The Audio Array AM-W33 is a single handheld UHF wireless microphone with a plug-in rechargeable receiver, meant for karaoke, weddings, church services, DJ sets and small events where you already have a speaker, amplifier, mixer or party box with a 6.35 mm input. Its main appeal is the spec sheet: a dynamic cardioid mic with 24-bit/48 kHz audio, a 20 Hz to 20 kHz range and a claimed range of up to 50 m.
The short verdict: it looks like a sensible single-singer or single-speaker upgrade from a wired mic, but the Amazon.in listing and Audio Array’s own pages disagree on the battery, the body material, the channel count and the weight. The biggest practical question is whether the handheld mic arrives with its battery fitted, so confirm that before you order.
This article is based on Audio Array’s official AM-W33 product page and user-guide post, plus the Amazon.in listing, all checked on 17 October 2026. We have not tested it, and we did not find an independent review of the AM-W33 to cite.
At a glance
- Good for: one singer or host using a party speaker, karaoke box, amplifier or mixer with a 6.35 mm (or 3.5 mm via adapter) input
- Not for: phones, laptops or tablets, or duets and panel talks that need two mics at once
- Strengths on paper: dynamic cardioid capsule, 24-bit/48 kHz, 20 Hz to 20 kHz, signal-to-noise ratio of at least 90 dB, anti-roll rings, rechargeable receiver with Type-C charging
- Concerns: unclear battery situation for the mic, “Metal” in the title while the listing says ABS plastic, a “dual-channel” claim on a one-mic set, and no stated warranty term

The battery question you must settle first
This is where buyers can get caught out. Audio Array’s product page says the microphone needs 3.7 V 18650 batteries and that they are not included. The Amazon.in listing’s first bullet says “No standalone lithium batteries are sold with the product”, which could mean either that no battery comes in the box or simply that no loose spare cell is supplied. Yet the listing title advertises 2000 mAh and 6-8 hours of backup, and Audio Array’s user-guide post (which describes a two-mic version of the AM-W33) says the mic and receiver each use a 3.7 V 18650 800 mAh cell, with 1-2 hours to charge.
What is consistent is that the receiver has a built-in rechargeable battery and charges over a USB-A to Type-C cable. For the handheld mic, ask the seller through the Amazon.in question section, or check the latest listing photos, whether an 18650 cell is fitted. If you need to buy one, choose a reputable 3.7 V 18650 cell of the right physical size, insert it with the correct polarity, and never use a swollen or dented cell.
Also note the charging advice in Audio Array’s guide: it says the set is not compatible with Type-C to Type-C cables. Use the supplied USB-A to Type-C cable with a normal USB charger.
Sound: what the numbers mean in a hall
A dynamic cardioid mic is the classic choice for live vocals. Dynamic capsules handle loud voices without distorting, and the 130 dB maximum SPL on Audio Array’s page supports that. The cardioid pattern means the mic mainly hears what is in front of it, which helps against feedback when speakers are on stage, as long as you keep the mic pointed at your mouth and not at the speaker.
The 20 Hz to 20 kHz range and 24-bit/48 kHz figure suggest the AM-W33 is designed for singing, not just speech. A signal-to-noise ratio of at least 90 dB means the system’s own hiss should sit well below your voice. These are the manufacturer’s numbers; real results depend heavily on the speaker you plug into and on how you hold the mic.
The listing’s model name field mentions “with Effects”, but neither the listing bullets nor the official page describe any echo or reverb controls on the mic or receiver. If you want echo for karaoke, rely on your speaker or mixer’s effects rather than expecting them here.
Range and wireless band
Both sources quote up to 50 m, with a more cautious 30-50 m in the descriptions. In practice, UHF range shrinks with crowds, walls and metal stage structures, so the lower figure is the safer planning number for a wedding hall or church.
The Amazon.in technical details give the frequency range as 902-928 MHz. Audio Array’s own product page does not state the band. UHF bands are regulated differently from country to country, so it is reasonable to ask the seller which frequency the unit sold in India uses, especially if you plan to run it alongside other wireless mics.
Setting it up
- Charge the receiver with the supplied USB-A to Type-C cable before first use
- Confirm the mic has a charged 18650 cell fitted, as discussed above
- Turn the speaker or mixer volume to low
- Plug the receiver into the 6.35 mm mic input, or use the included 6.35 to 3.5 mm adapter for a 3.5 mm input
- Switch on the receiver, then the mic, and wait for them to connect
- Speak into the mic and raise the speaker volume slowly until it sounds right, backing off at the first sign of feedback
- Fit an anti-roll ring so the mic does not roll off a table
One oddity: Audio Array’s user-guide post says the system is not compatible with 3.5 mm aux inputs, yet both the listing and that same post include a 6.35 to 3.5 mm adapter. A 6.35 mm mic input is the safest match, and if your speaker only has a 3.5 mm aux input, test it promptly within the return window.
Who should buy it, and who should not
Buy the AM-W33 if you sing karaoke at home or host small functions on a party speaker or amplifier with a 6.35 mm input, and one wireless mic is enough. It also suits a church or community hall replacing a worn wired mic.
Skip it if you need two mics together (look at a dual set instead), if you want to record into a phone or computer (Audio Array’s guide says it is not compatible with smartphones, computers or tablets), or if a metal body matters to you, since the listing’s material field says ABS.
Alternatives worth comparing
- Audio Array AM-W33 Pro: a solo UHF wireless mic system with a carry case and 24-bit/48 kHz audio, according to its official product title
- Audio Array AM-W36 Pro: a UHF microphone system with anti-feedback technology and a stated 100-150 m range, per its official product title, for bigger venues
- DIGIMORE D-316: a fixed-frequency UHF system with one handheld mic and one headset lapel mic, two channels, cardioid pickup and a stated 150 ft range, per DIGIMORE’s official store, for a singer plus a host
Before you order
- Confirm the ASIN is the AM-W33 Solo set: one handheld mic and one receiver, Black
- Ask whether the 18650 battery for the mic is included and fitted
- Check that your speaker or mixer has a 6.35 mm mic input, or a 3.5 mm input you can test
- Check the box contents match the listing: receiver, adapter, two anti-roll rings, USB-A to Type-C cable and manual
- Keep the invoice and register the product on Audio Array’s warranty registration page, since no warranty term is stated on either page. Audio Array lists support@audioarray.in for help
- Test range, battery and feedback at home before the event, inside the return window
Once those details check out, see the Audio Array AM-W33 Solo UHF wireless mic set on Amazon.in.

Final thoughts
On paper, the Audio Array AM-W33 has the right ingredients for a single wireless vocal mic: a dynamic cardioid capsule, 24-bit/48 kHz audio and a rechargeable plug-in receiver. The listing’s mixed messages on battery, material and channels mean you should buy it with your eyes open and confirm the details first.
