Sometimes it can be hard to hear your best. Noisy public places can be difficult, as can talking on the phone or hearing the TV clearly.

RONDO 2 connects seamlessly with Bluetooth neckloops and hearing induction loops to bring the sound straight to your ears, even across a busy room. This gives you optimal hearing wherever you are, so you’ll never miss out on those important moments.
