Advanced features. Low price.

This Nady UHF-4/HM-3 headset wireless microphone system offers high-quality wireless for an amazingly affordable price. It gives you interference-free operation on select UHF frequencies, companding circuitry for an exceptional 120dB dynamic range, and clear, natural sound. The DigiTRU Diversity dual-antenna system prevents dropouts and extends its range. The Tone Squelch function blocks potential interference while full LED indicators keep you on top of things. The UHF-4 also features unbalanced 1/4", unbalanced XLR outputs, and silent transmitter on/off.

The wireless mic system comes with a receiver, bodypack transmitter, and HM-3 mic headset. The Nady Transmitter features status and low-battery indication and an off/standby/on switch. A 9V alkaline or NiMH battery provides 4-6 hours of continuous usage.

HM-3 Headmic
With the Nady HM-3 wireless mic, DJs, speakers, aerobic instructors, auctioneers, and others who require handsfree mobility and high-quality spoken vocals with improved gain before feedback can achieve better performance than is available with small omni-directional lapel microphones. With its high sensitivity and ultra clarity, the HM-3 headset is optimally designed for all speaking applications. The close-up unidirectional vocal pickup provides a full sound while suppressing irritating background noises.

The HM-3 microphone features an adjustable boom that can be set at any angle required. The headworn support system is extremely light and comfortable, and is designed to be visually unobtrusive while worn. Its ear rests and temple provide maximum stability during use, even while moving, or shaking the head. The durable cable assembly and internal construction are designed to minimize handling noise from contact and movement.

This headset mic incorporates state-of-the-art technology in an ultra-light housing that can be worn for many hours at a time in total comfort. The advanced design offers improved reliability under adverse operating conditions and stable performance. The headband's shaped rests are placed on top of each ear and the rest of the band extends around the back of the head. The pad supporting the boom rests on the temple in front of the ear, providing the necessary stability during use. The flexible mic boom descends from the ear on the left side and can easily be adjusted for the proper angle required.

The Nady HM-3 headworn mic requires no troublesome batteries and is phantom powered from the input connector to the transmitter.

Consumer Alert:

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.

UHF-4 LT/HM-3 (115) Headset Wireless System

Fantastic sound, terrible headset/mic assy.

Mechanical issues!
There is one major problem with the headset rcv'd.

(Movement wise) -- the headset assembly is very unstable -- flips &amp; flops with no stability during head movement. The (light weight plastic boom assembly) moved back &amp; forth with a 2 to 3 inch span during normal head movement. It was very difficult to adjust, and the whole assembly would slip and slide around during use.

(Sound / audio performance wise) -- the sound was fantastic -- no audio feedback during normal operations noticed.

The headset is being replaced -- hopefully the above issues will be resolved.

I will give a rating after the headset issue is resolved.

Tks -- Jim

Comments about Nady UHF-4 LT/HM-3 (115) Headset Wireless System:

I am a guitarist who sings alot of background and some lead vocals.This is just what I need so I can sing and change effects as I look down without not worrying about a mic stand.
When I first opened it the pink cover fell off and I had to glue it back on,that's pretty crummy.The unit itself is cheesy but you get what you pay for.
Value wise this is a good unit.The headset is comfy and the mic bends to where you need it.I use recharchable cadmium batteries in it and it does not eat alot of juice as long as you turn it off between sets obviously.The volume setrtings and squelch settings are nice too.

Comments about Nady UHF-4 LT/HM-3 (115) Headset Wireless System:

I'm a guitarist and the use for this is perfect. The other reviews were way off and here's why. I've owned many of the Nady products over the years and they are designed to take reasonable abuse. I've had transmitters fall off, split open and battery fly out only to reassemble it and work flawlessly. Spend the extra $$ for the UHF model as they are interference free and known for their quietness.
I connected this to the PA, set the receiver volume to about 11 O'clock and dialed in the transmitter to just touch the red led on the receiver. Used the PA to bring up the volume. The sound is quiet of interference, loud without feedback, and is comfortable.
You could spend extra $$$ on a shure but if you are on a budget this is the one for you. You will be pleasantly surprised the sound quality. For obvious reasons this is not suitable for recording but for live performances it is the gem. If I could say anything negative it would be the screw in jack on the transmitter is subject to fail but only after many hours of solid operation. 2 thumbs up for me!

Comments about Nady UHF-4 LT/HM-3 (115) Headset Wireless System:

Quality control issues, the one I received had a broken mini plug and I had to send it back. After that they said it was out of stock and I had to wait a month to get a replacement.
