RONDO 2
Single-Unit Audio Processor
It’s Never Been Easier
Why is RONDO 2 so revolutionary? For the first time ever, there’s no need to change batteries or manipulate switches. Think of the possibilities: Hearing without any hassles. RONDO 2 is incredibly easy to use—making it perfect for anyone who wants an audio processor that combines discreet style and care-free simplicity.
- Incredibly Simple
- Wireless Charging
- Sleek Design
Ease of Use
By combining wireless charging, a unique all-in-one design, and hands-free control, RONDO 2 is the easiest-to-use audio processor ever made. This makes it incredibly easy to use, even for users with limited dexterity or eyesight. And with a sleek, stylish design, it’s also the perfect choice for patients who want a discreet wearing option for their CI.
Wireless Charging
RONDO 2 uses Qi technology to wirelessly recharge its integrated lithium-ion battery. This means no more fumbling to open the processor to change batteries. Just place it on the charging pad and RONDO 2 starts charging.
All Day Battery
Set it on the charger at night and wake up to a full day of battery. Four hours of charging provides a full day of battery (up to 18 hours). The Mini Battery Pack also provides a back-up option to directly power RONDO 2 with a AAA battery.
One Touch Control
No cables, no switches, no worries. Just press one button and you’re ready to go. And RONDO 2 uses our proven Automatic Sound Management for hands-free control.
Microphone Covers
Blend in or stand out. RONDO 2 covers change in a snap, making it easy to change between more than 30 stylish designs and subtle patterns.
Water Resistance
RONDO 2 is water-resistant to protect against rain, sweat, and everyday moisture. And with the sleek WaterWear cover, RONDO 2 is fully waterproof for swimming.
Connectivity
With a built-in telecoil, RONDO 2 makes it easy to stream wireless audio from hearing loop systems or from a phone through a Bluetooth® neckloop.
More Natural Hearing
When it comes to sound quality, it’s the whole system that counts. RONDO 2 uses our proven combination of Automatic Sound Management and unique MED-EL implant technology to deliver a more natural sound quality for a more enjoyable hearing experience.
Natural Loudness Growth
Our Dual-Loop Automatic Gain Control instantly adapts volume levels to make loud sounds more comfortable and soft sounds easier to hear. With an extended loudness growth range and compression ratio (3:1), our loudness growth more closely follows natural loudness growth in the cochlea.
This is an advantage for loudness balancing with bilateral CIs, or if the other ear has natural hearing, such as single-sided deafness or for bimodal listening with a contralateral hearing aid.
Structure Preservation
Our incredibly flexible lateral wall arrays can gently adapt to the shape of each individual cochlea to protect the delicate natural structures. Multiple recent studies have shown only MED-EL arrays enable 100% scala tympani insertions.
Scala tympani placement enables significantly better hearing outcomes. It also helps preserve delicate cochlear structures so patients can benefit from future therapies.
Complete Cochlear Coverage
In natural hearing, the nerve fibers of the spiral ganglion are tonotopically organized and extend the full length of the cochlea. If an electrode doesn’t cover two full turns (720°) of the cochlea, it can’t stimulate these nerve fibers to provide accurate pitch-place match.
Our long, flexible arrays can be safely inserted all the way to the apical region to provide natural tonotopic stimulation across two full turns of the cochlea. With complete cochlear coverage, recipients can enjoy a natural pitch match from the very
beginning. This enables significantly better hearing performance and a more natural hearing experience for your patients.
FineHearing Sound Coding
In nature, the cochlea uses two types of sound coding. Place-pitch tonotopic coding is used along the whole frequency range. In addition to place-pitch coding, low-frequency sounds are also coded by rate. With this time-coding, the frequency of nerve signals is synchronized to the frequency of the sound below ~1000 Hz.
That’s why we created the only cochlear implant sound coding that mimics the natural time-coding for low frequencies and provides place-pitch match throughout the cochlea. By mimicking natural sound coding, FineHearing provides much more natural sound quality.
Peace of Mind
When it’s easy for them, it’s easy for you. With RONDO 2, you can rest assured that your patients will have a reliable, easy-to-use audio processor. There are only 3 components (processor, microphone cover, and magnet), so there is no need to replace cables or fiddle with opening the processor. This all-in-one design makes RONDO 2 both highly durable and user friendly for all ages.
