History of Bluetooth Hearing Aids

This may come as a surprise to many of you, but Bluetooth hearing aids have been around for almost a decade. The world’s first bluetooth enabled hearing aid was introduced by Starkey Hearing Technologies in July of 2005. The device, known as “ELI,” was capable of connecting to Bluetooth-enabled mobile phones (and other Bluetooth audio devices) a full two years before the first-generation iPhone.

If you’ve been paying any attention over the past few months, you may have noticed a lot of press for the world’s first “made for iPhone” hearing aids. But, hang on. The ELI was capable of streaming audio from the iPhone years ago.

Flash forward to 2014

Starkey is in the game again. In April, they released the Starkey Halo, one of the world’s first “made for iPhone” hearing aids; with no intermediary devices necessary. Taking advantage of Bluetooth low energy, and a “proprietary high quality audio streaming protocol” developed by Apple, the Halo is able to stream audio from iPhone 4S and up, and many other Apple devices. Note: If you don’t own or plan to purchase one of the later iPhone models, the more affordable iPod Touch is a good alternative (as long as it is running iOS 7 or later). At last count there were seven hearing aids (from seven different companies) released with the new made for iPhone technology. For this post, I want to focus on two of the most popular hearing aids available, the Resond LiNX and (you guessed it) Starkey Halo. While many blog posts have discussed the two devices, there has been little in the way of comprehensive comparison. I hope this will serve as the definitive comparison guide. Begin LiNX versus Halo.

What’s all the fuss about?

The ELI, like many of its successors, wasn’t  actually a hearing aid at all. As Apple Insider correctly points out, now is the first time hearing aids have been able to connect directly to the iPhone, without the need for some type of intermediary device, or “streamer.” The ELI, was just that; an intermediary device that collected sound from a Bluetooth-enabled phone and sent it to the hearing aids. If you take a close look at the image above, you can see a boxy device attached to the bottom of the hearing aid. That is the ELI. Note: The ELI was able to send sound to the user’s hearing aid by way of Direct Audio Input (DAI) or telecoil induction, two much older, less sophisticated technologies. So, why did hearing aid companies opt to connect hearing aids to phones through these cumbersome intermediary devices? Was it just a ploy to upsell customers with extra gadgets? The reason this approach was taken is simple. It was the only technologically feasible option at the time. Until very recently, Bluetooth radios were large and power-hungry. If hearing aid companies had produced real Bluetooth hearing aids in the mid 2000s they would have been huge, and would have required AA batteries – not an easy sell. But over time, Bluetooth radios have become smaller, and require less power than ever. The lofty goal of real Bluetooth hearing aids has now become a reality.

Resound LiNX Versus Starkey Halo

If vanity is a concern, then you should know that the Resond LiNX is significantly slimmer than the Starkey Halo.  This is mostly due to the fact that the LiNX takes a smaller 312 battery, which is half the thickness of the 13 battery that the Halo takes.  However, a bigger battery does mean longer battery life.  And with the amount of wireless processing going on, a bigger battery may be worth it.  Both manufactures have recommended extending the battery of the iPhone through purchasing a case with an extra battery in it (such as the Mophie).

Also, the Resound LiNX has an ear-level control in the form of a push button, whereas the Starkey Halo has no ear-level controls available on their product.  If you require the ability to control the volume on your hearing aid, even when your iPhone is dead, then you may want to consider the Resound product.

Lastly, Resound has just extended the range of styles that the LiNX come in.  You can get the LiNX in both a receiver-in-the-ear, as well as a behind-the-ear (BTE) hearing aid styles.  Starkey Halo only comes in a receiver-in-the-ear style.  I am happy to announce that Resound just launched a special new super-power BTE version of LiNX called the Enzo.  I won’t go into the details of the Enzo on this post, but keep watching for further reviews.

Linx Versus Halo Size Comparison

App Features

Starkey dominates in this area.  As a hearing aid company, they have had more apps out for longer than any other manufacturer.  Starkey’s app for the Halo is named “TruLink,” and Resound’s app for the LiNX is named, “Resound Smart.”  Both apps have your basic volume control and program changing features.  However, Starkey’s interface for volume control weaves in an optional simultaneous tone control feature.  This unique screen that crosses volume and tone adjustments in one move of the finger is being branded by Starkey as the “SoundSpace.”  Granted, the volume control is limited to +/- 8dB, which is fairly conservative; however it is easy to save sound preferences from the SoundSpace into individualized programs, and even tag them to specific locations on the map.  Marking maps with sound preferences for automatic retrieval when within a few hundred feet of that location, is called “Geo-tagging.”  This is a hot new term in the hearing aid technology world, but both manufacturers do have this feature.

It should be noted that the Resound Smart App also has a bass-treble control, but it much more linear in design – like going into an equalizer on your favorite sound device, but only finding two channel to adjust.  The same can be said about the personal microphone feature from each manufacturer.

The personal microphone feature turns the iPhone into a microphone.  Anything coming through the iPhone microphone will be picked up and put directly through the hearing aids.  It’s like the Extendable Ears in Harry Potter and The Order of the Phoenix.  Starkey has the personal microphone feature build into their app.  You can even record and save recordings in this screen.  The Resound app does not have the personal microphone feature.  The rational for this is that it is built straight into the iPhone (although I wouldn’t have figured this out without being told).  Apple has built its own basic hearing aid control screen into all of its products under the accessibility settings tab. Any Made-for-Apple hearing aid can use this screen. To get there quickly, the short cut is to press the button on the iPhone three times, or “triple click.” Not only are hearing aid volume and manual programs accessible from this screen, but the “live listen,” feature turns the iPhone into a microphone that directly streams to the hearing aids. This personal microphone is an advantage, as the iPhone can then be strategically placed.

Both Starkey and Resound apps also has a fairly accurate hearing aid locator. If the hearing aid is not in the near vicinity, then the map will show you where it last had contact with the hearing aids; or where it was last in range of the hearing aids. Once near the hearing aids, then the visual equivalent to a metal detector will guide further searching to within a few feet.

Linx Versus Halo Feature Comparison Infographic

UPDATE:

The LiNX2 hearing aid family has been released. For more up-to-date product features for the LiNX, please see our new LiNX2 hearing aid page, and see our comments in the discussion below!

  • We have been informed that the Resound 77 and 88 LiNX hearing aid models (as well as the new power aid, ENZO), are equipped with Telecoils.

  • Christopher Scot Frink

    That is an EXCELLENT Infographic, which I plan to use for my consultations when comparing products.

    One thing that you didn’t cover, which is durability. We have been fitting both products since March/April (different release dates) and found that the ReSound has a very flimsy case. Every patient we have fit with the Linx has had issues with the case tearing. It happens when they open the battery door, which is very easy to hyperextend. I get the impression that ReSound knows this (but has denied it when we complained) because they ship us an extra (replacement?) case with every order. We’ve never had this done with any product ordered in the 35 years we’ve been in business, but for whatever reason ReSound thinks it’s needed. Maybe because the cases tear so easily?

    My complaint is supported by their website promoting Linx (http://www.gnresound.com/hearing-aids/hearing-aid-products/ReSound%20LiNX#!prettyPhoto) If you go to the bottom, you’ll see it promote a

    “New easy-to-change housing” (pasted directly from their website).

    How we’re handling this is by warning patients against hyperextending the battery doors–something we haven’t had to do with the Stakey Halo.

    BTW: Linx is also a lot more expensive than Halo, at least to us.

    • Rhys Taylor

      Hi Christopher, good comment, thanks. I agree, durability is an important factor. Other than case issues, have either of these had moisture issues despite their nano-coating?

      • Christopher Scot Frink

        We haven’t noticed anything specific regarding problems with moisture.

    • Jacquelyn Dunne

      Hello. My name is Jacquelyn and I work for National Data Research. We are looking for people who wear either the Starkey Halo, Beltone First or GN Resound Linx hearing aids for a paid medical research study. The study would involve a 30 minute telephone interview and pays $75. If interested, or know somebody that is please call me at 847-410-0404, ext. 1053.

  • Ian Cooper

    Hi
    Thanks for the comparison, very interesting.
    I was interested in Rhys question about moisture, and the reply given.
    My current aids Phonak Audeo, sold to me even though I am very active and want to be able to run and cycle with them, keeping breaking down due to sweat ingression, (audiologist was made aware that I sweat a lot whilst exercising).
    So, in your opinion, may this be a problem with either of these aids?
    Fully understand your opinion would not constitute a guarentee.
    Thanks
    Ian

    • Ian, Do you know which generation of Phonak Audeo you have? Also can you pinpoint which part of the hearing aids are susceptible?

      • Ian Cooper

        My Audeo’s are the pre spice range I believe.
        They were purchased Oct 12. Left returned to Phonak via provider 3 times, right 4 times now, (may be 2 and 3 times, too many anyway).
        Ingress I would say is via battery area.
        I get the dying battery sound. Drying box helps.
        Eventually, permanent air con whirring type noise, or battery last less than a min type noise, or echo type noise.
        Have tried head band, very expensive crash helmet for extra ventilation.
        My provider has now at last agreed to change my prescription, not sure what they may have in mind yet, hence the questioning on here of the ReSound/Starkey.
        Many thanks
        Ian

        • Take a look inside your battery door. Do you see flexible rubber lining inside, to seal out moisture? I’m pretty sure the answer will be no. Some of the more recent Phonak hearing aids from the Quest and Venture lines are IP rated ( http://en.wikipedia.org/wiki/IP_Code ) … meaning you can confidently assume a level of moisture and dust protection. I would recommend that you familiarize yourself with code, and ask your audiologist to discuss the IP Ratings of the devices they recommend to you. To the best of my knowledge the Siemens Aquaris has the highest IP rating of any device on the market, but there may be some other devices with similar ratings. There will be many factors to consider (aside from moisture protection), but be sure to consider a selection of devices that at least meet your needs on this…

          • Ian Cooper

            Hi
            Many thanks for the useful information here, really appreciated.
            You are correct, no rubber lining in my current aids.
            I am still waiting for my providers customer service department to update the audiologist to the fact that they have agreed to replace my aids.
            I am currently information gathering, reading loads.
            My current provider, (Boots Hearing Centre, UK), deals mainly with Phonak, Starkey, Unitron and Widex, although the audiologist has said they can get any manufacturers aids.
            I assume the 4 quoted must give the biggest discounts.
            They also apparently have a, “tie-in”, in Phonak, (or the other way round, not sure which).
            Anyway, thanks again for your help.
            Regards
            Ian

    What would your review be of the Linx2 vs. Halo?

    • Jen,

      Sorry about the delay in getting back to you. There have been a few significant changes in the new line of LiNX2 hearing aids. We recently began adding the LiNX2 to our product directory, and while we haven’t finished adding all of the custom in-the-ear devices (which weren’t previously available in the LiNX line), we have added all of the behind-the-ear options, including the new form-factor, which takes a size 13 battery. This is an important update in the product line as it means you can finally get a small behind-the-ear LiNX with sufficient battery power to handle all of the “smart” features, like direct audio streaming from mobile devices, etc.

      There have been a few significant changes to the hearing aid technology and a couple changes on the “Smart App” as well, including a new app for Android users (Samsung Galaxy S5 users only). I have attempted to cover some of these differences in my new LiNX listing, so please refer to that for upgrades to the actual hearing aid technology.

      https://www.hearingtracker.com/hearing-aids/resound-linx2-9-rie-62-ls962-drw

      The new “Smart App” features a “Sound Enhancer” which adds new fine-tuning controls. “Comfort in noise” allows you to adjust the noise reduction of your hearing aids. Remember you can only reduce the volume of “steady-state” noises; noises that change in volume and pitch are harder to remove. “Speech focus” allows you to change the directional focus of your hearing aids … Imagine a beam of hearing in front of you, where you hear sounds inside the beam better than sounds outside the beam; the Sound Enhancer gives you hypothetical control over the width of the beam. The last new feature is called “Comfort in wind. ” With this you may reduce the sound of wind noise if you’re stuck outside on a windy day. Increasing wind noise reduction may have an effect on your ability to hear speech as the amplification of the hearing aids will reduce.

    Michelle,

    I have just purchased (30 days) a pair of Starkey Z-series hearing aids but since I have profound hearing loss I’ve not been satisfied with the results. My provider is telling me that Starkey has now come out with Halo for Android. She may be able to swap my Z-series with the Starkey/Halo aids which means I would have to upgrade my Samsung Galaxy S-3 to the Galaxy S-5 or S-6 and buy whatever else I needed to make it all work. I’ve seen some stuff on the Internet saying the Galaxy S-5 is a better product than the S-6 for Halo. My question is whether Starkey/Halo will work the Samsung Galaxy S-6 as well as the S-5?

    Your web site has provided some important valuable information for those of us who are considering this and I want to thank you for your apparent impartial comparison between the Resound LiINK and the Starkey Halo. We need this kind of information. The cost of hearing aids is beyond reasonable and a mistake can be devastating!
