ReSound Nexia 4 ITC Review (2026): Price in India, Features, Pros & Cons

The ReSound Nexia 4 ITC is a custom-moulded hearing aid, meaning no two devices are physically identical. During the fitting appointment — available at any of HearClear's 40-plus clinics — an audiologist takes a silicone impression of your ear canal and outer concha. That impression is sent to GN ReSound's manufacturing facility, where the device shell is precision-fabricated to match your anatomy. The result is a snug, stable fit that does not shift during jaw movement or physical activity, which is a real-world advantage over universally sized canal tips used in RIC designs.

The ITC profile means the device sits partially in the ear canal and partially in the lower bowl of the outer ear. At conversational distances, it is largely inconspicuous — the faceplate is the only visible component, and it can be finished in skin-toned shades. The faceplate also houses the rechargeable port and, depending on configuration, a small push-button for programme or volume changes. Users with reduced finger dexterity should discuss button placement with their audiologist at fitting, as the tactile area is naturally constrained by the shell size. Overall, the device's weight — approx. 2–3 grams — means long-duration wear throughout an Indian workday causes minimal fatigue.

The Nexia 4 platform provides 12 adaptive processing channels, which divide the audible frequency range into independently managed bands. Each channel can apply different gain, compression, and noise suppression values, allowing the aid to simultaneously protect comfort in low frequencies while boosting speech clarity in the mid-high range. This is meaningful for the varied acoustic environments of Indian daily life — from a relatively quiet home to a crowded sabzi mandi or an air-conditioned office with HVAC hum.

GN ReSound's multi-stage noise management system operates in real time, classifying environmental sound as speech, steady-state noise, impulse noise, or music, and applying appropriate suppression without the over-processing that causes speech to sound hollow or robotic. The adaptive directional microphone system — built into the ITC shell — steers sensitivity toward the dominant speech source in front of the wearer. It is worth noting that the ITC form factor accommodates a single microphone configuration in most custom shell sizes, which limits the directional advantage compared with a dual-microphone RIC or BTE. However, the Nexia platform's signal processing partially compensates by using temporal and spectral cues to prioritise speech. For the entry-to-mid technology tier, this is a well-balanced trade-off between discreetness and acoustic performance.

Feedback suppression is active and effective — the tight custom seal of the ITC shell naturally reduces the acoustic leakage that causes whistling, further complementing the electronic suppression algorithm.

The ReSound Nexia 4 ITC connects via Bluetooth Low Energy to compatible smartphones. On the iOS side, it supports Apple's Made for iPhone (MFi) protocol, enabling direct audio streaming from iPhone 7 and later models without an intermediate streamer device. Android compatibility has expanded with the platform — ReSound lists a range of approved Android handsets; wearers using Samsung Galaxy S-series, Google Pixel, and several mid-range Redmi and Realme models commonly available in India will generally find stable streaming, though confirming your specific handset model with the HearClear audiologist at fitting is advisable.

The ReSound Smart 3D application (free, iOS and Android) is the primary user interface. It allows real-time adjustment of volume, bass/treble balance, and directionality. The app also stores multiple user-defined favourite settings — useful for wearers who regularly switch between a noisy workplace and a quiet home. A noteworthy feature is Remote Assist: the audiologist at HearClear can push programme adjustments to the hearing aid over the internet without requiring the wearer to travel to the clinic. This is particularly convenient for users in smaller cities or those with mobility constraints. The tinnitus sound therapy library within the app — offering white noise, ocean sounds, and notched audio options — adds genuine functional value for the estimated 10–15% of Indian adults who have clinically significant tinnitus alongside hearing loss.

The shift to rechargeable ITC hearing aids is relatively recent in the industry, and the Nexia 4 ITC's lithium-ion cell is one of its most practical selling points for the Indian market, where humidity, dust, and the inconvenience of sourcing size-10 or size-312 zinc-air batteries in smaller towns are real concerns. The included custom charging case holds the device securely — the custom shape of the case matches the shell impression, which prevents the 'rattling around' problem sometimes seen with stock chargers paired to custom shells.

Expected battery life on a full charge is approximately 16–20 hours of use without active Bluetooth streaming. With continuous audio streaming — for instance, listening to music or watching video content throughout the day — expect closer to 12–14 hours before needing to recharge. For the average Indian adult who puts on their hearing aid at 7 AM and removes it by 10–11 PM, a single overnight charge is sufficient for a full day's use. A two-hour charge from empty to full is typical for this platform. It is important to note that the battery is sealed within the custom shell and is not user-replaceable; battery service would be handled through HearClear under the 3-year warranty or at out-of-warranty service rates after that period. Users travelling frequently should carry the charger, as a universal USB-C option is not available for this model's proprietary charging contact.

The ReSound Nexia 4 ITC is priced at ₹96,995 per device at HearClear India. For a bilateral fitting (both ears), the total investment would be ₹1,93,990. This positions it in the upper bracket of entry-to-mid tier custom ITC hearing aids available in India, reflecting the rechargeable convenience, Bluetooth connectivity, and the cost of custom fabrication that stock-fit devices do not incur.

What is included at this price: the custom-fit ITC hearing aid shell, the proprietary custom charging case with lithium-ion charging contacts, a cleaning tool, a wax filter replacement kit, and an initial programming and fitting session by a qualified audiologist. HearClear's 3-year manufacturer warranty is included, covering defects in materials and workmanship. A 3-day risk-free trial is available at participating HearClear clinics — you wear the fitted device in your actual daily environments before committing to the purchase.

For buyers concerned about the upfront cost, HearClear offers no-cost EMI options through leading banks and fintech partners, making monthly payments feasible in the ₹2,700–₹5,400 range depending on tenure. Custom re-shelling (if your ear canal changes due to weight loss, surgery, or age) is available as a paid service. Remote fine-tuning via the Smart 3D app can reduce the number of return visits required after the initial fitting, which is a cost and time saving for patients travelling from outside the clinic city.

Buy the ReSound Nexia 4 ITC if: You have a confirmed audiogram showing mild-to-severe hearing loss and your audiologist has cleared you as a suitable ITC candidate (broadly, ear canals of adequate size and without chronic ear discharge). You place high value on cosmetic discretion — particularly in professional settings such as corporate offices, formal meetings, or social situations where you prefer that your hearing aid be largely unnoticed. You want rechargeable convenience without the bulk of a behind-the-ear device. You are a regular smartphone user comfortable with app-based control and appreciate the flexibility of remote fine-tuning. You also want basic tinnitus relief built into your hearing device.

Consider alternatives if: Your hearing loss is in the profound range (above approximately 90–95 dB HL), as the ITC shell's physical size limits the maximum power output achievable, and a RIC or BTE would serve you better. If manual dexterity is significantly impaired — due to arthritis, neurological conditions, or age-related fine motor changes — the small buttons and custom-fit charger connection of an ITC can be challenging; a RIC with larger controls would be more appropriate. If your budget is firm and cosmetic discretion is secondary, the ReSound Nexia 488 or Nexia 461 RIE offer comparable Nexia 4 processing in an RIC form factor at lower price points. If you require a telecoil for use with looped public venues (temples, auditoriums, railway counters), the ITC shell cannot accommodate one — a BTE or larger RIC form factor is necessary.

Because the Nexia 4 ITC is a custom device, the fitting process is more involved than with a stock RIC. At HearClear, the journey begins with a free comprehensive hearing test — pure-tone audiometry plus speech discrimination testing — conducted by a registered audiologist. If the ITC form factor is clinically appropriate for your audiogram and ear anatomy, ear impressions are taken during the same visit using medical-grade silicone impression material. The impression is dispatched to GN ReSound's manufacturing facility, and the finished shell typically returns within 7–10 working days. A dedicated fitting appointment then follows, during which the audiologist programs the device to your audiogram using first-fit algorithms and makes real-ear adjustments where needed.

Post-fitting, HearClear schedules follow-up appointments at 2 weeks and 6 weeks, which are critical for a custom device — fine adjustments to the shell for comfort and to the programming for real-world performance are normal and expected parts of the ITC fitting process. The 3-year warranty covers manufacturing defects; accidental damage protection can be added. Ongoing servicing — wax filter replacement, receiver cleaning, software reprogramming as your hearing changes — is handled at any HearClear clinic nationally, which is a meaningful benefit if you relocate or travel frequently within India. Remote Assist via the Smart 3D app means that minor programme adjustments between clinic visits do not always require an in-person appointment, saving time for patients in metros and smaller cities alike.
