How to connect the ESTM500 headset to my device?

Plug the headset cable into the 3.5 mm jack of your music player (phone, tablet, computer).

LISTEN RESPONSIBLY

To avoid hearing damage, make sure that the volume on your music player is tuned down before connecting your headphones. After placing headphones in your ears, gradually turn up the volume until you reach a comfortable listening level.

Noise level are measured in the decibels (dB), exposure to any noise at the or above 85dB can cause gradual hearing loss.

Monitor your use; hearing loss is a function of loudness versus time. The louder it is, the less time you can be exposed to it. The softer it is, the more time you can listen to it.

Do not use headphones when it's unsafe to do so - while operating a vehicle, riding a bike, crossing streets, or during any activity or in an environment where your full attention to your surroundings is required. It's dangerous to drive while wearing headphones, and in many places, illegal because it decreases your chances of hearing life-saving sounds outside of your vehicle, such as another car's horn and emergency vehicle sirens. Please avoid wearing your headphones while driving.
