Best ReSound CROS Hearing Aid in India 2026 – Models & Prices

If you have little or no hearing in one ear and good hearing in the other, a regular hearing aid cannot help. What you need is a CROS or BiCROS system — and ReSound is one of the most trusted names in this category worldwide. In India, ReSound offers a full range of CROS systems across two modern platforms, at price points that span from mid-range to premium.

This guide covers every ReSound CROS model available in India in 2026 — what they cost, how they compare, who each one suits, and what honest buyers should know before spending their money.

CROS stands for Contralateral Routing of Signal. Here is what that means in simple terms:

• You have one ear that cannot hear — this is your "deaf ear" or non-aidable ear.
• You wear a small transmitter on that deaf ear. The transmitter picks up sound coming from that side.
• It wirelessly sends that sound to a hearing aid on your better ear.
• Result: you can hear people talking on your bad side without turning your head.

BiCROS is a variation for people who have hearing loss in both ears — but one ear is so severely damaged it cannot be helped with amplification alone. The hearing aid on the better ear both receives the transmitted signal and amplifies sounds for that ear.

Why does this matter in India? In a country where you constantly deal with conversations in crowded environments — a wedding hall, a temple, a busy market, a packed local train — missing sounds from one side is not a small inconvenience. It means missing half the conversation at every family function, every business meeting, every auto ride.

ReSound's CROS technology solves this with wireless transmission that is virtually undetectable in daily use.

ReSound uses a dedicated wireless CROS Transmitter — a small device that looks identical to a hearing aid — worn on the non-hearing ear. It communicates with the hearing aid on the better ear using Bluetooth. The transmission is continuous and real-time.

Key aspects of ReSound's CROS implementation:

2.4 GHz Bluetooth transmission — The signal between the CROS transmitter and the hearing aid uses the same Bluetooth platform that connects ReSound hearing aids to phones. This means the transmission is stable, has very low latency (no echo effect), and is secure.

All-Access Directionality — On the Vivia 9 platform, the hearing aid does not just dump the CROS signal into your ear. It blends it intelligently with what you are hearing on your good side, giving you a sense of where sounds are coming from. This is called Spatial Sense — it helps your brain make sense of the 360-degree sound picture.

Rechargeable CROS Transmitter — All current ReSound CROS systems use Li-ion rechargeable transmitters. This is a significant advantage in India, where finding replacement hearing aid batteries (especially size 10 or 312) in a small town can be genuinely difficult. You charge the transmitter in the same premium charger as the hearing aid, overnight, and you are set for the day.

IP68 Protection — Both the hearing aid and the CROS transmitter carry iSolate nanotech coating with IP68 water and dust resistance. In India, where the monsoon means daily exposure to humidity and sweat, IP68 is not a luxury — it is essential.

Compatible with LP/MP/HP receivers — The CROS transmitter works with Low Power, Medium Power, and High Power receivers on the Vivia and Nexia platforms. This means the audiologist can select the right receiver for your degree of hearing loss on your better ear.

ReSound currently offers CROS systems on two platforms: Vivia (their newest, AI-driven platform launched 2025–26) and Nexia (the previous generation flagship). Both platforms are fully current and supported.

Vivia CROS Systems

The Vivia platform is ReSound's most advanced. It runs a DNN (Deep Neural Network) AI chip that continuously analyses your listening environment and adjusts processing. The Binaural Directionality III and All-Access 360 All-Around features are exclusive to the Vivia 9 tier.

Each kit includes: 1 hearing aid (MicroRIE) + 1 CROS transmitter (MicroRIE) + 1 Premium Charger.

Note: The CROS Transmitter component carries a 1-year warranty regardless of the kit tier. The hearing aid itself carries the tier warranty (24–48 months).

The standalone Vivia CROS Transmitter MicroRIE is also sold separately at ₹54,995 for buyers upgrading an existing Vivia hearing aid to a CROS system.

Nexia CROS Systems

The Nexia platform is the previous flagship generation. It shares much of the same processing as Vivia (same Binaural Directionality III, DFS Ultra III feedback cancellation, Tap Control, iSolate IP68) but lacks the Vivia-exclusive DNN AI chip and Spatial Sense features. It is a proven, mature platform with an excellent track record.

Nexia also offers a BTE CROS option:

The Nexia CROS Transmitter NP BTE (with Desktop Charger) is priced at ₹63,495 and is designed for use with Nexia BTE hearing aids. This is useful when the patient's better ear requires a Behind-The-Ear form factor — for example, in cases of severe-to-profound hearing loss on the better ear where a NP BTE receiver delivers more gain.

The standalone Nexia CROS Transmitter MicroRIE is sold separately at ₹54,995.

At the same price point, Vivia 9 is the better choice if you want the latest AI processing. At mid-range (level 5 or 7), the practical difference is smaller and both platforms perform very well.

Rank 1: Vivia 9 CROS MicroRIE — ₹4,79,995

Best overall ReSound CROS system.

The Vivia 9 is ReSound's flagship, and the CROS version puts that flagship processing into the hands of single-sided deafness patients. The 17-channel processing, DNN AI chip, and Spatial Sense mean you get the most natural blending of sound from both sides. In noisy Indian environments — a busy restaurant, a temple with music and crowds, a market — the 5-setting environmental noise reduction and Binaural Directionality III work together so that the CROS signal from your deaf side is clean and usable, not just raw noise.

The 48-month warranty on the hearing aid is the longest available in this category, which matters for a premium purchase. Bluetooth LE Audio and Auracast mean future-proofing for TV streaming and public audio systems.

Who it is for: Anyone who wants the best CROS experience money can buy in India, and plans to keep the system for 4+ years.

Rank 2: Vivia 7 CROS MicroRIE — ₹2,96,995

Best value ReSound CROS system.

The Vivia 7 sits at 14 channels and carries the same 48-month warranty as the Vivia 9. It skips the DNN AI chip and Spatial Sense but retains Binaural Directionality III, IP68, rechargeable, Android ASHA, and MFI connectivity. For the majority of single-sided deafness patients who do not need the AI-layer of the level 9, the Vivia 7 CROS is the sweet spot. The price drop from ₹4,79,995 to ₹2,96,995 is significant — nearly ₹1.8 lakh — with very little practical compromise for everyday listening.

Who it is for: Active adults who want a reliable CROS system with long warranty, without paying for AI features they will rarely notice.

Rank 3: Nexia 9 CROS MicroRIE — ₹4,79,995

Best option if you want proven technology at the same price.

Priced identically to the Vivia 9 CROS, the Nexia 9 CROS is a strong choice if your audiologist recommends it — perhaps because they have more fitting experience with the Nexia platform, or because the Nexia's fitting software gives a better match for your specific audiogram. It lacks Vivia's DNN and Spatial Sense but the difference in real-world CROS performance is marginal for most users.

Who it is for: Buyers whose audiologist recommends the Nexia platform, or those who prefer a more mature, well-documented system.

Rank 4: Vivia 5 CROS MicroRIE — ₹1,91,995

Best mid-range ReSound CROS.

At under ₹2 lakh, this is the most accessible Vivia CROS kit. It drops to 12 channels and 36-month warranty, but retains IP68, rechargeable, and Binaural Directionality. For a patient with a limited budget who still wants the Vivia platform and a quality CROS experience, this is a strong option. Noise reduction and directionality are adequate for most environments, including family conversations and group settings.

Who it is for: Budget-conscious buyers who still want Vivia platform reliability.

Rank 5: Vivia 4 / Nexia 4 CROS MicroRIE — ₹1,41,995

Entry-level ReSound CROS.

At ₹1,41,995, this is the most affordable complete CROS kit from ReSound in India. The 12-channel processing handles quiet and moderately noisy environments well. The 24-month warranty is the shortest in the range. For someone who primarily needs CROS functionality for one-on-one conversations and quiet settings (home, small office), this is a viable entry point. Noisy environments will be more challenging.

Who it is for: First-time CROS users, buyers on a strict budget, or those who will primarily use the system in quiet to moderate environments.

Humidity and Monsoon: Both the Vivia and Nexia CROS transmitters carry IP68 certification with iSolate nanotech coating. This means they are designed to handle the humidity of Mumbai, Chennai, and Kolkata monsoons, as well as sweat during Indian summers. This is non-negotiable for a CROS transmitter worn on the ear all day.

Power Cuts: All ReSound CROS kits use Li-ion rechargeable batteries. A full overnight charge gives a full day of use. However, if you are in a area with frequent power cuts, invest in a small power bank or UPS for the charger. The charger itself is compact and works on standard voltage.

Android Compatibility: Most Indian buyers use Android smartphones (Samsung, OnePlus, Xiaomi, Vivo, OPPO). All Vivia and Nexia CROS systems support Android ASHA for direct audio streaming. You can stream calls, YouTube, and music directly to your hearing aid without any intermediate device.

Service Network: ReSound in India is distributed through GN Hearing's authorised network. Before buying, confirm there is an authorised ReSound service centre in your city. Remote fitting (ReSound Assist Live) is available on the Vivia and Nexia platforms, which means your audiologist can make adjustments via video call — this is particularly valuable if you live outside a major metro.

ADIP Scheme: Government employees and persons with disability can access the ADIP (Assistance to Disabled Persons) scheme for hearing aids. ReSound CROS systems at the ₹1,41,995–₹1,91,995 tier may qualify depending on the scheme's annual revision. Check with your ENT or audiologist for the latest eligibility criteria.

0% EMI: Most HearCure locations and partnered clinics offer 0% EMI options on hearing aid purchases above ₹50,000. A Vivia 7 CROS at ₹2,96,995 on a 24-month EMI works out to approximately ₹12,375 per month — comparable to many premium smartphone EMI plans.

TV Streaming: ReSound's TV Streamer accessory is compatible with the Vivia and Nexia platforms. For CROS users, the TV audio streams directly to the hearing aid on the better ear, bypassing the CROS transmitter for TV-specific use. This delivers clear, direct TV audio without needing to adjust room volume.

Q1: What is the difference between CROS and BiCROS in ReSound systems?

CROS is for people with zero usable hearing in one ear and normal (or near-normal) hearing in the other. BiCROS is for people who have hearing loss in both ears, but one ear is unaided — the hearing aid on the better ear both receives the transmitted CROS signal and amplifies sounds for that ear. Your audiologist will determine which configuration suits your audiogram. ReSound's Vivia and Nexia CROS systems can be configured for both CROS and BiCROS fitting.

Q2: Do I need to wear something on my deaf ear?

Yes. The CROS transmitter is worn on the non-hearing ear. It is a small device that sits behind or in the ear canal (for MicroRIE) and looks virtually identical to a hearing aid. Most users find it comfortable and discreet after a few days of adjustment.

Q3: What is the battery life of the ReSound CROS transmitter?

The CROS transmitter (both Vivia and Nexia versions) is Li-ion rechargeable and provides approximately 18–20 hours of use on a full charge, which covers a full waking day. Charging takes about 3 hours. The Premium Charger included in the kit charges both the hearing aid and the CROS transmitter simultaneously.

Q4: Can I use a ReSound CROS system with my Android phone?

Yes. The Vivia and Nexia CROS systems support Android ASHA for direct audio streaming. You can stream calls, music, and app audio directly to the hearing aid. The ReSound Smart 3D app (available on Android and iOS) allows you to adjust volume, change programs, and fine-tune settings from your phone.

Q5: Is the CROS transmitter warranty shorter than the hearing aid warranty?

Yes. The CROS Transmitter carries a 1-year warranty, regardless of the tier. The hearing aid itself carries the tier warranty — 48 months for level 9 and 7, 36 months for level 5, and 24 months for level 4. This is standard across the industry and is not unique to ReSound.

Q6: Can I buy just the CROS transmitter and use it with my existing ReSound hearing aid?

Yes, if your existing hearing aid is on the Vivia or Nexia platform. The standalone Vivia CROS Transmitter MicroRIE is priced at ₹54,995 and the Nexia CROS Transmitter MicroRIE at ₹54,995. The Nexia CROS Transmitter NP BTE (for BTE hearing aid users) is ₹63,495. Confirm compatibility with your audiologist before purchasing.

Q7: How does ReSound CROS compare to Phonak CROS?

Phonak offers the CROS Paradise and CROS Marvel systems, which also have strong reputations. The key differences: Phonak offers a wider range of form factors for CROS (including BTE and RIC variants across more tiers). ReSound's advantage is the Spatial Sense feature on the Vivia 9, which provides a more natural 360-degree sound impression, and the iSolate IP68 across all CROS tiers. Both brands are excellent — the best choice depends on your audiogram, listening priorities, and which brand your audiologist has more fitting experience with.

ReSound has built a comprehensive, well-thought-out CROS range that covers every price point from ₹1,41,995 to ₹4,79,995. Every kit is rechargeable, IP68 protected, and Bluetooth-ready — there are no corners cut at any tier.

• Best overall: Vivia 9 CROS MicroRIE (₹4,79,995) — most advanced CROS processing available from ReSound
• Best value: Vivia 7 CROS MicroRIE (₹2,96,995) — 48-month warranty, near-premium performance, significant saving
• Best mid-range: Vivia 5 CROS MicroRIE (₹1,91,995) — solid CROS on the new Vivia platform under ₹2 lakh
• Best entry: Vivia 4 or Nexia 4 CROS MicroRIE (₹1,41,995) — most affordable complete kit

For Indian buyers, the Vivia 7 CROS MicroRIE hits the best balance of features, warranty, and price. If budget allows, move to the Vivia 9 for the DNN AI chip and Spatial Sense — you will notice the difference in noisy environments like weddings, markets, and group conversations.

Book a trial with a ReSound authorised audiologist before committing — a proper fitting and a real-world trial period (most clinics offer 30-day trials) is the only way to know how well any CROS system works for your specific hearing profile.
