Very affordable and very good.

The Audio-Technica ATW-251 Freeway VHF Headworn Wireless System is designed to provide reliable performance, easy setup and clear, natural sound quality. The Freeway Wireless Microphone System includes the ATW-R250 receiver, the ATW-T201 body-pack transmitter, and the PRO 8HEcW hands free microphone. A novel dipole antenna system on the receiver improves operation by providing a ground element in addition to the usual signal element.

ATW-R250 receiver

The ATW-R250 receiver includes a space-saving switching power supply that automatically adapts to changes in mains voltage. Unlike bulky linear power supplies, this switching power supply is lightweight and compact; it uses only a single outlet space.

ATW-T201 UniPak body-pack transmitter

The versatile ATW-T201 UniPak body-pack transmitter has both a high-impedance input for instruments, and a low-impedance input with bias connection for use with dynamic and electret condenser microphones. The ATW-T201 uses internal 9-volt batteries and has an Off/Standby/On switch, input Trim (level) adjustment, and battery-save switch.

PRO 8HEcW headworn microphone

Offering highly intelligible individual voice reproduction, the comfortable, lightweight PRO 8HEcW headworn microphone is ideal for guitarists, keyboard players, drummers and others who need the use of their hands during performance. Its low-visibility headband and cushioned support pads provide a stable, comfortable fit. Designed for professional quality vocal pickup with hands free operation, the PRO 8HEcW features a pivot-mounted flexible mic boom that descends from either the left or right side. Terminated with a locking 4-pin connector for the Audio Technica A-T UniPak body-pack wireless transmitters. The PRO 8HEcW has a 55" (1.4 m) cable and includes a windscreen.

Comments about Audio-Technica ATW-251 Freeway VHF Headworn Wireless System:

This is my third Audio Technica Mic and I am thrilled to purchase another one. The price is right and
I put a lot of wear and tear on them! Love the reliability, sound quality and comfort of this product.

I usually have trouble with the size of headphones, but this headset fits my unusually small head.

I will continue to buy more of these in the future as long as they never discontinue the product line.
Thanks and keep up the great work.
