The GSM Spy Bug LONGLIFE 20 records clear sound due to the high-quality microphone. The bug can last up to 10 h in continuous listening mode, and up to 20 days in standby mode.

The LONGLIFE 20 is from Stronic's LONGLIFE Bug series, which has virtually no competition when it comes to battery life and continuous listening/standby time.

 

The battery lasts 6x times longer than those of standard GSM Bugs, the microphone records clear sound in a wide radius, and calling upon the device for listening purposes is simple. When the SIM card is inserted in a fully charged GSM Bug, you can call the device and start listening. 

 

Longlife 20 is perfect for spaces that do not offer a power supply, however, it can also be used indoors in warehouses, offices, etc. 

 

As a similar option with the same specifications but with an extended microphone, take a look at the LONGLIFE 20+. The extended microphone can help you better set up the Bug in your chosen environment. Another version is the LONGLIFE 20 PRO K+, which provides an even longer extended microphone that allows you to pick sound from 10+ meter distance and features the high-quality Knowles microphone for extra clear audio.

 

If you need more standby and listening time, check out the LONGLIFE 60 which comes with 75 days of standby time and 26 hours of continuous listening. 

 

On the other hand, if you need less standby and listening time or more compact GSM Bugs, take a look at the LONGLIFE 10 which provides up to 10 days of standby time and 4-6 hours of continuous listening time. The smallest in the LONGLIFE series is the Micro GSM Spy Bug, weighing only 6g and offering up to 3 days of standby time and 1.5 hours of continuous listening time.
