If you are nervous, careful not to use excessive force on the sliding part of the hoop as it seems quite fragile because of its moderate thickness. I loved the classy black HP logo on each foldable headset to save space when storing.
One d1m50 cable attached to the left ear and manages all avoids having two separate cables on each side. It includes a remote control that has a microphone and adjusts the volume (via a knob). A button provides playback and pause (1 pressure), the chunk of change (2 pressures) and call management (answer / end).
Note that the microphone and the button will only work with compatible devices (it works on my Nexus 7 tablet), made possible through the mouthpiece 4 jack mandatory points for the management of headphones, microphone and remote control functions.
No adapter to 3.5 mm jack input 2 (green benchmark for the sound & red for micro) being provided, it will benefit only the audio system with the volume control on the 3.5 mm jack conventional systems. Damage (hence the drop on the note).
The H2800 comes with several mini booklets: the User Guide and 2 additional instructions (information and warranty).
It's a great helmet at a low price (about 25) rather dedicated to listening to music in the street, public transport, in your bed or on the go. A compatible audio device (eg a recent shelf) will be mandatory for micro and enjoy the hands-free function.
