Wireless Lavalier Microphone Kit

The NPTCL K1 is a two-piece wireless lavalier system designed for creators recording on iPhone 15, 16 or 17 models and Android phones. It targets vloggers, live streamers and podcasters who need hands-free capture for two speakers at once. The kit includes a charging case and windscreen covers.

35-Hour Charging Case

The single specification that decides fit is the 35-hour total runtime provided by the charging case. Each microphone runs for seven hours on a full charge and the case displays remaining battery levels numerically. If your sessions regularly exceed seven continuous hours without a recharge break, this case capacity is the limiting factor.

Sustained Recording Behaviour

During long sessions the omnidirectional capsules maintain a 68-decibel signal-to-noise ratio and -38-decibel sensitivity while the DSP chips suppress background noise. The 2200-ohm impedance remains stable and the 70-foot effective range holds without latency drift. Windscreen covers continue to block plosives throughout the full 35-hour cycle.

Questions about this item

What does 35 hours of battery life with the charging case mean for a full day of recording?

The case delivers up to 35 hours total; each microphone runs about 7 hours per charge, and the LED numbers on both the mics and case show the remaining power at a glance.

How does the 75-foot wireless range hold up in practice?

The system is rated for a maximum effective distance of 70 feet, providing steady, low-latency audio for vlogging or streaming when you need to step away from the phone.

What connectors do I need on my phone for the K1 to work?

The kit includes a USB-C receiver for modern Android handsets and iPhone 15/16/17 models, plus a Lightning receiver for earlier iPhones, so you can plug straight in without adapters.
