Unitron Insera Blu 3 (B3-10 NW O) CIC
The Unitron Insera Blu 3 in the 10 NW O style is a custom-moulded invisible aid, built from an impression of your own ear canal so it sits inside the canal rather than behind the ear. It runs Unitron's Blu platform at level 3 on a size 10 battery. One point to be clear about before you buy: this style is non-wireless, with no Bluetooth streaming and no app, so choose it when staying unnoticed matters more than phone connectivity.

What the Insera Blu 3 is
The honest spec picture, using only what Unitron publishes for this style.
Unitron Blu, level 3
Built on Unitron's Blu platform at level 3, an essential-tier custom aid tuned to your audiogram.
Size 10 battery
Runs on a small size 10 disposable battery. It is a tiny cell, so steady fingers and decent eyesight help at change time.
Non-wireless, no streaming
The 10 NW O style has no Bluetooth streaming and no app. Wireless is offered only on the larger B-312 style, which we are happy to show you.
Made to disappear
Because it sits inside the canal, most people will not notice you are wearing it. That is the main reason to choose this style.
Moulded to your ear
The shell is made only for you, so comfort and retention are good once we finalise the impression and fitting.
Who it suits (and who should look elsewhere)
Where the Insera Blu 3 is the right call, and where another model fits better.
Discretion comes first
If being unseen matters more than anything, a custom CIC is the most discreet everyday option we fit.
You do not need streaming
If you are happy hearing your phone the normal way and do not care about Bluetooth audio, the non-wireless design costs you nothing.
Mild to moderate loss
Small custom CIC aids suit mild to moderate losses well. We confirm this is right for your audiogram at the test.
You want Bluetooth or an app
This style cannot stream. If connectivity matters, look at the Ativo RIC or a rechargeable Moxi, or ask us about the wireless B-312 Insera style.
Tiny controls are hard for you
A size 10 battery and a small custom shell need steady fingers. If dexterity is a concern, a RIC with a rechargeable case may be easier.
You may have a severe loss
Very small custom aids have power limits. If your loss is on the severe side, a RIC like the Ativo or Moxi with a P or UP receiver may suit better.
How the Insera Blu 3 compares in the Unitron range
Quick, honest comparisons with the nearest Unitron models we fit.
Ativo RIC
A behind-the-ear RIC that does hold two Bluetooth devices at once, if you decide connectivity matters more than being invisible.

Rechargeable with universal Bluetooth, but a behind-the-ear RIC rather than an in-canal custom aid.
View the Moxi S1-RMoxi S5-R
Adds speech-in-noise features and streaming in a rechargeable RIC, at a higher price and higher visibility.

Hearing aids guideFrequently asked questions
How much does the Unitron Insera Blu 3 cost in India?
The MRP is around Rs 52,000. At Prudent you can expect up to 30 to 50 percent off MRP, and the exact price is confirmed at your fitting. Hearing aids are GST-exempt, and 0% EMI is available.
Can the Insera Blu 3 connect to my phone?
No. The 10 NW O style is non-wireless, with no Bluetooth streaming and no app. Unitron offers wireless only on the larger B-312 style, which we are happy to show you. Choose the 10 NW O when discretion matters more than connectivity.
Is a custom CIC right for my hearing loss?
Custom CIC aids suit mild to moderate losses well and are less suited to severe loss or very small ear canals. Our audiologists confirm the right style for you after your free test.
Will people see the Insera Blu 3?
It sits inside your ear canal, so most people will not notice it. That discretion is the main reason to choose this style over a behind-the-ear aid.
The battery looks tiny; can I manage it?
It uses a size 10 battery, which is small. If handling tiny batteries is difficult, tell us; a rechargeable RIC with a charging case may be easier to live with.
Will it cure my hearing loss?
No hearing aid cures hearing loss; it manages it, helping you hear and follow conversation more easily. Our audiologists set realistic expectations during your trial.
