The String Swing Wireless Microphone is a two-mic clip-on (lavalier) kit for smartphones, sold on Amazon.in with a USB Type-C receiver, a Type-C to Lightning adaptor for older iPhones and a charging case. According to the listing, it offers AI noise cancelling, 360-degree pickup, up to 30 hours of combined battery life with the case and a 98 ft wireless range. It is aimed at phone-based creators, interviewers, teachers and small businesses.
Short verdict: the feature list covers what most phone creators want from a budget two-mic kit, especially the charging case and the Lightning adaptor in the box. The catch is that every spec comes from the seller’s listing. We could not find an official String Swing product page for this String Swing Wireless Microphone, and no independent reviews were found, so treat the numbers as claims and test the mic within the return window.
This article is based on the Amazon.in listing checked on 17 October 2026, plus general buyer guidance for phone wireless mics. It is not a hands-on review and makes no claims about how the String Swing Wireless Microphone actually sounds.

About the brand: what we could and could not verify
The Amazon.in listing shows the brand as “String Swing” and the model number simply as “LM”, which reads like a generic code rather than a named model. We looked for an official product page and did not find one. The website at stringswing.com belongs to a Wisconsin-based maker of guitar hangers and racks, and it lists no microphones, so do not assume any link between that company and this product.
This matters for two reasons. First, there is no second source to confirm the listing’s specs. Second, warranty service will most likely run through the seller, so read the seller details on the listing and keep your invoice. The listing states a 1-year warranty, but it does not say how claims are handled.
What you get in the box
According to the listing, the box contains two wireless microphone transmitters, one Type-C receiver, one Type-C to Lightning adaptor for iOS, one charging case and one charging cable. That is a generous bundle for a phone kit. The charging case is the main convenience: you drop the mics back in after a shoot and they recharge from the case’s own battery, which is how the listing reaches its 30-hour combined figure.
The listing does not mention a windscreen (the small foam or fur cover that cuts wind noise outdoors) or a 3.5 mm cable for cameras. If you record outside often, a pair of clip-on windscreens is an inexpensive add-on worth considering.
The 30-hour battery claim, explained
Combined battery figures can be misleading. “30 hours combined” usually means the hours each transmitter runs on a single charge plus the extra recharges the case can provide. It does not mean one mic will run for 30 hours straight. The listing does not give the per-mic runtime, the case capacity, or the charging time, so you cannot tell how long a single uninterrupted recording session can last.
For most short-form content this will not be a problem, because you can top up the mics in the case between takes. For long events, such as a two-hour seminar or a wedding speech recording, ask the seller for the per-mic runtime before relying on it. The battery indicator light listed among the features should at least show when a mic is running low.
Range, pickup and AI noise cancelling
The listing claims a stable connection up to 98 ft (about 30 m). As with all wireless mics, that is a best-case, line-of-sight figure. Bodies, walls and pockets reduce it, so keep the String Swing Wireless Microphone phone within view of the speakers for important recordings.
The 360-degree omnidirectional pickup is normal for lavalier mics, since the capsule does not need to point at the mouth. It also means the String Swing Wireless Microphone hears the room, which is where the AI noise cancelling comes in. The listing does not say whether it can be switched off. That detail is worth checking, because noise processing that helps on a busy road can make a voice sound thin or processed in a quiet room. The listing also mentions echo control, but does not explain what it does.
The listing’s 80 dB signal-to-noise ratio would be a good figure for a budget phone mic, but with no measurement method stated and no independent test available, treat it as a claim rather than a guarantee of low hiss.
Two mics, one receiver: how recording works
With two transmitters and one receiver, you can mic up two people at once, which is the main reason to buy a dual kit. The listing says “2” channels, but it does not say whether the two voices are recorded as separate left and right channels or mixed into one track. Many phone video apps record a single mixed track anyway, so for typical Reels, YouTube interviews and vlogs this rarely matters. If you plan to edit each speaker’s volume separately in post-production, confirm the channel behaviour with the seller.
iPhone and Android compatibility
The String Swing Wireless Microphone uses USB Type-C, which fits Android phones with a USB-C port and iPhone 15 and later models. For older iPhones with a Lightning port, the listing includes a Type-C to Lightning adaptor. The listing describes the setup as plug and play, with no pairing or app required.
Two cautions apply. Some phones and some third-party camera apps handle external USB mics differently, so test with the app you actually use, such as Instagram, YouTube or your phone’s camera app. And since the String Swing Wireless Microphone occupies the charging port, you may not be able to charge the phone while recording, as the listing does not mention pass-through charging.
Who should buy it, and who should skip it
Consider it if you shoot on a phone, often record two people, and value the convenience of a charging case. It suits interview-style Reels, couple and family vlogs, small podcasts recorded on a phone, and online classes.
Skip it if you shoot on a camera with a 3.5 mm mic input, since no camera cable or output is listed. Also skip it if you want verified specs, a known brand with an official support channel, or a mic that has been independently reviewed. Solo creators who only need one mic can keep things simpler with a single-mic kit, or even a wired lavalier like the one in our BOYA BY-M1 review.

Before you order
- Confirm the listing: the link here is for the String Swing Wireless Microphone with two transmitters, a Type-C receiver, a Lightning adaptor and a charging case. Check that the title and box contents match before you pay
- Check your phone port: USB-C phones use the receiver directly, and Lightning iPhones need the included adaptor
- Ask about per-mic battery life if you record long sessions
- Check seller and warranty details: the listing states a 1-year warranty, but no official brand support page was found, so keep your invoice and note the seller name
- Test early: record a test clip with both mics in your usual location within the return window, with noise cancelling on and off if that option exists
If the box contents and seller terms suit you, see the String Swing two-mic kit on Amazon.in.
Setup and care tips
Charge the case and both mics fully before the first use. Plug the receiver into the phone, switch on the transmitters, and check that the indicator lights show a connection. Clip each mic on the chest about a hand’s width below the chin, away from collars, jewellery and hair that can rub against it. Record a ten-second test and play it back on headphones before the real take. Afterwards, return the mics to the case so they charge and do not get lost, and keep the Lightning adaptor attached to the case or receiver so it does not go missing.
