The GSM Spy Bug LONGLIFE 20+ presents with distinctly clear audio due to an extended high-quality microphone, and a battery life of up to 20 days in standby mode. 

The Plus (+) in the name of the device and the main difference from the LONGLIFE 20 model is the longer microphone cable, so you can set the environment up to perfectly cover your audio recording needs. 

The LONGLIFE 20+, from the StealthTronic LONGLIFE series, is a remarkable GSM Bug featuring a 6x longer battery life than standard GSM Bugs. With its small size, clear audio, long-lasting battery life, and extended microphone it is a fitting device for easy concealment in spaces in which you can't use power sockets. 

The LONGLIFE 20+ provides 8-10 hours of continuous listening time and 2-3 days in voice-activated mode. The setup of the device is very easy. When the device is charged, you insert a SIM Card and call upon the device. After that, you can call the device and listen to everything in its near vicinity, and the voice activation can be remotely powered on/off via SMS.

If you are looking for smaller and lighter GSM Bugs with shorter standby and listening times, take a look at the LONGLIFE 10 featuring up to 10 days of standby and 4-6 hours of listening time along with the Micro GSM Spy Bug, the smallest and lightest device from the LONGLIFE series, featuring up to 3 days in standby and 1.5 hours of listening time. 

As similar options, the LONGLIFE 20 and LONGLIFE 20 PRO K+ feature the same specifications, however, while LONGLIFE 20 offers an integrated microphone, LONGLIFE 20 PRO K+ offers a longer extended microphone and the high-quality Knowles microphone. 

If you need more standby and listening time, the LONGLIFE 60 provides 75 days of standby and 26 hours of listening.
