The retractable Headset with a 2.5mm plug (see also figure below) included in the
SAMBA3G-E-SET fully compatible with SAMBA3G-E phone is designed to do two things
at once, if those two things are driving and talking on the cell phone. The retractable
Headset is lightweight, super-easy to use, comfortable, and has great incoming and
outgoing sound quality. Retractable quality earpiece and microphone pulling out to
desired length independently. The retractable cord length is 78 mm. The headset
length is 1m. You have just to connect it to the corresponded connector of SAMBA3G-
E. To wear the earpiece, simply pull it out of its casing slowly until you reach the
sufficient length and sit it inside the ear. Should the length of the cable too long/short,
pull the cable slowly out or retract while holding the both sides onto the cable until the
length is suitable.
