The JYX Dual UHF Wireless Microphones (model U30 on the Amazon.in listing) are a two-mic karaoke and speech set: two handheld dynamic microphones plus a small rechargeable receiver that plugs into the microphone input of a speaker, amplifier or mixer. If you want a simple cordless pair for house parties, duets, small functions or classroom announcements, it is a reasonable fit on paper, as long as your speaker has a proper MIC input and you accept that almost every spec comes from the seller’s own listing.
Our short verdict: the JYX set looks practical for casual karaoke and small events because it is rechargeable, pairs automatically and includes two mics in different colours. It is not a stage-grade system. There are no XLR outputs, no published UHF frequency band, and no independent review we could find to confirm its range, battery life or sound.
Note: this article is based on the Amazon.in listing data for ASIN B0F7XFP9ZF (captured 17 October 2026) and general microphone buying knowledge. We have not tested the JYX U30 hands-on, and we could not open an official JYX product page, so every specification below is the listing’s claim.
Quick verdict
- Best for: home karaoke, duets, birthday and wedding functions, small meetings and speeches through a speaker that has a MIC input
- Skip if: you need XLR outputs for a mixer, a documented frequency band or a brand with an official India service page
- Key strengths (as listed): two handheld dynamic mics, rechargeable mics and receiver with a 2200mAh battery in each, automatic pairing and frequency search, claimed 160 ft range, 6.35mm plug with a 3.5mm adapter
- Key limitations: must go into a MIC input (not AUX or Line in), only two charging cables for three devices, specs are seller-provided with a few inconsistencies, no independent test data

The exact product linked here is the two-microphone set with the rechargeable receiver. Check the current price of the JYX Dual UHF Wireless Microphones on Amazon.in, and confirm on the listing that you are looking at the dual set before ordering.
What you actually get in the box
According to the Amazon.in listing, the set includes two wireless microphones, one UHF receiver, one 3.5mm adapter, two USB charging cables, two anti-roll rings and a user manual. The listing title mentions “6.35mm and 3.5mm adapters”, while the box contents line lists a single adapter, so treat it as one 6.35mm-to-3.5mm converter unless the seller says otherwise.
Note that there are three rechargeable devices but only two cables, so keep a spare USB cable. The listing shows no carry case, mic covers or wall adapter, so use a phone charger you already own.
The two mics come in grey and vermilion according to the listing, which helps two singers tell their mics apart at a sangeet or karaoke night.
How the UHF wireless system works
The listing says the receiver searches automatically for the cleanest frequency for each microphone and that the mics pair with the receiver about one second after both are switched on. The listing describes no manual channel menu and no companion app.
UHF wireless mics generally use bands away from the crowded 2.4 GHz range used by Wi-Fi routers and Bluetooth speakers, which is one reason party mic sets often prefer UHF. However, the JYX listing does not state which UHF frequencies the U30 uses. If you plan to run it alongside other wireless mic systems at a venue, ask the seller for the frequency band and channel details first, because two systems on clashing frequencies can interfere.
Sound: what the listed specs mean in practice
The JYX mics are described as dynamic and unidirectional. A dynamic, directional handheld mic mostly picks up the voice directly in front of it and is less sensitive to sound coming from the sides and back. That makes it a sensible choice for karaoke, where the speaker is in the same room and feedback (the loud howl you hear when a mic picks up its own speaker) is a constant risk.
The listed frequency range of 70 Hz to 15 kHz is narrower than full audio range, but it comfortably covers the human voice, which is what a karaoke mic is for. The listed 80 dB signal-to-noise ratio is a moderate figure; a higher number means less background hiss relative to your voice. The listing also mentions “noise reduction” as a special feature without explaining how it works, so do not expect it to remove crowd noise the way a phone’s call processing might.
We found no independent measurements or published reviews of the U30’s sound, and real-world clarity will depend heavily on your speaker and room.
Connecting the JYX receiver correctly
This is the single most important point on the listing. The listing states that the receiver must be plugged into a MIC input, not “Audio in”, “Line in” or “AUX in”, otherwise no sound will be heard. Many Indian party speakers have both a mic socket (usually a 6.35mm jack, sometimes labelled MIC 1 or MIC 2) and a separate AUX input. Check your speaker’s rear or top panel before ordering.
- Karaoke trolley speakers and PA speakers: usually have a 6.35mm mic socket, so the receiver plugs in directly
- Amplifiers and mixers: use a 6.35mm mic or instrument channel, not a line-level channel
- Small Bluetooth speakers: many have no mic input at all, so this set will not work with them
- Desktop PCs: the listing title mentions PC use via the 3.5mm adapter, so use the pink mic-in jack where available
- Laptops with one combo jack: many use a 4-pole headset jack, which may not recognise a plain mic plug without a headset splitter
The listing does not mention phones, so do not assume smartphone recording works.
Battery life and charging
According to the listing, each microphone and the receiver has a built-in 2200mAh lithium battery, rated for 8 to 10 hours of use after a full charge that takes about 3 hours. For a single evening of karaoke or a function that is ample on paper. Built-in batteries also mean no AA cells to buy.
Charge all three devices the day before an event (the receiver needs charge too), and top them up occasionally if the set sits unused for months, since lithium batteries dislike being stored completely flat.
Range: what 160 ft means indoors
The listing claims a 160 ft transmission distance, roughly 49 metres. Claimed figures for wireless mics are typically measured in open space with a clear line of sight. Walls, crowds, metal structures and other wireless equipment all shorten real-world range. Keep the receiver in view of the performers rather than hidden behind a speaker cabinet.
Who should buy the JYX dual mic set
- Families who want two cordless mics for karaoke on a speaker that already has a mic socket
- Event hosts and teachers who need a quick, rechargeable pair for announcements and short speeches
Who should skip it
- Musicians or DJs who need XLR outputs into a mixer, which the listing does not mention
- Buyers who want an official spec sheet, a documented frequency band and a clearly listed India service network
- Owners of Bluetooth-only speakers without a MIC input
Alternatives worth comparing
These details come from each product’s own Amazon.in listing (captured 17 October 2026), so they are seller claims too.
- Hayden HY-58 (single mic): a one-mic UHF set with a Type-C rechargeable receiver, a 6.35mm jack and a 30 to 50 metre range in the listing title, with about 6 hours of use per charge, and the listing says it is not directly compatible with phones or computers
- Audio Array AM-W14: a dual UHF set with metal mics, two XLR outputs plus a 6.35mm mix output and a claimed 200 ft (60 m) range, but its receiver needs a power adapter and the mics need AA batteries, which are not included
- DIGIMORE D-340: a single UHF mic with a claimed 200 ft range, about 10 hours per 2-hour charge via Type-C, a 6.35mm connector with 3.5mm adapter and a 1-year warranty stated on the listing
- JBL PartyBox Wireless Mic: a set of two 2.4 GHz digital mics with a small dongle that has a 6.3mm terminal and a stated effective distance of up to 30 m, aimed at JBL PartyBox speakers
Buying tips before you order
- Confirm the variant: the linked ASIN is the dual-mic set with rechargeable receiver, so make sure the listing still shows two microphones
- Check your speaker’s MIC input: look for a 6.35mm mic socket, because AUX or Line in will not work according to the seller
- Plan for charging: keep a third USB cable and a phone charger handy
- Ask about frequencies: if you will use it next to other wireless mics, request the UHF band and channel details
- Warranty and service: the listing states a 1-year warranty, so keep the invoice and ask the seller how claims are handled in India
- Inspect on delivery: check both mics, the receiver, the adapter, two cables and two anti-roll rings are present
We also noticed small inconsistencies in the listing’s technical table: it shows “Number of Channels: 1” and the colour as “Gray”, even though it describes two mics in grey and vermilion. Check the listing images and seller answers if anything is unclear. When you are ready, see the JYX dual UHF wireless mic set on Amazon.in.
Frequently asked questions

The Amazon.in listing claims 8 to 10 hours per full charge, with about 3 hours to charge. Each mic and the receiver has a 2200mAh battery. We found no independent battery test to confirm this.
Does it need AA batteries?
No. The listing says the mics and receiver use built-in rechargeable lithium batteries and that two USB charging cables are included.
What warranty does the JYX set have?
The Amazon.in listing states a 1-year warranty. Ask the seller how and where warranty claims are processed before buying.
Final word
The JYX U30 dual set makes sense for casual karaoke and small functions if your speaker has a proper MIC input and you are comfortable buying on the strength of seller specs.
