Mascom International stocks the JBL Quantum 350 Wireless at KSh 11,000, a cable-free gaming headset that connects through a lossless 2.4GHz USB dongle and runs up to 22 hours per charge. Our units are brand new and sealed. The JBL Quantum 350 Wireless uses 40mm drivers, a detachable voice-focus boom mic and PU-wrapped memory foam cushions, all in a 252-gram frame. JBL lists it for PC, Mac, PS5, PS4 and the Nintendo Switch when docked. See and hear it at Mascom International on the first floor of the Old Mutual Building, Kimathi Street, Nairobi CBD.
Built for PC and PlayStation gamers across Kenya who are tired of tripping over cords, the JBL Quantum 350 Wireless lets you lean back from the desk or play from the sofa without a cable tugging at your head. A dedicated 2.4GHz dongle avoids the audio delay common with Bluetooth headphones, so gunshots line up with the action on screen. Students sharing hostel rooms at JKUAT or Strathmore also avoid a wire stretched across a crowded desk. When the JBL Quantum 350 Wireless runs low, five minutes on charge adds roughly an hour of play before your next match.
Where most Nairobi electronics shops push Bluetooth music headphones as gaming headsets, Mascom International sells the JBL Quantum 350 Wireless as a true gaming set, Discord-certified and covered by a 12-month warranty at our own counter. At Mascom International, we're seeing PS5 owners in South B and Kileleshwa choose it once they realise a wired headset ties them to the controller. Message us on WhatsApp to order with pay-on-arrival delivery, or come to Kimathi Street and wear the JBL Quantum 350 Wireless for a few minutes before you pay.
Common Questions About the JBL Quantum 350 Wireless
How much does the JBL Quantum 350 Wireless cost in Kenya?
The JBL Quantum 350 Wireless is KSh 11,000 at Mascom International in Nairobi CBD, brand new and sealed. The price covers the headset, its USB wireless dongle, a USB-C to USB-A charging cable, the mic windshield and a 12-month warranty claimed at our store. Pay-on-arrival delivery reaches every county, with M-Pesa or cash accepted at the door. It costs KSh 2,500 more than the wired JBL Quantum 300, which is the gap you pay to lose the cable.
Does the JBL Quantum 350 Wireless work with Xbox, phones and the Nintendo Switch?
JBL lists the JBL Quantum 350 Wireless for PC, Mac, PS5, PS4 and Nintendo Switch, but not for Xbox or mobile. On a Switch it works only while the console sits in its dock, because the dongle needs the dock's USB port. Xbox owners should choose a wired headset such as the JBL Quantum 300 instead. Phone gamers should also look elsewhere, since mobile is missing from JBL's compatibility list and we will not promise a connection JBL does not.
How long does the JBL Quantum 350 Wireless battery last?
The JBL Quantum 350 Wireless plays for up to 22 hours on a full charge, according to JBL. A full recharge from empty takes about two hours over USB-C, and a five-minute top-up gives roughly one extra hour. You can keep gaming while it charges by connecting the supplied cable. For a student playing three hours a night, 22 hours works out to about a week between charges, so a Sunday evening charge covers the school or work week.
Can the JBL Quantum 350 Wireless keep going through a KPLC power cut?
Yes, a charged JBL Quantum 350 Wireless keeps playing whatever the mains supply is doing, as long as your PC or laptop stays on. During a KPLC outage in Ruaka or Syokimau, a laptop on battery or a desktop on a UPS keeps the dongle powered. If the headset runs low, a USB power bank can top it up through the USB-C port. Charge it fully before long evening matches so a blackout never ends your session early.
JBL Quantum 350 Wireless or JBL Tune 770NC: which suits a gamer who also commutes?
Choose the JBL Quantum 350 Wireless for gaming at a desk and the JBL Tune 770NC for music on the road. The JBL Quantum 350 Wireless uses a 2.4GHz dongle for low-delay game audio and a boom mic for clear team chat. The JBL Tune 770NC is a Bluetooth headphone with noise cancelling, made for phones, matatu rides and flights, at KSh 9,000. It handles calls and music well but not competitive gaming. PS5 and PC players should take the JBL Quantum 350 Wireless.
Is the JBL Quantum 350 Wireless fast enough for competitive shooters?
Yes for everyday competitive play: the JBL Quantum 350 Wireless uses lossless 2.4GHz wireless through its own dongle, the connection gaming headsets rely on to keep delay low. JBL does not publish a latency figure, but this link avoids the lag Bluetooth adds to games. Plug the dongle into a front USB port with a clear path to the headset for the steadiest signal. Customers across Nairobi tell us gunfire stays in step with the screen in Call of Duty and Apex Legends.
Can the JBL Quantum 350 Wireless cut keyboard noise on Discord?
Yes, on PC the JBL QuantumENGINE software adds AI noise reduction aimed at keyboard sounds, and the headset is certified for Discord. The detachable boom mic is directional, so it favours your voice over the room. It also works with Skype and TeamSpeak. QuantumENGINE adds spatial sound, an equalizer and real-time sound visualisation, but those features stay on the computer. On PS5 and Switch, the mic still carries party chat without the extra processing.
Who should buy the JBL Quantum 350 Wireless and who should skip it?
Buy the JBL Quantum 350 Wireless if you game on a PC or PlayStation and want freedom from cables for KSh 11,000. Skip it if you own an Xbox, since JBL does not list support, or if you play mostly on a phone. Xbox and phone players are better served by the wired JBL Quantum 300 at KSh 8,500. Players who want a higher-tier wireless JBL gaming headset can step up to the JBL Quantum 650 at KSh 27,500, also in our current stock.
Technical Specifications
Audio Hardware
- 40mm drivers — the speakers inside each ear cup, tuned by JBL for clear game effects, voices and background music.
- 20Hz to 20kHz frequency response — the full span of human hearing, from bass thumps to fine high detail.
- 115dB SPL sensitivity at 1kHz and 1mW — plenty of loudness in reserve, so you rarely push the volume near the top.
- 32-ohm impedance — a standard, easy-to-drive figure for headsets, which keeps sound clean at everyday levels.
- Spatial sound on PC — JBL QuantumENGINE places sounds around you through JBL QuantumSURROUND for better positional awareness.
Wireless Connectivity
- Lossless 2.4GHz wireless — a private link through a USB dongle, with less delay than Bluetooth headphones add.
- PC and Mac — plug the dongle into a free USB port; JBL describes the headset as optimised for PC.
- PS5 and PS4 — the dongle plugs into the console, giving wireless game audio and party chat together.
- Nintendo Switch — works while the console is docked, using the dock's USB port for the dongle.
- Xbox and mobile — not listed by JBL, so buyers with those devices should choose a wired headset instead.
- No pairing codes — the dongle and headset are made to work as a set, so setup is plug in and switch on.
Battery and Charging
- Up to 22 hours of play per charge — about a week of three-hour evening sessions before you plug in again.
- Full charge in about 2 hours — plug in before dinner and the headset is ready for the night's matches.
- Fast charge — 5 minutes on the cable gives roughly 1 hour of play when you forget to charge.
- Play while charging — connect the USB cable and keep gaming without losing sound or chat.
- USB-C charging port with a USB-C to USB-A cable — charges from a PC, a wall adapter or a power bank.
- Rechargeable built-in battery — no AA cells to buy, since it tops up over USB-C the same way most phones do.
Build and Durability
- 252 grams — light for a wireless headset that carries its own battery, so long sessions stay comfortable.
- PU-wrapped memory foam cushions — soft against the skin and easy to wipe clean after warm, sweaty play.
- Lightweight headband — keeps pressure off the crown of your head during back-to-back matches.
- Ear cups of 10.2 x 8.9 x 2.5 cm outside and 6.1 x 4.9 cm inside — room for most adult ears.
- Colour: Black, as listed by JBL for this model, so what you see in store is what ships.
- Detachable mic boom — the part most likely to snap on a headset can come off before the headset goes into a bag.
Controls, Microphone and Software
- Detachable voice-focus boom mic — directional pickup that favours your voice; remove it when you only want music.
- Mic mute function — silence yourself in party chat without pausing the game or leaving the lobby.
- Discord certified — it also works with Skype and TeamSpeak for voice calls and community servers.
- JBL QuantumENGINE — AI noise reduction for keyboard noise, an equalizer and sound visualisation, available on PC.
- 1-metre charging cable — long enough to keep playing while plugged into a desktop or laptop on the desk.
- Foam windshield for the boom mic — softens breath noise when you shout callouts during tense rounds.
