The Digitek DWM 120 is a budget 2.4G wireless clip-on microphone system for iPhone and Android smartphones, with a claimed 50 m range, about 4.5 hours per transmitter and a charging case. It makes sense for beginners recording talking-head videos, online classes and simple interviews on a phone. The honest verdict: it is a straightforward plug-and-play phone kit backed by an Indian brand’s 12-month warranty, but its published audio range stops at 10 kHz, battery life per charge is modest, and the Amazon.in listing data has some confusing fields you should double-check.
This article is based on Digitek’s official DWM 120 product page and the Amazon.in listing (ASIN B00BJFB7CA) titled “Digitek DWM 120 Wireless Microphone System, 2.4GHz Mic, Noise Reduction, 50m Range, 4.5Hr Battery”, both checked on 17 October 2026. It is not based on hands-on testing, and we did not find an independent review, so sound quality is discussed only in terms of the published specifications.
The short version
- Worth considering if: you record on a smartphone, want no-app plug-and-play pairing and prefer a brand with an Indian toll-free helpline
- Not ideal if: you need a DSLR or mirrorless workflow, long single-charge sessions, or full-range audio for music
- What works in its favour: 50 m claimed range, noise reduction chip, charging case that refills the transmitters about twice, 12-month warranty
- What holds it back: 100 Hz-10 kHz frequency response, 58 dB signal-to-noise ratio, about 4.5 hours per charge, box contents and connector set not clearly listed

First, sort out the listing confusion
Before getting into what the specs mean, a word of caution. Some fields in the Amazon.in technical details do not match a small clip-on wireless system. The listing’s model name field says “DWM – P”, the form factor field says “Handheld”, the item weight is given as 400 g, the battery field mentions a 12V battery, and the box contents field simply says “Microphone”. None of these line up with Digitek’s own description of a lavalier-style kit with 80 mAh transmitters and a charging case, so we have not relied on them.
Two practical questions remain open. First, the number of transmitters: Digitek’s charging case specification refers to charging “2TX”, which points to two transmitters, but neither page lists the box contents in full. Second, the connectors: the official page says the kit works “whether you’re using a Lightning or Type-C port”, while the Amazon connector field lists only USB Type-C. Before ordering, check the listing photos for the number of transmitters and for a Lightning receiver or adapter if you use an older iPhone.
What the audio specs mean in practice
Frequency response of 100 Hz to 10 kHz
Human speech intelligibility sits mostly in the middle of the audible range, so a 100 Hz to 10 kHz response can carry a clear spoken voice. What you lose is the very top end above 10 kHz, the “air” and crispness in consonants, and the deepest bass below 100 Hz. For tutorials, reels and video calls this is usually acceptable. For singing, instrument recording or a podcast where you want a rich, full voice, a mic system with a wider published response, such as DJI’s 20 Hz to 20 kHz figure for the Mic Mini, is a better match.
Signal-to-noise ratio of 58 dB
SNR describes how far the voice signal sits above the system’s own electronic hiss. A higher figure is better. At 58 dB, the DWM 120 is fine for close-miked speech in normal rooms, which is how a clip-on mic is typically used, but quiet, soft-spoken recordings may reveal some background hiss once you raise the volume in editing. Clipping the mic close to the mouth, about a hand’s width below the chin, helps keep the voice well above that noise.
Noise reduction chip
Digitek says a built-in intelligent chip filters background noise. No decibel figure or on/off control is described on the official page, so we cannot say how strong it is. In general, this kind of processing helps with steady sounds such as fans, coolers and AC hum, and helps less with sudden noises such as horns or people talking nearby.
Battery and charging: plan your shoot around 4.5 hours
Each transmitter has an 80 mAh battery rated for about 4.5 hours of continuous recording and about 1.1 hours to recharge. The 500 mAh charging case, charged over Type-C in about 1.5 hours with a 5V/1A adapter, can refill the transmitters about twice according to Digitek.
Our own arithmetic from those figures: one full charge plus two refills gives roughly 13.5 hours of transmitter use across a day, but only if you pause to put them back in the case. That is enough for a few hours of classes or a half-day shoot. For a full wedding or event day, you will need charging breaks. The official page does not give a separate receiver battery figure.
Pairing and compatibility
Digitek describes the DWM 120 as plug and play with auto pairing: no app and no Bluetooth pairing are needed, and transmission is described as low latency and real time. In practice this means you plug the receiver into the phone, switch the transmitter on, and it should connect on its own, which is ideal for first-time users.
Compatibility is stated as iOS and Android smartphones. The official page does not mention DSLR, mirrorless camera or laptop use. The Amazon listing’s compatibility field does mention cameras, but since the manufacturer’s page does not, we would not buy this kit for a camera-first setup. If you need camera use, Digitek’s own DWM 121 is described as supporting DSLRs.
Android and iPhone tips
- Some Android phones need the OTG setting enabled before they detect a USB-C audio accessory
- Some Android camera apps keep using the built-in mic, so test with your phone’s default camera and with apps like Instagram or YouTube before an important shoot
- USB-C iPhones (iPhone 15 and later) need the Type-C connector, while older iPhones need Lightning, so match the receiver to your phone
Who should buy it, and who should skip it
The DWM 120 fits students recording assignments, teachers running online classes, small sellers making product reels, and anyone who wants a no-fuss wireless mic for phone videos. It also suits buyers who value an Indian support channel: the Amazon listing names IMS Mercantiles Pvt. Ltd., Delhi, with toll-free helpline 1800-123-544-444 and email support@digitek.net.in.
Skip it if you shoot mostly on a camera, sing or record music, need more than about 4.5 hours per charge without breaks, or want verified box contents before you order.
Alternatives worth comparing
- Digitek DWM 121: Digitek’s site lists TF card support, Type-C and Lightning connectors, an 80 m range, 4.5 hours of run time, and use with smartphones and DSLRs, which suits camera users and anyone who wants a recorded backup
- Digitek DWM 103 Mini: listed by Digitek with 2.4G wireless, a 50 m range, 6 hours of battery and noise reduction for iOS and Android phones and tablets, if longer battery per charge matters
- DJI Mic Mini (2 TX + 1 RX + charging case): DJI lists about 10 g transmitters, about 11.5 hours per transmitter, 400 m range in open conditions, a 20 Hz-20 kHz response and a 3.5mm camera cable in the box
- GRENARO 3 in 1 Port Version: GRENARO lists two lapel mics, a receiver for Lightning, USB-C and 3.5mm, an LED display and about 10 hours per mic, with no charging case in the listed box contents

Checklist before you order
- Confirm the listing title reads “Digitek DWM 120” and check the photos for the number of transmitters
- Check that the connector matches your phone: Type-C for Android and iPhone 15 or later, Lightning for older iPhones
- Look for the charging case in the listing images, since the box contents field does not mention it
- Keep the invoice: Digitek’s warranty is 12 months for manufacturing defects only and excludes physical damage, liquid damage and unauthorised repairs
- Record a short test clip on the day it arrives so any fault is caught within the return window
When you have confirmed the details, see the Digitek DWM 120 on Amazon.in for the current price and seller.
Frequently asked questions
Does the Digitek DWM 120 need an app or Bluetooth?
No. Digitek describes it as plug and play with automatic pairing, so no app or Bluetooth setup is required.
How many hours does the battery last?
About 4.5 hours of continuous recording per transmitter charge, with the 500 mAh case able to recharge the transmitters about twice.
Can I use the DWM 120 with a DSLR camera?
Digitek’s official page lists only iOS and Android smartphones. Camera support is not stated there, so consider the DWM 121 or a kit with a 3.5mm output if you shoot on a camera.
Does it work with the iPhone 15 and 16?
Those iPhones use USB-C, so they need the Type-C connection. Digitek says the kit works with both Lightning and Type-C ports, but confirm which connectors are in the box before buying.
What does the warranty cover?
Digitek’s page lists a 12-month warranty for manufacturing defects. Physical damage, liquid damage and unauthorised repairs are excluded, and a valid invoice is required.
Final word
The Digitek DWM 120 is a simple, phone-first wireless mic kit: plug it in, clip it on, and record. Its published specs point to voice-focused audio rather than full-range sound, and its 4.5-hour battery means planning charging breaks. Because some Amazon listing fields are inconsistent, confirm the connectors and transmitter count from the listing photos first. Check the current price of the Digitek DWM 120 on Amazon.in.
