The Micro GSM Spy Bug is the smallest and lightest device in the LONGLIFE family. Especially suitable for missions where you need something compact and efficient, with limited space to hide the Bug. 

The Micro GSM Spy Bug provides you with a high-quality microphone for clear sound and a significant battery lifetime. The Micro Bug can be up to 3 days in standby mode, provide up to 1.5 hours of continuous listening, and 10-15 hours of audio recordings in voice activation mode

The call-back function is very simple to configure, and you can remotely power it on/off via SMS. When the device is fully charged and the SIM Card is inserted, you can call upon the device and start listening to audio from the device's acoustic environment. 

If you are looking for more standby and listening time, there are a few choices from the LONGLIFE series. The closest in size to the Micro GSM Bug is the LONGLIFE 10 featuring up to 10 days of standby and 4-6 hours of listening time. 

As slightly bigger options, you can check out the LONGLIFE 20LONGLIFE 20+, or LONGLIFE 20 PRO K+ featuring up to 20 days of standby and 10 hours of listening time. The LONGLIFE 20 has an integrated microphone, while the LONGLIFE 20+ and LONGLIFE 20 PRO K+ have an extended microphone. Additionally, the LONGLIFE 20 PRO K+ stands out with a longer extended microphone and a high-quality Knowles microphone.

For long-term monitoring, we suggest you take a look at the LONGLIFE 60 which provides you with an impressive 75 days of standby and 26 hours of listening time.
