Q+ is a powerful hearing solution, designed to maximize your listening experience based either on the results of a simple interactive hearing test built into the app or from audiogram inputs.

With sophisticated technology inside, the Q+ app harnesses the processing power of your smartphone by giving you:

  • Inbuilt hearing tests calibrated for precision as per ANSI standards for accurate output.
  • Intelligently-adjusted sound as per hearing test results.
  • High-quality sound enhancement by using the same algorithms as hearing aids.
  • Wide bandwidth - up to 8000 Hz - by delivering higher bandwidth for improved comprehension and clarity of sound.
  • Automatic adjustment of amplification to reduce feedback (whistling sound) using proprietary cutting-edge adaptive feedback cancellation algorithms.
  • Versatile controls for customizing listening experiences.
  • Environmental noise reduction.

The app can be used with the phone's headset for improved speech comprehension and enhanced perception of environmental sounds.

Use the Q+ app to:

  • easily follow conversations (using earphones) in both quiet and noisy environments.
  • listen to sounds with enhanced clarity.
  • control the sound quality to customize it to your preference.

Inbuilt Hearing Test

Before the app can be used as a hearing solution, it needs to know your hearing loss levels (or thresholds). Alternatively, if you already know your hearing loss level via an audiogram, you can enter the thresholds directly into Q+.

The inbuilt hearing test in Q+ is calibrated for accuracy as per ANSI standards for audiometry, has advanced software to intelligently perform audiometry and monitors ambient noise if the location is too loud for a test.

Once the hearing test is completed (or the thresholds have been entered as per your audiogram), the app is ready to use.

Disclaimer: Though the hearing test is designed to be accurate, results may vary based on the depth of insertion of ear buds and ear pods into your ears, as well as the level of environmental sounds. Quadio recommends taking the test in a very quiet room. Test results should not be construed as an alternative to an audiological evaluation performed by a trained audiologist.

Fine-tuning Your Hearing Solution

The Q+ app is designed to allow you to control your listening experience. You can choose from three baseline sound quality types (bass/midrange/treble boost), can switch noise reduction on and off, and can fine-tune the sound type by controlling how different types of sounds are treated (soft sounds, loud sounds, speech and distant sounds).


Lower frequencies are enhanced more than higher frequencies. Masculine voices typically fall in this range. In music, drums are an example of sound that falls within this spectrum.


Consists of sounds with no boost. This sound enhancement mode provides a good balance between low and high frequencies.


Higher frequencies are enhanced more than lower frequencies. Feminine voices and children's voices usually fall in this range. Other examples are birds chirping and string instruments.

NOISE REDUCTION AND SPEECH ENHANCEMENT: Enable noise reduction and speech enhancement to hear better. These options work independent of each other and can be enabled or disabled depending on the clarity of sound that is suitable for you. You can also set the device volume to a level comfortable for you.

Further fine-tune the sound quality in advanced settings by tweaking for:

  • Sharpness of sound
  • Ability to hear distant sounds
  • Loud sounds
  • Your own voice

The app performs adaptive feedback cancellation to eliminate whistling or howling sounds which emanate because of the high amplification performed inside the app coupled with close proximity of the headset mic to the speakers. If needed, you can choose to use the phone mic instead of the one in the headset.


Currently, the Q+ app supports these earphones:

  • Apple EarPods and Apple EarBuds (for iPhones)
  • Nexus 5X stock headset (for LG Nexus 5x)
