This is part of CNET's "Tech Enabled" series about the role technology plays in helping the disability community. When Shannon Conn puts her hearing aids in her ears in the morning, a few things happen. The coffee maker starts brewing. When someone rings the doorbell, the chime streams straight into her ear. Conn, a 43-year-old special education advocate from College Grove, Tennessee, wears the Oticon Opn, which features the ability to link up with other connected devices.
