 has no battery, so it works for as long as the device it is plugged into has charge. During a KPLC outage in Kasarani or Rongai, you can keep listening on your phone or on a laptop running on battery, with no headset to recharge. The same design means there is no cell inside to wear out after two or three years. The trade-off is the 1.2-metre cable, which keeps you within arm's reach of your controller or laptop.
Is the JBL Quantum 100 mic clear enough for Discord and online classes?
The JBL Quantum 100 uses a directional voice-focus boom mic, which favours sound from in front of your mouth over sound from the sides. That helps in a shared hostel room or a busy family home, where a laptop mic would catch every conversation nearby. It has a mute feature for moments you need silence, and the foam windshield in the box softens breath noise. Students at the University of Nairobi tell us it handles Google Meet group calls without the echo laptop speakers cause.
Is the JBL Quantum 100 comfortable for long gaming sessions?
At 220 grams, the JBL Quantum 100 is light enough for a two- or three-hour session without a sore neck. It is an over-ear design, so the cushions sit around your ears rather than pressing on them, and the ear cup opening measures 6.1 by 4.9 centimetres. On warm Nairobi afternoons any closed over-ear headset gets warm, so short breaks help. If you wear glasses, try it on at our Kimathi Street store first, because fit differs from head to head.
Is the JBL Quantum 100 a good first gaming headset for a child?
Yes, the JBL Quantum 100 suits younger players because it is light and has nothing to charge or pair. The boom mic lifts out, so a parent can remove it when voice chat with strangers is not wanted. There is no software to install on the PS5 or Switch; the console detects it once plugged in. Volume still needs a parent's eye: set the console's headset volume limit, because any closed headset can be played too loud for young ears.
Who should buy the JBL Quantum 100 and who should skip it?
Buy the JBL Quantum 100 if you want a genuine wired gaming headset for console, Switch or phone at KSh 6,000. Skip it if you dislike cables, if you game on a Windows PC and want surround effects, or if you mostly listen to music on the go. Wireless gamers should look at the JBL Quantum 350 Wireless at KSh 11,000. Commuters who want music headphones should consider the JBL Tune 720BT at KSh 6,500, a Bluetooth pair built for listening rather than team chat.
Technical Specifications
Audio Hardware
- 40mm dynamic drivers — the speakers inside each ear cup, sized for clear dialogue and solid explosions in games and films.
- Frequency response of 20Hz to 20kHz — covers the full range of human hearing, from deep bass rumble to high footsteps.
- Sensitivity of 96dB at 1kHz and 1mW — gets loud from a phone or controller jack without any external amplifier.
- Impedance of 32 ohms — a low figure, so phones, laptops and controllers drive it easily at normal listening levels.
- Closed over-ear design — the cups seal around your ears, keeping game sound in and some room noise out.
- Stereo tuning for games — left and right channels stay distinct, so you can tell which side a car or footstep comes from.
Microphone and Voice Chat
- Detachable voice-focus boom mic — a directional microphone that picks up your voice more than the noise around you.
- Mute feature — silence yourself quickly when someone walks into the room in the middle of a match.
- Foam windshield in the box — slips over the mic to soften breathing and the hard pop of P and B sounds.
- Removable design — pull the mic out and the headset works as regular wired headphones for music or videos.
- Voice apps — works with Discord, Zoom, Google Meet and in-game party chat on any device with a headset jack.
- Close-to-mouth position — the boom keeps the mic a few centimetres from your lips, so you can speak softly late at night.
Connectivity and Platform Compatibility
- Single 3.5mm plug — the standard headphone connector found on controllers, laptops, the Switch and many phones.
- PlayStation 5 and PlayStation 4 — plug into the DualSense or DualShock controller for game sound and party chat.
- Xbox Series X, Xbox Series S and Xbox One — connects through the controller's 3.5mm jack; JBL lists all Xbox models.
- Nintendo Switch — plugs into the console's own jack, so it works in handheld, tabletop and docked play.
- PC, Mac, mobile and VR — all listed by JBL; phones without a jack need a USB-C to 3.5mm adapter.
- 1.2-metre cable — enough length to run from a controller in your hands or a laptop on a desk to your ears.
Build, Comfort and Durability
- Weight of 220 grams — about the weight of a large phone, light enough for long evening sessions without neck strain.
- Ear cup opening of 6.1 x 4.9 cm — room for most ears to sit inside the cushion rather than pressed under it.
- Outer ear cup size of 10.2 x 8.9 x 2.5 cm — slim enough to rest around your neck between matches.
- No battery inside — nothing to recharge and no cell to lose capacity after a few years of daily use.
- Colours listed by JBL: Black, White and Blue — confirm the colour in stock with us on WhatsApp first.
Controls and Inputs
- Plug-and-play setup — no app, driver or pairing step; the console, laptop or phone recognises it once plugged in.
- Mic mute — JBL builds a mute feature into the boom mic, so you can go silent without leaving the match.
- Detachable mic socket — the boom mic plugs into the ear cup and pulls out by hand, with no tools needed.
- Combined 3.5mm input — one plug carries both game sound and your voice, so most devices need no splitter.
- Older desktop PCs — computers with separate pink mic and green headphone jacks need a standard 3.5mm Y-splitter.
Package Contents
The JBL Quantum 100 box holds everything you need to start playing: the headset itself, the removable boom microphone, a foam windshield for that mic, a Quick Start Guide, a warranty card and a safety sheet. There is no USB adapter or spare cable, because the attached 3.5mm cable is all the headset needs on consoles, phones and laptops. Owners of older desktop PCs with separate mic and headphone ports should add a standard 3.5mm splitter.
Warranty
The JBL Quantum 100 ships with a 12-month warranty through Mascom International, covering manufacturing defects under normal use. That cover includes the drivers, the boom microphone, the cable and the 3.5mm connector. To make a claim, bring the headset and your receipt to our Nairobi CBD service desk at the Old Mutual Building on Kimathi Street.
