JD Health Tech JD-916BE Rechargeable Personal Sound Amplifier for Adults A compact in-ear sound amplifier for adults who want a little more clarity in everyday listening at home, with nothing to set up. It helps with the situations where sound can feel a bit too soft: conversation at the dinner table, watching TV at a normal volume in the same room, one-to-one chats and small family gatherings. SIMPLE TO USE, NO APP AND NO PAIRING There is no app, no Bluetooth and nothing to connect. Take the amplifiers out of the dock, switch them on and set the volume. That is the whole process, which suits anyone who would rather not deal with a phone. UP TO 35 HOURS PER CHARGE A full charge takes 2 to 3 hours and gives up to 35 hours of listening, depending on the volume you use. The amplifiers charge in the supplied dock, which plugs into mains power. The dock holds no reserve charge of its own, so it is not a portable power bank. DISCREET IN-EAR FIT, SEVEN EAR TIP SIZES The completely-in-canal design sits inside the ear, leaving very little visible from outside. Seven silicone ear tip sizes are included so most adults can find a comfortable seal. Fit matters more than people expect, because it affects comfort, clarity and whistling. Take a few minutes on your first day to work through the sizes. YOUR FIRST FEW DAYS Your own voice will sound louder than usual at first. This is normal and settles within a few days as you adjust. Start on a lower volume and build up gradually. If you notice whistling, change ear tip size before turning the volume up, as fit is almost always the cause.
