BOYA BY-DM100 is in stock at Mascom International, priced at KSh 6,000, a plug-in USB-C microphone that turns an Android phone into a clean voice recorder. The BOYA BY-DM100 carries two condenser capsules set in an X/Y stereo pattern, a 24-bit, 96 kHz digital converter and an 80 dB signal-to-noise ratio, all in a body measuring 67 by 38 by 38 mm. Every unit we sell is brand new and sealed. You can pick one up and test it on your own phone at our Old Mutual Building store on Kimathi Street, in the Nairobi CBD.
Built for journalists, content creators and university students across Kenya, the BOYA BY-DM100 fixes the thin, echoey sound a phone's own microphone records. A reporter covering a press briefing in Upper Hill, an estate agent filming a walkthrough in Kilimani, or a student recording a lecture at Kenyatta University all face the same problem: background noise drowns the voice. The BOYA BY-DM100 plugs straight into the USB-C port and converts sound to digital inside the microphone, so the phone receives a clean signal. There is no battery to charge and no cable to forget in a matatu.
Where most Nairobi electronics shops sell unbranded plug-in mics with no after-sales support, Mascom International stocks genuine BOYA microphones backed by a written warranty. Customers across Nairobi tell us the BOYA BY-DM100 is the easiest upgrade they have made to their phone videos, because it is ready as soon as it is plugged in. The BOYA BY-DM100 suits anyone who records voice notes, interviews or short videos and wants better sound without carrying a camera rig. Visit our Kimathi Street store to hear the difference yourself, or order on WhatsApp for pay-on-arrival delivery anywhere in Kenya.
Common Questions About the BOYA BY-DM100
How much is the BOYA BY-DM100 in Kenya?
The BOYA BY-DM100 costs KSh 6,000 at Mascom International in Nairobi CBD, sold as a genuine, unused unit. That price includes the carry pouch BOYA packs in the box, a 6-month warranty handled at our Kimathi Street service desk, and pay-on-arrival delivery to all 47 counties. You pay nothing until the microphone is in your hands. The BOYA BY-DM200, its Lightning sibling for iPhone and iPad, sells at the same KSh 6,000, while the BOYA BY-MM1 costs KSh 500 less at KSh 5,500.
How does the BOYA BY-DM100 compare with the BOYA BY-MM1?
The BOYA BY-DM100 plugs directly into a USB-C port and records in stereo, while the BOYA BY-MM1 is a cardioid mic that connects through a 3.5 mm cable. The BOYA BY-DM100 handles digital conversion itself and needs no cable, so setup takes seconds. The BOYA BY-MM1 ships with a shock mount, fur windshield and two cables, and also works on cameras and PCs, though phones without a headphone jack need an adapter for it. Pick the BOYA BY-DM100 for quick phone recording and the BOYA BY-MM1 if you also shoot on a camera.
Will the BOYA BY-DM100 work with my Android phone?
The BOYA BY-DM100 is designed for Android phones and other devices with a USB-C port, and it draws its power from the phone itself. Most current Samsung, Tecno, Infinix, Oppo and Redmi models sold in Kenya use USB-C, but each brand handles external microphones in its own way, and some camera apps keep using the built-in mic. The safest step is to bring your phone to our Kimathi Street store and test it before paying, or send us your exact model on WhatsApp first.
Does the BOYA BY-DM100 cope with dust, heat and KPLC power cuts?
The BOYA BY-DM100 has no battery of its own, so a KPLC power cut never leaves you with a flat microphone; it runs as long as your phone has charge. Keep a power bank in your bag for long shoots, because the microphone occupies the charging port while you record. Like any condenser microphone, its capsules are sensitive to dust and moisture, so store it in the included pouch on dusty roads or during the long rains. Avoid leaving it on a hot car dashboard in Mombasa.
Who should buy the BOYA BY-DM100, and who should skip it?
The BOYA BY-DM100 suits Android owners who record interviews, lectures, voice-overs or short videos and want cleaner sound with almost no setup. Journalists, YouTubers, church media teams and NGO field staff get the most from it. Skip it if you own a Lightning iPhone or iPad, where the BOYA BY-DM200 is the correct fit. Skip it too if you need to record a speaker several metres away, where a clip-on lavalier or the BOYA BY-MM1 on a cable serves better.
Is the BOYA BY-DM100 good for journalists recording interviews?
The BOYA BY-DM100 is a sound choice for journalists who record face-to-face interviews on an Android phone. Its two capsules sit in an X/Y arrangement, which captures both voices in a natural stereo image when the phone rests on a table between you. The 80 dB signal-to-noise ratio keeps background hiss low, so quotes stay clear when you transcribe later. Reporters covering county assemblies or hearings at Milimani can work without a separate recorder in their bag.
What does 24-bit, 96 kHz recording mean on the BOYA BY-DM100?
The BOYA BY-DM100 converts sound to digital at 24-bit depth and a 96 kHz sample rate, above the 16-bit, 44.1 kHz standard used for music CDs. In practice, the extra depth gives you more headroom before loud voices distort and more detail in quiet passages. Whether you keep that quality depends on your recording app, since many phone apps save at lower settings. A voice recorder app that lets you choose the file format will get the most from it.
Can I use the BOYA BY-DM100 for TikTok, YouTube and Zoom?
The BOYA BY-DM100 works with apps that accept an external USB-C microphone, which includes many recording, video-calling and live-streaming apps on recent Android phones. Content creators in Nairobi use it for TikTok voice-overs, YouTube tutorials and Google Meet calls. Some phone camera apps record from the built-in mic regardless, so test your favourite app before a paid shoot. Our staff at Mascom International will plug it into your phone at the counter so you can check each app.
Technical Specifications
Core Function and Sound Pickup
- Plug-in design that connects straight to a USB-C port — no cable, clip or stand needed for phone recording.
- Two built-in condenser capsules — condenser means a sensitive element that picks up speech detail better than a phone's own mic.
- X/Y stereo arrangement — the two capsules cross at an angle, giving left and right channels for a natural sense of space.
- Cardioid pickup pattern — it hears mostly what sits in front and rejects much of the sound coming from behind.
- Powered by the phone — the BOYA BY-DM100 needs no battery, so it is ready whenever your phone has charge.
- Built for voice — interviews, lectures, voice notes, podcasts and video narration are its everyday jobs.
Audio Quality and Conversion
- 24-bit, 96 kHz converter — the microphone turns sound into digital data itself, before the signal reaches the phone.
- Multibit delta-sigma AD conversion — AD means analogue to digital; this method keeps the recorded signal clean and low in noise.
- 80 dB signal-to-noise ratio — the voice sits well above the microphone's own hiss, so quiet speakers stay audible.
- Sensitivity of -38 dB plus or minus 3 dB — a measure of how strongly it responds to sound, suited to speech at close range.
- Digital path from capsule to phone — no analogue cable run, so there is less chance of hum or interference.
- Recording format depends on your app — choose a voice recorder that saves at high quality to keep the full detail.
Compatibility and Device Support
- USB-C output — fits Android phones and tablets that charge through a USB-C port.
- Designed for Android — BOYA lists Android phones and other USB-C devices as the intended match for this model, drawing power from the host.
- App support varies by phone brand — some camera apps stay on the built-in mic, so test before an important shoot.
- Occupies the charging port — the phone cannot charge through USB-C while recording, so start long sessions with a full battery.
- Lightning iPhones and iPads need a different model — their owners should choose the BOYA BY-DM200 instead.
- Tablets with USB-C work too — handy for recording lessons, meetings or church services on a larger screen you can monitor easily.
Build and Handling
- Compact 67 x 38 x 38 mm body — fits a shirt pocket, pencil case or the corner of a camera bag.
- Plugs in at the base of the phone — keeps the camera lenses and screen clear for filming and monitoring.
- No cable between microphone and phone — nothing to tangle, snag or lose while you move between locations.
- Phone-powered design with no battery compartment — fewer parts to wear out or corrode over time.
- Pouch storage between shoots — keeps the capsules away from dust, keys and coins in a bag.
- Rides on the phone during handheld filming — keep a firm grip so the plug is never levered sideways in the port.
Inclusions and Setup
- BOYA BY-DM100 microphone — the main unit, ready to plug in out of the box.
- Carry pouch — soft storage for daily transport between home, campus and the field.
- No separate charger or battery — the microphone runs entirely on the phone's power.
- No cable to replace — the USB-C plug is part of the microphone body.
- Setup in seconds — plug in, open your recording app and confirm it is using the external input.
- Test recording advised — record ten seconds and play it back on headphones before every interview or paid shoot.
Package Contents
The BOYA BY-DM100 box contains the microphone and a soft carry pouch, which covers what most phone recording needs.

If you would like a power bank for long recording days, ask our team at Mascom International which models we have in stock.

The BOYA BY-DM100 comes with a 6-month warranty through Mascom International, covering manufacturing defects under normal use. Claims are handled at our Nairobi CBD service desk in the Old Mutual Building on Kimathi Street; bring the microphone and your receipt so our team can assess it.
