What makes the HT420 different from wired mics for live use?

The HT420 eliminates cables on stage, giving performers freedom of movement and eliminating trip hazards during gigging and touring. It delivers the same professional cardioid rejection and dynamic character as a wired stage mic, but with wireless convenience.

How long does the battery last?

The HT420 runs six to eight hours on a single AA battery. A red battery status indicator alerts you before the battery dies, so you can plan a swap during a set break or between performances.

Can I adjust volume while I'm performing?

Yes. The transmitter has a gain control built into the mic body, so you can dial in the input level on the fly without reaching for external equipment.

Is this mic feedback-resistant for live sound?

The cardioid polar pattern and dynamic capsule design are specifically engineered to maximize gain before feedback, making it ideal for loud venues and high-SPL environments.

What's included in the box?

The package includes the HT420 transmitter with the D5 dynamic capsule. An optional CU400 charging dock accessory is available separately for convenient recharging.

Do I pay sales tax on this order?

Sales tax is collected only on orders shipped to California; orders shipped to any other US state are not charged sales tax at checkout when you buy direct from our website. Marketplaces collect sales tax as the facilitator in most states, so the same listed price can cost more there. Buyers remain responsible for any use tax their state applies. Free US shipping and 30-day returns are included.
