The GTD Audio G-380H is a popular system due to its very low price. The price is kept down in 2 main ways - the system is not expandable and will cause interference if you try using 2 systems at the same time, and the microphones are only basic ones.

The volume of each of the 4 mics can be set independently at the receiver and a mixed signal taken out, or you can simply take all 4 balanced XLR lines out independently to your mixing console.

Although the majority of user reviews are quite favorable, some do mention quality control issues and a few report that one or more of their mics stopped working in less than a year.

Most of the reports about range were positive with only a few users reporting interference or noise issues.

Feature Overview

• Mic frequency response: 45Hz to 18KHz
• Receiver frequency: 240 - 260 MHz
• Range: 350 feet
• Individual Balanced XLR and a mixed non-balanced 1/4" output
• Battery Life: 9 Hours

Overall this is an okay system given the low price, however you must handle with care and don't expect the same year in and year out robust performance you would expect from a more expensive system.

GTD Audio gets good ratings, not because they're the highest quality, but because they offer good value for money and those who are budget conscious rate this double mic package very highly.

One of the most common positive comments about the GTD Audio 622H system is that the mics, although enclosed in solid plastic rather than metal, have a good weight and feel to them.

The most commonly reported negative is that the second mic has problems with dropouts after a while, although the manufacturer will replace them under warranty.

Feature Overview

• Mic frequency response: 45Hz to 18kHz
• Receiver frequency: UHF 550MHz - 580MHz
• Range: Up to 450 feet / 150 meters
• Two XLR individual outputs and one 1/4" TRS Mixed output
• 100 selectable frequencies on each channel
• Individual volume control on each channel
• Rack mountable in a standard 19" rack

Most users are satisfied with the overall quality and performance of the GT Audio G-622H, especially when considering the price. Mobile DJs and event singers were happy with the sound quality as were those using it in fixed installations such as houses of worship.

This is very much an entry-level system, and some report moving up to more expensive options after using it for some time, still it's hard to beat the extremely low price.

This system uses the Sennheiser e835 dynamic microphone capsule which has good ratings as a live vocal mic and competes in the same class as the Shure SM58.

It features 12 channels which can be selected automatically or manually and you can use multiple units on stage at the same time.

One handy feature is that the on/off switch is positioned at the bottom of the mic so signers don't end up turning it off accidentally during performance.

Feature Overview

• Mic frequency response: 50Hz to 16kHz
• Receiver frequency: 548MHz to 572MHz
• Range: Up to 250 feet
• Balanced XLR and non-balanced 1/4" output
• 12 Channels: Both manual and automatic selection available
• Table Top form factor

This wireless system is a good alternative to the Shure BLX24R/SM58 for those of you who prefer the Sennheiser e835 over the SM58.

The Sennheiser EW 165 G3's distinction is its use of a condenser mic capsule, which allows for a wider frequency response than conventional dynamic microphones. This wider frequency response allows for more sonic nuances and improved clarity, which many vocalists prefer.

Combining this highly sensitive mic with a reliable wireless system makes for a great mic that captured the hearts of many of its users. It features a fully programmable receiver, with twenty frequency banks and 12 preset frequencies each, allowing for quick setups. There's also a special sound check mode that lets you check the RF signal and audio discretely.

Feature Overview

• Mic frequency response: 80Hz-18kHz
• Receiver frequency: UHF 516MHz - 558MHz
• Range: Not Specified
• One XLR output and one 1/4" TRS Mixed output
• Transmitter Battery: 2 x AA (Up to 8 Hours) or Sennheiser BA 2015 Accupack
• IR sync function with Up to 8 Systems running per channel
• Rack mountable via optional mounting kit

Many were very happy with the Sennheiser EW 165 G3's overall performance, but most of the praises came from singers and vocalists who felt that they sounded and performed better with this mic. Ease of use and reliability were also pointed out along with its solid construction. There was one person who had some bones to pick with the included mic clip being too tight, but most are impressed with its overall performance. If you're looking for a high quality wireless condenser microphone then the Sennheiser EW 165 G3 is a worthy investment.
