The GRENARO S11 is a budget clip-on wireless microphone kit whose 3-in-1 receiver has Lightning, USB Type-C and 3.5 mm outputs, so one receiver can work with an older iPhone, an Android phone or a camera with a mic input. It suits beginner YouTubers, teachers and interview-style creators who want their voice recorded close to the mouth instead of through the phone’s built-in mic. The short verdict: it is a flexible, simple starter kit on paper, but GRENARO publishes very few audio specifications, and the Amazon.in listing and the brand’s own product page do not agree on how many microphones you get, so check that detail before ordering.
This article is based on GRENARO’s official product page, the Amazon.in listing data and publicly available information, all checked on 17 October 2026. We have not tested the S11 hands-on, and we could not find an independent lab review of this model, so you will not find sound-quality impressions or measured battery results here.
The variant behind our link is the S11 3-in-1 version in Black, listed on Amazon.in as “GRENARO Wireless Mic for Youtubers, S11 3 in 1 Wireless Microphone for iPhone/Android/DSLR Camera/USB-C Plug/iPad”. GRENARO also sells a Type-C-only S11 on its own site, which is a different product and is not the item behind our link.
Quick verdict
- Best for: new creators who shoot on a phone today but may add a DSLR or mirrorless camera later and want one receiver for both
- Skip if: you need published audio specs (SNR, sample rate, frequency response), on-board backup recording, or a charging case
- Key strengths: one receiver with Lightning, USB-C and 3.5 mm outputs, claimed 164 ft (about 50 m) range, noise-reduction and reverb modes, 1-year warranty
- Key limitations: conflicting information on the number of transmitters, no audio performance figures on the listing, no charging case listed in the box, and no independent test data we could find

Every entry above comes from GRENARO’s product page or the Amazon.in listing, as labelled. Check the current price of the GRENARO S11 3-in-1 on Amazon.in and confirm the box contents shown on the listing.
The one-transmitter or two-transmitter question
This is the most important thing to settle before you buy. The Amazon.in listing’s box contents name one wireless microphone transmitter, one 3-in-1 receiver, a USB to Type-C cable, wind wool, a windproof sponge, clips and a user manual. GRENARO’s own S11 product page, however, describes a “dual microphone system” with two lavalier mics and a combined runtime of more than 20 hours.
The two sources may describe different packs, or one may be out of date. A one-mic kit works well for solo talking-head videos, reels and online classes. A two-mic kit is what you need for interviews, podcasts with a guest, or couple and family vlogs where both voices must be clear. Open the listing, read the box contents and look at the product images before you place the order, and if it still is not clear, ask the seller through the listing’s question section.
How the 3-in-1 receiver works in practice
Most budget wireless mic kits ship either a USB-C receiver, a Lightning receiver, or a camera receiver. The S11 3-in-1 version combines all three outputs in one receiver, according to both the listing and GRENARO’s page. Here is what each output is for:
- Lightning: iPhones up to the iPhone 14 series and older iPads that still use Apple’s Lightning port
- USB Type-C: Android phones with USB-C, the iPhone 15 series and later, and USB-C iPads
- 3.5 mm: cameras with a 3.5 mm microphone input (many Canon, Sony and Nikon bodies, per GRENARO), and computers with a mic input
GRENARO’s page also mentions automatic switching between three modes (mobile devices, amplifier and camera). In plain terms, the receiver is meant to detect what it is plugged into, so you should not need to set an output manually. We cannot confirm how reliably this works because we have not used the product and found no independent test of it.
One practical caution: a 3.5 mm camera connection needs the camera to have a microphone input jack. Many entry-level camcorders, action cameras and point-and-shoots do not have one, so check your camera’s spec sheet first.
Noise reduction and audio modes
The listing says the S11 uses a DSP (digital signal processing) chip that reduces background noise automatically, and GRENARO’s page lists four audio modes: original sound, noise reduction, reverb and mute. Each mode has a practical use:
- Original sound: best in a quiet room, because noise reduction can make a voice sound thinner or slightly processed
- Noise reduction: useful for fan noise, traffic hum or a busy cafe, where steady background sound competes with your voice
- Reverb: adds an echo effect, mostly for singing or karaoke-style clips, not usually wanted for speech
- Mute: lets you cut audio quickly, for example during a live stream
What the listing does not give is just as important. There is no signal-to-noise ratio, no sample rate or bit depth, and no audio frequency response. The listing’s “Frequency Response: 2402 MHz” entry is the radio transmission band, not the range of sound the mic captures. The listing also shows an “Audible Noise: 30 Decibels” field without explaining how it was measured, so we have not treated it as a performance figure.
Range, design and battery
Both GRENARO and the listing claim a range of up to 164 feet, which is about 50 metres. Treat this as a best-case figure, because walls, crowds and other 2.4 GHz devices such as Wi-Fi routers usually shorten real-world range.
The transmitter clips onto clothing and the kit includes both a foam windscreen and a furry “wind wool” cover. The furry cover is the one to use outdoors, because foam alone usually does little against real wind. The listing gives an item weight of 80 g and dimensions of 10.5 x 10.5 x 2 cm, which most likely describe the packaged set rather than the clip-on mic itself.
The listing says both the transmitter and the receiver need charging, and the box includes a USB to Type-C cable. GRENARO’s page claims about 10 hours per mic. The listing does not mention a charging case, so plan to charge the parts by cable before a long shoot.
Phone and app compatibility notes
Both GRENARO and the listing add two notes that are worth reading before you buy:
- On OPPO, vivo, Xiaomi, OnePlus and realme phones, the connection may fail until you search for “OTG” in Settings and turn on OTG power or connection.
- Some Android phones’ built-in camera apps do not record from an external mic. GRENARO suggests a third-party app such as Open Camera, with the external mic selected as the audio source.
Apps like Instagram, YouTube and WhatsApp handle external mics differently, so record a short test clip in the app you actually use before relying on the mic for an important shoot.
Who should buy it, and who should skip it
The GRENARO S11 3-in-1 makes sense if you want one receiver for a Lightning iPhone, a USB-C phone and a camera, you mostly record speech, and you are fine judging sound from user samples because the brand does not publish audio specs.
Skip it if you need a guaranteed two-mic kit at a glance, a charging case for top-ups on the go, internal backup recording on the transmitter, or published audio performance numbers. Professional and paid work is better served by kits with documented specifications.
Alternatives worth comparing
- GRENARO S13: GRENARO’s charging-case model with 3-level adjustable noise reduction and a claimed 30 m range, but its receiver is USB-C with a Lightning adapter and no camera output
- DJI Mic Mini: DJI lists about 11.5 hours per transmitter, a transmitter weight of about 10 g and a charging case, with a 3.5 mm TRS camera cable listed in its specifications
- Hollyland Lark M2: Hollyland lists a 9 g transmitter, 48 kHz/24-bit audio, ENC noise cancellation and separate Lightning, USB-C and camera receiver versions
- BOYA BY-M1: a wired lavalier with a 6 m cable and a 3.5 mm plug, a simpler option if you can live with a wire
We have covered the wired BOYA option in our BOYA BY-M1 review, and our YouTube starter kit guide for India explains how a mic fits alongside lights and a stand.
What to check before you order
- Read the box contents on the listing and confirm whether it ships one transmitter or two.
- Confirm the title says the S11 3-in-1 version, not a Type-C-only version, if you need Lightning or camera output.
- Check your phone’s port: Lightning, USB-C, or neither (some older Android phones use micro USB, which GRENARO does not list).
- For camera use, confirm your camera has a 3.5 mm mic input.
- Keep the invoice. The listing and GRENARO both state a 1-year warranty, and GRENARO’s page mentions a 3-day return for quality issues and replacement for transit damage reported within 24 hours.
- Test the mic as soon as it arrives, in the app you plan to use, so any problem is caught inside the return window.
If the box contents match what you need, see the GRENARO S11 3-in-1 (Black) on Amazon.in.
Frequently asked questions
Does the GRENARO S11 work with the iPhone 15, 16 or 17?
Yes, on paper. The 3-in-1 receiver has a USB Type-C output, and GRENARO’s page lists the iPhone 15, 16 and 17 among compatible devices. Older iPhones use the Lightning output.
Can I use the GRENARO S11 with a DSLR or mirrorless camera?
The 3-in-1 version has a 3.5 mm output for cameras with a microphone input, according to the listing and GRENARO’s page. Check that your camera has a 3.5 mm mic jack before you buy.
How many microphones come with the S11 3-in-1?
The Amazon.in listing’s box contents show one transmitter, while GRENARO’s product page describes a dual-mic system. Confirm on the listing before ordering.
What is the battery life of the GRENARO S11?
GRENARO’s page claims about 10 hours per mic. The Amazon.in listing does not state a battery figure, and we found no independent battery test.
Why is my Android phone not detecting the mic?
GRENARO advises turning on OTG in Settings on OPPO, vivo, Xiaomi, OnePlus and realme phones. If the stock camera app ignores the mic, try a third-party camera app such as Open Camera.
Final word
The GRENARO S11 3-in-1 stands out for one reason: a single receiver that covers Lightning, USB-C and cameras. Its weak points are thin published specs and conflicting information on the number of transmitters, so confirm the box contents first. If that checks out, check the current price of the GRENARO S11 on Amazon.in.
