Phonak CROS P

Phonak is one of the most well-known brands on the hearing aid market, they are one of what audiologists refer to as the “Big 6” hearing aid manufacturers. Phonak’s line of hearing aids are one of the broadest in the industry, and even their CROS products can be found across a few of their hearing aid lines. The Phonak CROS P is not Phonak’s first attempt at a unilateral hearing solution. In fact, as far back as the early 2000s, Phonak had a FM-based CROS system called “CROSLink” and then their first wireless CROS device in 2011. Phonak is known for quality and innovation in the CROS category and the CROS P hearing aids are no exception.

The CROS P is a solution for unilateral hearing loss from the Phonak Paradise line of hearing aids. The CROS P helps people suffering from complete hearing loss when speech or other sound is presented to the non-hearing ear. The Phonak Paradise line of hearing aids contains their most technologically advanced features and connectivity, and the CROS P uses that technology in a CROS system. The CROS P is one of the most “in demand” CROS systems based on the success of the Paradise line of hearing aids, and they have not disappointed. The following is a review and description of the Phonak CROS P hearing aids.

Why Are CROS Hearing Aids Important?

The term “CROS” is actually an acronym that stands for “Contralateral Routing of Signals.” CROS hearing aids are the solution for people who have profound hearing loss in one ear and rely on their good ear for all of their hearing. Many people can hear very little in one ear, sometimes to the point that a hearing aid will not help. If you can only hear in one of your ears, your head actually prevents your good ear from hearing things on the other side of your body. In some environments, this phenomenon is not that big of a deal, but in bars, restaurants, or other crowded social gatherings you can miss the majority of vocal communication if it happens on the side of your body where your “bad” ear is.

CROS hearing aids help to fight this type of hearing loss. With CROS hearing aids, even though you can only hear out of one ear, you wear hearing aids in both. Sound is detected by both hearing aids, but the sound detected by the hearing aid in your “bad ear” is transmitted directly to your “good ear.” You are then hearing all sounds and all frequencies heard on both sides of your head in your one good ear. You are a candidate for CROS hearing aids if you have severe hearing loss in one ear or cannot hear in one ear at all, and approximately 60,000 people in the U.S. develop this problem every year.

The Phonak CROS P hearing aid consists of two parts:

  1. The CROS with a microphone that is in the ear with poor hearing picks up sounds and voices from that side of your body. Those sounds and voices are transmitted, unprocessed, to the hearing aid that sits in your “good” ear.
  2. The Audeo Paradise hearing aid sits in your good ear and receives the sounds from the CROS device. The Audeo Paradise hearing aid processes those sounds with all of the technology available and plays the processed sound to your good ear.

Things to Consider Before Buying

CROS hearing aids are available to be used with quite a few of the higher end hearing aid lines in different brands. Oticon, Phonak, Lively, Bose, Kirkland, and ReSound are just a few of the brands that offer a CROS solution. The thing that differentiates the Phonak CROS P is that it uses the technology and features of one of their most popular and technologically advanced hearing aids to provide hearers with the best sound quality and listening experience possible. Basically, not all CROS hearing aid systems are created equal, so it is important to look deeper into each one prior to making a decision on a hearing solution for unilateral hearing loss.
