Sony CRE-C10

Sony teamed up with WS Audiology (the second-largest hearing company in the world) to co-create its products. Sony's CRE-C10 devices are nearly invisible and offer prescription-grade sound quality controlled through your smartphone. CRE-C10 does not offer Bluetooth streaming or rechargeable batteries.

CRE-C10 uses a size 10 disposable battery that offers over 70 hours of continuous wear. Size 10 batteries are widely available and commonly used in small devices. Sony's hearing aids were released in mid-October, so there are few reviews of the product, but it's safe to say this will be a leading consideration for those who want an in-the-ear style device.

CRE-C10 comes with a Sony app that allows users to control the volume and sound quality of the devices. No audiologist visit is required.
