Oticon CROS
Oticon CROS uses the
premium technology of
Oticon’s Velox S™ platform
to enable transmission of
sound from the poorer ear
to the better ear.
Oticon CROS transmitter is a device
designed for people with single-sided
hearing.
CROS/BiCROS
Oticon CROS paired with a compatible
Oticon hearing aid is a Contralateral
Routing of Signal (CROS) amplification
system. Sounds are picked up by the
microphones in the CROS transmitter
located on the poorer ear. Then, they
are transmitted via Near‑Field Magnetic
Induction (NFMI) to a receiving hearing
aid located on the better ear. If some
hearing loss is present in the better
ear, the solution is set up as a Bilateral
Contralateral Routing of Signal (BiCROS)
configuration.
Open Sound Experience
Oticon CROS features a version of the
OpenSound Navigator™ designed for
transmitting sound to an Oticon hearing
aid. The solution provides 360‑degree
access to sound by scanning the
environment, balancing the sounds
and removing unwanted noise.
Dual Streaming With TwinLink™
With Oticon CROS solution, the connection
between the transmitter and receiving
hearing aid is made using the NFMI part of
Oticon’s TwinLink™ technology. TwinLink
technology makes it possible to connect
the receiving hearing aid to external audio
streams while simultaneously enjoying
sound transmission from the poorer ear
to the better ear. External audio is sent

directly to the receiving hearing aid using
2.4 GHz Bluetooth® Low Energy and
the Oticon CROS transmitter is sending
through NFMI. Clients can watch television
or listen to music and still be aware of
speech in the surroundings.
