Maximize your hearing with both ears.

Man wearing Cochlear implant and hearing aid

Hearing with both ears offers a clear advantage, especially when it comes to distinguishing where sound is coming from and understanding speech in noisy environments.

Depending on your degree of hearing loss, you may benefit from using a hearing aid in one ear and a cochlear implant in the other (commonly referred to as bimodal hearing). Or, you may find it more beneficial to have a cochlear implant in both ears (bilateral hearing). With both bimodal hearing and bilateral cochlear implants, you may find that understanding speech is much easier, and you’re able to enjoy a more complete hearing experience, especially in noisy environments.

Many individuals who use a cochlear implant in one ear continue to benefit from a hearing aid in the other.1,2 For this reason, Cochlear, the global leader in implantable hearing solutions, has partnered with GN ReSound, the leader in Smart Hearing™ aids, to pioneer the world’s smartest bimodal hearing solutions.
