Product description from Tweak website:
Tweak is the only digital personal sound amplification product using specialized patented technology that lets you select from among three ranges of amplification, plus remember what level of amplification you like best.
Tweak contains the same components found in high-end hearing aids that cost thousands of dollars: digital amplification, high-end feedback cancellers, microphones, speakers, and bio-compatible plastics. It also incorporates a digital volume control to give you even more flexibility in different environments.
Tweak Hearing products are designed and programmed in the United States.

Dr. Schumaier gives a brief overview of the new Tweak models: Focus and Focus+T, including set-up information and a demonstration.
The Tweak Hearing Focus Model Personal Sound Amplifier came with 4 batteries each with a longevity of 7-8 days per battery. The units were smaller than I imagined but manageable even with big hands. My wife and I call this setting 'surround sound'. It is directional forward. With Tweak Focus on the 'noise' setting, volume 2, I am now hearing the audio clearly between 30-35%. Find this at: http://amzn.to/17TDlNK With my 2 Focus units on that setting my battery life was extended to 11 days and I replaced them prior to the warning tones. Using my old headphones with ear plugs the sound came from the ear plugs in my ears. Doesn't matter if I used them on a computer, TV, radio or amplifier. With the Tweak Focus I am hearing sound from the source, not from the ear plugs. If I listen to the TV set I hear the sound coming from the TV, just as if I wasn't wearing the amplifiers. Fantastic hearing help for an affordable cost! Battery life is not bad if you pop open the little battery door to turn the unit off when not using it. Your mileage may vary. Replacement parts (tubes and cones) are available through the company's website. One minor niggle, they use Paypal. Finally, some moderate to negative reviews have mentioned a 'tinny' sound. This Tweak Hearing Focus Model Personal Sound Amplifier Digital Volume Control Directional unit is mostly boosting mids to mid highs, which are exactly the frequencies I need it for.
