P 640S: Where Simplicity Rules

The P 640S is a reliable, easy to use digital hearing aid that brings a great listening experience at a very attractive price.

In a world where technology is becoming increasingly complex, it can be rather a relief to come across something that is simply, well, simple! If uncomplicated is how you like to keep things, but you are never the less after a reliable and comfortable hearing aid, then you’ve come to the right place.

Choosing a hearing aid is tricky, not least because you need to be certain that you’re receiving a fair price, that delivery will be quick and that your hearing aid can be programmed specifically to your needs. At HearingDirect, you can be sure to receive:

  • A fast delivery service – order today and you can receive your purchase directly to your home within a few days.
  • A fantastic saving – as our prices are significantly cheaper than that of the high street.
  • Flexible programming capability – meaning that although the default setting is for a typical age related high frequency hearing loss, the P 640S can be altered to reflect your specific hearing requirements.
  • An Inconspicuous design – so that you barely know it’s there.
How could this hearing aid work for you?

Designed as an open fit, behind-the-ear digital hearing aid, the P 640S is both discreet to wear and easy to operate. User controls have been made as friendly as possible for fingers that aren’t quite as dexterous as they used to be. The volume control is wheel shaped and numbered. The battery used is one of the largest available. This means the battery life lasts longer, only to be further enhanced by a power-efficient chip platform, requiring less fiddly changes to contend with.

The P 640S is built with a range of sound processing features, including a feedback management system to protect your ears from uncomfortable and annoying whistling. Any unwanted feedback is automatically targeted and removed without influencing the amplification settings, leaving you to enjoy your conversation undisturbed. A telecoil programme is available as default and accessed via a push button, so connecting to your landline couldn’t be easier.

The P 640S is completely enclosed in a robust and extremely durable casing otherwise known as Nano-Coating. This makes the device not only water resistant but also offers maximum protection, generates fewer repairs and is easier to clean.

Key Features:

  • 4 sound processing channels
  • Water resistant and durable due to Nano Coating
  • Feedback management system
  • Telecoil programme
  • Analogue, numbered volume control
  • Comfortable open fitting
  • Simple to operate
  • Long battery life
  • Low battery warning
To summarize:

The P 640S is uncomplicated but strikingly up to date. It offers great technology at an astonishing price and there lies the attraction. When you purchase a P 640S, it is sent complete with a free pack of the required size 13 batteries, a thin piece of tubing and three different domes to help you find the most comfortable fit. Alternative tubing lengths are available to order upon request. If you live with a mild to moderate hearing loss, this product could be right for you. With a no quibble 30-day money back guarantee and a 12-month full manufacturer’s warranty, you really do have nothing to lose. Why not give it a try and see if simple really is best.

Brilliant service. I can hear again.

Review by Laura Daly (Posted on 9/30/2016)
So I live in Ireland and hearing aids are very very expensive and over the years I have paid out plenty for them, even with health insurance. I needed two new aids and did not feel like handing over another €1000 for them again. So I took a look around the internet and found hearingdirect.com. I read the reviews and did my research and set my budget. I decided on the P 604s I explained to the very nice lady on the phone that I had a small inner ear and she noted that. I placed my order on 27th Sept and it was here in Dublin via Royal mail International on 30th. Was well packaged and the aid was easy to set up and use so far using the power dome and no feedback. My only regret is the fact that I had not used the site earlier. Am going to order another aid for my right ear. Thank you So Much for the excellent service

Excellent product and excellent quality. Thank you. The difference between my old NHS and the ones I have bought, P640S, is outstanding and at 83 years old that is saying something. Thanks again.

Having already ordered a hearing aid for one ear as a trial, I decided to get a second for the other ear. I'm very satisfied both with the product and the service. I've also had various accessories and pleased with those, too.

Got advice from Melanie via the online advice and support facility. Price was right and product worked very well for my mother of 76. Is easy to use and made the world of difference for my Mom who is deaf in one ear. Melanie programmed the hearing test results herself and e-mailed me every step of the way. Had the hearing aid plus batteries in 7 days. First rate customer service.

Review by Steve Smith (Posted on 11/6/2014)
Fantastic product produces better results than I had ever thought it would feedback cancellation is fantastic don't be fooled by its small size it packs a punch and is a nice colour the nano coating is another feature I like about this product which repels moisture and is a comfortable fit the only way I know I'm wearing it is the lovely metallic sound produced something I love about it and since using it I've had no problems with losing my balance and bumping into people as I did before 1 would 110% reccomend this to anyone Also of a huge benefit is Melanie the audiologist who does her utmost to help people had a weeks delay due to supply problems with puretone and deliveries Melanie kept me informed and answered my questions Melanie is a massive credit to hearing direct and is fantastic
