Product Description

Signia’s newest CROS devices deliver an augmented hearing experience for clients with untreatable hearing loss in one ear. Built on Signia’s leading-edge Augmented Xperience platform, they use Signia’s proprietary Augmented Focus technology to split speech from surrounding sounds, process them separately, and recombine them to deliver outstanding speech clarity in an immersive environment.

CROS Pure 312 AX
The smallest CROS device for outstanding speech clarity.

The CROS Pure 312 AX is equipped with all the benefits of Signia’s Augmented Xperience (AX) platform for outstanding speech clarity. CROS Pure 312 AX attracts wearers with its fresh, elegantly slim design. Despite its discreet form, this tiny device provides fully featured Bluetooth connectivity for Android and iPhone plus all the benefits of the Signia Assistant.

What is a CROS?
CROS stands for Contralateral Routing of Signal. This is a hearing solution of choice to those with single-sided deafness. This means one ear hears better than the other side.

The CROS picks up the sounds from the poor hearing ear and transfer it to the compatible hearing aid on the better hearing ear. If the better hearing ear has normal hearing, it is set up as a CROS configuration. If some hearing loss is present on the better ear, it is set up as a BiCROS configuration (Bilateral Contralateral Routing of Signal).

The CROS device is meant to be used with a compatible hearing aid on the other side. It cannot be used alone or by itself.

The Signia CROS Pure 312 AX is compatible with the Signia Pure 312 AX hearing aids in the performance levels of 7AX, 5AX and 3AX.

After looking at the marketplace for hearing aids and looking at multiple videos and written information, I chose my preferred brand and starting to review pricing and Audiologist options close by. I must say that the level of service and keenest to help and answer any of my needs at Hearings Aids 365 was excellent and responsive. Importantly, I could purchase my desired brand at close to half the cost of others, as well as accessories such as TV Wireless Connector, and I also had access to many Audiologists that were eager to help with a hearing test, set up and service, even though I had not purchased from them. I would certainly recommend anyone to speak with Hearing Aids 365 for their specific requirements.

Thank you HearingAids365. One gets tired of having to pay for a service package of two or so years that is never required if the aids are set correctly in the beginning. Extremely satisfied. Service is also much appreciated. Keep up the great work.”

I always get 3 quotes for major purchases and hearing aids 365 were significantly cheaper for top of the range Phonak hearing aids. The response time to any query I had was immediate. Great value for money.

I am writing to thank you and to let you know that so far all has gone according to plan and this morning, I have had the aids programmed. I am currently wearing them and thus far I am completely happy with them. I am very happy with your service and was also the happy recipient of a $100 Visa Card from you as thanks for my patience when waiting for the order which had been delayed. Thank you again for your attention to our needs and for your diligence in keeping us up dated on the status of our order. I will not hesitate to recommend you to family and friends.
