- Less power of the amplifiers and speaker unit (receiver) due to smaller size.
- Single omni-directional microphone that picks up sound arriving from all around you. Therefore less adaptive directionality of microphones to pivot their focal patterns away from noise.
- Limitations of ear canal anatomy. May be too small to be made as a true IIC to house all the components.
- There may be management difficulties if you have poor vision or manual dexterity.
- Too small to come with the option of a Telecoil.
- As they sit deeper in a humid/moist ear canal they are more susceptible to breakdown due to ingress of ear wax (cerumen) and moisture
- As they have a smaller surface area they are more likely to:
- feedback (e.g. whistle) due to acoustic leakage
- work loose or migrate out whilst talking and chewing,

Signia Insio 3Nx is an impressively small custom fitting hearing aid that can fit deeply in your ear canal so it’s out of sight. It falls into he category of invisible in the canal (IIC). Being made to fit the natural anatomy of your ear can improve both the comfort and the security of the fit. They make excellent use of the natural shape of your ear to direct sound into the canal and therefore preserve the natural inter-aural timing and intensity cues that enable you localise where sounds are coming from. These vital cues also enable you to separate the speech you want to attend to from other competing sounds around you.
With the premium digit processing 3 Nx chip platform has 24 digital processing channels. This descent number provides accurate shaping of the amplification to your hearing levels across the frequency range. Also you receive effective noise filtering to provide comfort and clarity in busy social environments with competing noise.
Some of the main benefits of an Invisible in the canal (IIC) style hearing aids are:
- Their miniature size and invisible appearance.
- The location of the microphone in the ear canal helps with:
- natural positioning when using a telephone.
- the preservation of the natural acoustics provided by the external ear (Auricle or Pinna) that help with localising the direction of sound.
- Reduces wind turbulence as tucked further in away from wind.
Some of the limitations of invisible in the canal (IIC) style hearing aids are:

Great for semi-experienced looking to build on knowledge.
Format: Paperback
Fantastic instructional manual if you already have some basic knowledge of anchors, ropework and climbing technique. It is written as an instructional manual for climbers looking to turn into guides so if you're brand new this probably isn't the best option for you.

Clear, straight forward, and authoritative
Format: Paperback
Excellent, straightforward information about how to stay safe at the crag. Every guy who's put his hand on a rock has an opinion about how to set anchors, belay, etc -- this book gives you the answers on how to do things the right way. Spend the 10 or 15 bucks and read the book. It might save your life.
