If you or a loved one has severe to profound hearing loss, you have probably come across two names again and again: the Phonak Naída Lumity SP and the Phonak Naída Lumity UP. Both are behind-the-ear (BTE) power hearing aids built on Phonak's Lumity platform, and both are designed to deliver strong amplification for the toughest hearing losses. But they are not the same device, and picking the wrong one can mean the difference between comfortable, clear hearing and constant frustration.
In this guide, we break down everything you need to know about Naída Lumity SP vs UP — battery type, power output, frequency range, durability, features, and who each model is actually built for — so you can make a confident, informed decision.
What Is the Phonak Naída Lumity Series?
The Naída Lumity line is Phonak's flagship power hearing aid range, purpose-built for people with moderate, severe, and profound hearing loss. It runs on Phonak's Lumity technology platform, which uses real-time AI-driven sound processing to improve speech understanding in noisy environments, reduce listening effort, and offer seamless Bluetooth connectivity to smartphones, TVs, and other devices through the myPhonak app.
Within this range, Phonak offers a few BTE variants, but the two most requested by audiologists and patients are the SP (Super Power) and the UP (Ultra Power) models. If you're exploring your options, our full range of Phonak Naída Lumity hearing aids is a good place to compare pricing and technology levels side by side.
Phonak Naída Lumity SP vs UP: Quick Comparison
| Feature | Naída Lumity SP | Naída Lumity UP |
|---|---|---|
| Battery type | Size 13 disposable | Size 675 disposable |
| Power level | Super Power | Ultra Power |
| Best suited for | Severe hearing loss | Severe to profound hearing loss |
| Maximum gain | Lower than UP | Highest available in the Naída range |
| Battery life | Shorter (smaller battery) | Longer (larger battery) |
| Size | More compact | Slightly larger |
| Water/dust resistance | IP68 rated | IP68 rated |
| Connectivity | Bluetooth, myPhonak app | Bluetooth, myPhonak app |
Battery Size and Life: 13 vs 675
The most immediate physical difference between these two models is battery size.
- The Naída Lumity SP uses a size 13 battery, which keeps the device relatively compact and easier to handle for many users, especially those with moderate dexterity.
- The Naída Lumity UP uses a size 675 battery, which is physically larger. This extra battery capacity is exactly what allows the UP to push more power and typically deliver longer battery life between changes, which matters a lot for people who wear their hearing aids most of their waking hours.
If all-day battery life and maximum runtime are priorities, the UP has a clear edge. If a smaller, lighter device is more important to you, the SP is easier to live with day to day.
Power Output and Frequency Range
This is where the real functional difference lies.
The Naída Lumity SP is classified as a Super Power device, built for severe hearing loss. It delivers strong amplification but stops short of the maximum gain levels Phonak offers.
The Naída Lumity UP is an Ultra Power device — the most powerful hearing aid in Phonak's current BTE lineup. It is engineered for people with severe to profound hearing loss who need the highest possible gain and output to hear speech and everyday sounds clearly. If your audiogram shows profound loss across multiple frequencies, the UP is generally the safer clinical choice, since it has more headroom to grow with your hearing needs over time.
In short: SP covers severe loss comfortably, while UP is reserved for the most demanding, profound losses.
Shared Features: What SP and UP Have in Common
Despite the power difference, both models share the same core Lumity technology, including:
- SmartSpeech Technology for improved speech understanding in noisy and group settings
- AutoSense OS for automatic, real-time sound environment adjustments
- Bluetooth connectivity for direct streaming from iPhone and Android devices
- myPhonak app support for personalized control and remote adjustments
- IP68 water and dust resistance, making both models highly durable for daily wear
- Compatibility with Roger microphone technology for even better hearing in noisy or distant listening situations
Both models are also available across different technology (price) tiers — such as 90, 70, 50, and 30 — so the level of automatic processing and fine-tuning can be adjusted based on budget as well as hearing needs.

Who Should Choose the Naída Lumity SP?
The SP model is generally the better fit if you:
- Have severe (but not profound) hearing loss
- Prefer a smaller, more discreet BTE device
- Don't need the absolute maximum gain available
- Want a slightly more compact fit behind the ear
Who Should Choose the Naída Lumity UP?
The UP model is typically recommended if you:
- Have severe to profound hearing loss
- Need the highest available power and gain
- Prioritize longer battery life over device size
- Have struggled with previous hearing aids that couldn't provide enough amplification
Making the Final Decision
Choosing between the Naída Lumity SP and UP really comes down to the degree of hearing loss shown on your audiogram, combined with personal preferences around size, battery life, and daily wear comfort. Neither model is objectively "better" — they are built for different points on the hearing loss spectrum, and the right choice depends entirely on your individual hearing profile.
Because power hearing aids need to be properly fitted and programmed to your specific audiogram, it's worth speaking with a hearing care professional before you buy. If you'd like personalized guidance on whether the SP or UP is right for you, you can book a free consultation with one of our audiologists.
Frequently Asked Questions
Is the Phonak Naída Lumity UP louder than the SP? Yes. The UP (Ultra Power) offers a higher maximum gain than the SP (Super Power), making it suitable for more profound levels of hearing loss.
Do both models support Bluetooth streaming? Yes, both the SP and UP support Bluetooth connectivity for calls, music, and TV streaming through compatible smartphones and the myPhonak app.
Which battery lasts longer, size 13 or size 675? The size 675 battery used in the UP model generally lasts longer than the size 13 battery used in the SP, due to its larger capacity.
Can I upgrade from SP to UP later if my hearing loss changes? Hearing loss can progress over time, so it's a good idea to have your hearing reassessed periodically. If you eventually need more power than the SP provides, your audiologist can help you transition to the UP model or another suitable device - HearUpAustralia
Final Thoughts
Both the Phonak Naída Lumity SP and UP are excellent, durable, feature-rich power BTE hearing aids built on the same advanced Lumity platform. The real deciding factor is the severity of your hearing loss — SP for severe loss, UP for severe to profound loss — along with your personal preference for device size versus battery life.
