Frequently Asked Questions - Hermes CoolBox
How do I pair the Hermes headphones with my phone?
Turn on the headphones by holding the power button until the LED flashes blue and red. On your phone, enable Bluetooth and select CoolBox Hermes from the list of available devices. If prompted, enter the PIN 0000.
Can I use the headphones while they are charging?
Yes, the Hermes supports passive use via the included 3.5mm AUX cable even when the battery is empty. For Bluetooth playback, we recommend charging fully before use to avoid interruptions.
How do I reset the Bluetooth connection?
If the headphones are already paired, delete the device from your phone's Bluetooth settings. Then press and hold the power button for 10 seconds until the LED flashes red and blue rapidly. This puts them in pairing mode and clears the previous pairing list.
What is the battery life of the Hermes?
The built-in rechargeable battery provides up to 20 hours of continuous playback at moderate volume. Actual battery life may vary depending on volume level and audio content.
How should I clean and maintain my headphones?
Use a soft, dry cloth to wipe the ear cups and headband. Remove ear pads periodically and clean them gently. Avoid using liquids or abrasive cleaners. Store the headphones in the included travel pouch when not in use.
Are the Hermes headphones compatible with gaming consoles?
Yes, you can connect them to consoles with a 3.5mm audio jack using the AUX cable. For consoles without an audio jack (like standard PS5), you may need a USB Bluetooth adapter to use wireless mode.
Can I use the AUX cable without power?
Yes, the passive mode works without battery power. Simply plug the AUX cable into the headphones and your audio source. The built-in microphone will not function in this mode, but you'll still get full audio output.
How do I charge the Hermes headphones?
Use the included USB-C cable and connect it to a power adapter or computer. A full charge takes approximately 2 hours. The LED indicator turns solid red while charging and blue when fully charged.
What should I do if the sound is distorted or crackling?
First, check the Bluetooth connection and move closer to the audio source. Ensure the headphones are fully charged. If using AUX, try a different 3.5mm cable and make sure the plug is firmly inserted. Also, lower the volume on both the device and headphones.
Are spare parts available for the Hermes?
Yes, ear pads and AUX cables can be replaced. Contact CoolBox support for authentic replacement parts. The headband and internal components are not intended for user replacement; open the device only if you have technical expertise.
