P 640S Digital Hearing Aid

The medium length tubing included as standard fits more than 85% of our customers comfortably - but we will send out a shorter or longer tubing if need be. A number of different sizes and styles of dome designs can also be used. A smaller dome can help to minimise the ear canal feeling blocked up; but a bigger dome may be required to prevent amplified sound leaking back out the ear canal and creating feedback (whistling).

If anything about the physical fitting or sound is not to your liking, you can return the P640S for a full refund within the first 30 days of receipt. Do of course feel free to contact us to see if the problem can be resolved with a fine tuning.

If an evaluation by a hearing professional indicates that you have hearing loss in both ears, and especially where the degree of loss is similar, two hearing aids are usually recommended. 

While it may be tempting to try to limit the cost by going with a single hearing aid, wearing just one hearing aid may not give you maximum benefit in some difficult listening situations.

The following items will need to be replaced on the P640S:

• Battery: budget 3 batteries per month (6 batteries in a pack).
• Dome:  change the dome every month on average (10 domes in a pack).
• Tubing: change the tubing every 3 months (single tubings can be purchased, or in a pack of 5).

No on/off switch, just insert battery, close / open battery door.

There are two controls. The programme button to change between 2 settings. And the wheel-styled volume control which can be wheeled up or down to change volume softer or louder.
