Behind the Ear

Signia Styletto hearing aids have a sleek appearance that looks more like consumer tech than a medical device.

7X is the top technology level available for the Styletto product. It comes with a complete set of sound processing features, including motion detection, speech focus, and 48 channels of customization for your audiologist to work with. If you regularly travel or spend time in groups, this top-end level will probably be worth the additional cost.

Signia Styletto is a prescription product and offers two options for care:

Pros πŸ‘
  • ‍Sleek product design
  • Bluetooth streaming enabled for iPhone and Android
  • Rechargeable
Cons πŸ‘Ž
  • ‍No onboard pushbuttons (requires app or remote control changes)
  • Signia Styletto is a premium product at a premium price that may be out of budget for some

As an audiologist, I am always on the lookout for the latest hearing aid technology. Recently I got to trial the Signia Styletto, an award-winning hearing aid from Signia, one of the leading hearing aid manufacturers.

In the clinic, I've fitted these devices on patients, but having firsthand experience gave me a new perspective.

I learned so much from wearing these devices and combined with my clinical experience, I'm excited to share more about this product to help you decide whether this product is right for you. In this article, I’ll provide an overview of this product and share my observations from using the devices.

About the Brand

‍Signia is one of the largest hearing aid manufacturers in the hearing industry, manufactured by WS Audiology. Previously, Signia operated under the Siemens name but was more recently acquired by Sivantos.

They offer a quality hearing aid technology portfolio with different form factors and charging options, which I'll explore later. Their products are known for their innovative design and split-processing AX technology to help with background noise.

The Styletto is their latest premium product which boasts a sleek design and top-of-the-line sound quality. Now that you know more about the brand, let's get into more specifics with the Signia Styletto.

Noteworthy Features

The Styletto has several noteworthy features that stand out from other models today. Aside from the sleek design, Signia's AX split processing is known for its smooth handling of background noise and motion sensor AI technology (pretty innovative, right?).

Signia's Own Voice Processing (aka, OVP) helps take the edge off of that uncomfortable sound quality of the user's own voice that many patients experience when adjusting to hearing aids. The convenient rechargeability options are some of the best on the market.

These hearing aids will easily last a full day, and the charging case holds four additional charges without needing to be plugged in.

Finally, you'll appreciate the hands-free calling options if you're an iPhone user. (Psst: Do you need a CROS hearing aid option? Signia's got that as well.)

Other Form Factors

‍The sound processing in the Styletto is available in three different form factors: behind-the-ear (BTE), traditional receiver-in-canal (RIC), and custom hearing aid options.

That's one of the great things about Signia technology. You'll have the same excellent processing technology available in different form factors.

Who is not best suited for the Styletto?

If you want a hearing aid with a disposable battery option or have dexterity concerns, there are better options than the Styletto. However, there will be other Signia options that can work here.

Personal Listening Notes And Wearing Observations

Okay so, let's get to the good stuff. My experience with Signia was positive overall. However, there are a few issues I experienced and you find more insights below.

The Fit

‍Overall, I found the Signia Styletto a comfortable fit in the ear. I wore the Styletto with a sleeve dome tip, which felt comfortable in my ear. The slim RIC design is also relatively lightweight, and I have no issues.

In the Office

When I wore the hearing aids into the office, I made several interesting observations. While doing an audiogram, I placed the headset over my hearing aids and was pleased that I didn't experience any feedback. (Note: My hearing aids were set to mild hearing loss, more significant hearing losses could produce feedback.) 

One drawback presented itself unexpectedly. In the middle of a conversation, my phone began ringing in my ears despite being set to silent mode. Later on, I found where to disable ringtones in my phone settings to prevent this from happening again.


I tried out a few different types of streaming, including podcasts and music. The sound quality for both was good. However, I did have some intermittency with my left hearing aid streaming cutting out. The Signia team suggested I place my cell phone in a front or back pocket toward the center of the body (rather than my right coat pocket).

This adjustment fixed the issue. One point that impressed me was the smooth transitions from streaming audio to external microphones. While in my car, I connected my phone to my GPS which spoke the directions through the hearing aids.

In between directions, the hearing aids returned to picking up sound from the car and road with smooth transitions.

Final Thoughts

Overall, I highly recommend Signia’s Styletto as an attractive option for those seeking a high-quality hearing aid solution that offers both comfort and convenience.

With its array of features, including background noise processing, motion sensor technology, Bluetooth compatibility, and streaming, it’s no wonder why this product has become so popular among patients worldwide.

So, if you're looking for a sleek hearing aid option, give the Signia Stylleto a try.

The breakdown

Signia Styletto hearing aids come at a comparable price to the other top-of-the-line products like Oticon More and ReSound One. So what makes this hearing aid different?

Styletto hearing aids have a unique design to the hearing health category. The sleek devices look more like tech products than medical devices and are a favorite among style-seeking customers. Styletto combines this fashion-forward design with all the features you would expect, like Bluetooth streaming, rechargeability, and clear speech in background noise.

The tech inside

Styletto hearing aids come with an AirPod-like charging case and Bluetooth streaming capabilities. The devices use motion detection to gather information about your surroundings as you move from one space to the next. The hearing aids automatically sense when you start walking or sit down and make intelligent decisions about where to focus. Styletto also gets top marks for the Signia Assistant feature in their app. The Signia assistant asks you simply worded questions about your current environment and preferences and adjusts your program based on your responses.

Getting up close

Styletto comes in 5 tech-forward colors, including all white, all black and two-toned with silver and rosegold accents.
