Instant-fit hearing aids like Signia Silk use soft sleeves and can be fitted the same day, from ₹46,990 per ear (MRP). Custom aids such as ReSound Key, Unitron Insera, Signia Insio and Phonak Virto are made from an impression of your ear, start from ₹27,995 per ear, fit more securely and cover more hearing loss, but take longer to make.
The short answer
Choose instant-fit if you want a small in-ear aid fitted in a single visit without an ear impression, and your loss is mild to moderate. Choose custom if you want the most secure, comfortable fit, more power or more vent options, and can wait while the shell is made. Instant-fit Signia Silk starts at ₹46,990 per ear (MRP); custom in-ear aids start from ₹27,995 (ReSound Key 3 CIC).
How to read these prices: MRP is the manufacturer's printed price from the 2026 price lists we hold (Signia 17 March 2026; Phonak and Unitron 1 June 2026; ReSound 2026). Prudent typically sells 30% to 50% below MRP depending on the model, so the likely price shown is for one ear unless marked per pair. Your exact quote is confirmed after your free hearing test, and hearing aids are GST-exempt in India. Prices change with each new price list; see the latest on our pricing page.
