Two Weeks With ZVOX’s VB20 VoiceBud

An elderly gentleman wearing a pair of high tech digital hearing aids accompanied his wife to a kennel club meeting at my home a few years ago. He had little interest in the dog doings upstairs so I invited him downstairs into my listening room. It allowed me to conduct an experiment of sorts. Did he like music? Yes. Had he ever heard or seen a big high performance audio rig? No, he hadn’t. Would he like to hear some music on it? Yes he would: jazz or classical. I obliged, curious to find out what exactly he heard listening through digital hearing aids to a high-resolution audio system. The look on his face told me he was hearing plenty.

When the jazz track ended (I’d played him the first side of The Bill Evans Trio’s Sunday at the Village Vanguard from the original Analogue Productions 45rpm set) I asked him to describe what he’d heard.

The first thing he said was “Each instrument is separated out in three-dimensional space. I can follow each one individually. The sound isn’t coming from the speakers.” Then he remarked that the instruments sounded “real” especially the cymbal shimmer.

So, despite grabbing the sound through a pair of microphones and then through a system that I assume digitizes, amplifies and then converts back to analog for in-ear playback, his costly system communicated the high performance audio experience. It gave me hope for what I hoped for me would be way into the distant future.

Some time in November ZVOX emailed an advertisement for its reasonably priced “VoiceBud”, which even at the regular price of $299 each was far less than the cost of the ones the visitor had worn, but for the holiday season the price was even lower so I hatched another plan: my 89 year old mother-in-law was having trouble hearing the television or us for that matter but she wasn’t eager to visit an audiologist or pay thousands of dollars. What if I could get her to slip on these affordable hearing devices and she liked what she heard? Everyone’s quality of life would improve. Plus I was curious to hear what I would hear wearing a set of these dual-microphone devices designed to enhance voices in a variety of circumstances, but particularly in noisy restaurant type environments where many older people have difficulties (but where I’m still fine). I was curious to hear how accurate these VoiceBuds were compared to my actual hearing!

So right around Thanksgiving I emailed ZVOX’s Tom Hannaher and asked if he’d like me to review a pair of VoiceBuds and try them on my mother-in-law and write about that experience as well. He liked the idea, as did my mother-in-law who already was benefitting from the ZVOX sound bar I’d bought her that’s designed to improve television sound vocal intelligibility and does.

Shortly thereafter a pair of VoiceBuds arrived and for the first time in my life I was about to experience a hearing aid in my ears. Listen, somewhere down the road, and not in the too distant future I’ll surely need these, just as I didn’t need glasses until 42, so, at the risk of destroying my career, why not listen now? This product is not designed to restore normal hearing to seriously hearing-impaired people but rather to help people with the usual age related hearing loss that affects the midrange and makes difficult understanding conversations in crowded, noisy spaces like restaurants and movie and television dialogue.

VoiceBud Tech

Simply stated, the VoiceBud is a dual microphone, directional hearing device that uses microprocessor control to greatly attenuate sounds coming from behind the wearer while boosting in the vocal region, sounds coming from in front. In three of the device’s four listening modes, the level of behind-the-wearer sounds is approximately halved. The four modes are: “normal”, “noisy-room”, “automobile” and “outdoors”. Choosing among them tailors the built-in multi-channel compression and noise reduction system designed to attenuate loud, distracting sounds, while 12 bands of frequency shaping emphasizes voices in the unit’s 200Hz-5.7kHz frequency response range.

The specs make you realize this is an audio system: in addition to the aforementioned frequency response the Peak output level is 113dB, “Full on” HFA (a hearing device standard) gain is 89dB (±2db), while Gain is 29dB and input level is 60dB.

The device itself, which fits behind the ear is 1” x 0.3”. In other words it’s 1/3 of an inch wide and not exactly “tiny” but for the most part, especially if you have hair, it’s hidden. All that’s visible is a short section of a small diameter plastic tube attached to the VoiceBud that forms an ‘earhook’ on top and runs into the ear where at the other end is one of a generous choice of soft elastomer insert “domes”. In addition to various sized domes, you can choice among sealed and open ones.

A Bluetooth enabled IOS/Android app controls left and right units either separately or simultaneously. Using the app you can control volume, bass and treble (!), choose among the four “modes”, check battery life (approximately four days on a single 312 per device) and get app use help. You can also make a few adjustments directly on the VoiceBud but the app is the way to go.

We Have Insertion!

My hearing is still pretty good, though not what it was 30 years ago. I have some tinnitus that shows up as a constant low level background noise that does affect somewhat midrange hearing and thus dialog intelligibility. It’s a problem that bothers a large enough percentage of the population, exacerbated by stupidly high concert SPLs and irresponsible headphone use, so much so that many A/V receivers include a special setting that boosts the midband region where voices live—and no doubt the age drops annually of the population needing this enhancement. Further exacerbating this problem is the current mumbly/whispery style of acting and the lousy state of soundtrack sound. More movies today sound like crap than don’t!

I did all of my listening using the open inserts as opposed to the closed ones that are better for people with serious hearing loss. The key to listening satisfaction with the VoiceBuds is to adjust them as you would a subwoofer in your audio system. The idea is to not hear them but to be able to hear their absence when you turn them off.

Once correctly adjusted so that I could not hear the VoiceBuds but could notice their absence, I found late night TV listening seriously enhanced. Dialog intelligibility was subtly but critically improved to the point where I could easily understand the conversation with the TV volume so low my wife could remain sleep.

The real test of course was downstairs listening to music. Again the VoiceBuds were adjusted to not be audible with only their absence audible—like a well set up subwoofer. I wondered how music would sound having my ears partially blocked with the open inserts and then subtly amplified in the midrange. I was surprised to find that the Voicebuds did not negatively impact my audio system’s vivid three-dimensional spatial presentation, nor did it sound as if my ear canals were partially blocked by the inserts—but that was only after painstaking adjustment of both the overall amplification level and the app’s bass and treble controls.

Once my ear/brain system got used to the VoiceBud’s presence, they disappeared both aurally and physically (I forgot they were in my ears), leaving only a slight enhancement to very low-level information. For instance, the entirety of “Prelude a la nuit”, the first movement of Ravel’s “Rapsodie Espagnole”, which opens The Reiner Sound (RCA LSC-2183) is very quiet—never rising above mezzo-forte. As another older audio reviewer who shall remain unnamed once mentioned, the solution to not hearing well these super-quiet passages is simply to turn up the volume and then if need be, turn it back down when the levels increase. I found I could leave the volume way down at the beginning of the piece where the levels begin just about the noise floor and hear everything clearly yet when the musical levels increased I did not have to turn down the volume.

When I listened again without the VoiceBuds, the beginning of the piece was somewhat more difficult to hear into my noise floor, but the overall sound was of course, more natural and organic. In other words the sound does take a hit when amplified but when everything’s set correctly you are only aware of it when you remove the amplification. I quickly understood why that double hearing aid visitor had such an enjoyable afternoon listening to music.

For now of course I will do without the VoiceBuds when listening to music and of course when reviewing audio gear but at some point in the future when I stop doing that and limit myself to music reviews, who knows? And by then this technology will improve.

More importantly, once I’d installed the VoiceBuds into my hesitant mother-in-law’s ears and she heard what she’d been missing (which was most of our conversations with her that she’d cover by nodding in agreement) she did not want to ever again be without the VoiceBuds so we bought for her the review pair and she’s living happily with them in her ears all day every day since.


If you have an elderly parent or grandparent who wears glasses without embarrassment but for some reason refuses to admit to hearing loss (or if you are having trouble hearing conversations in noisy restaurants or understanding movie dialog), ZVOX’s VoiceBuds are a cost effective solution that doesn’t require a visit to an audiologist. Get a set, pop them in your hesitant parent or grandparent’s ears and if your experience is like mine, watch their faces light up as they discover what they’ve been missing.

I'm having problems now listening to the TV and also find it difficult having a conversation with ambient sound in the background.
No real probs with the HiFi but I feel this could be an improvement.

Working several years as an audiologist assistant I can tell you that unless one has severe hearing loss and truly needs custom BTE hearing aids w custom molds most of what people pay 3k-6k per pair is nothing short of a damn rip off. These OTC units are expected to get "better and better" and the rip off centers the likes of Miracle Ear/Siemens product (who aren't audiologists but commissioned hearing aid dispensers) are worried. I say F em'! Get your ears professionally cleaned at an ENT and then get yourself one of these cheap but good products and be done with it. This is very good news for the consumer who's on a limited budget with "slight to moderate" hearing loss. I've seen 1st hand how the commission only salespeople at Miracle Ear have used scare tactics to manipulate the elderly into spending thousands of dollars every 3 years..

Happy and Healthy New Year To All!

I'm very happy to see an article/review on a hearing aid. I've had tinnitus for years and it does affect my enjoyment of listening to music. I recently went to the ENT and my hearing test gets worse every year with many drops in the high frequencies. It was suggested I get hearing aids but I'm just not ready for that yet. But it did make me think of wearing hearing aids to get more enjoyment out of listening to music. The doc also told me hearing aids will cancel out the tinnitus, he described tinnitus being caused just like a phantom lim. When you lose hearing your brain tries to make up for the lost frequencies and tinnitus is the result... how pleasant.

So again I was really excited to see this article pop up with Michael reviewing a hearing aid. I'm optimistic that the future will bring many advances so we don't get ripped off and better sound will be had for all. Thanks for the review and Happy New Year!

"The doc also told me hearing aids will cancel out the tinnitus"
SOMETIMES they can help but not alway. I know of people who were helped as well as those who weren't. If your audiologist allows you to try before making the plunge I'd say go for it, that is if your tinnitus is very bothersome. For some it can be extremely debilitating causing disability, depression, anxiety and even suicide. Some also have tinnitus masking sounds (white noise, etc.) imbedded into the hearing aid that can work as a masking device and even retrain ones brain to learn to ignore the phantom noise. Again, it works for some but not all.

There's also an amazing website as well as a FREE application ( for some of the nicest relaxing tones available (for free).

I to am very pleased to see this hearing device being plugged on here. It's all about music which enriches all of out lives and sound. Wearing ear plugs I strongly advice to all of my fellow music lovers who read Rabbi Mikey's blog..

Happy and Healthy New Year To All!

For anyone with T. I highly recommend checking Julian Cowan Hill on youtube; he has helped me a lot to get better.

This is mostly a brain/nervous system issue and not necessarily an ear issue as commonly diagnosed; although it can certainly be triggered by damaged ear hair cells it can have many causes. Mine was caused by stress for example.

Anyways the main point Julian makes is that regardless of how you got it you can get better ; )

“Further exacerbating this problem is the current mumbly/whispery style of acting and the lousy state of soundtrack sound. More movies today sound like crap than don’t!”

This is a very real problem! Understanding dialogue in a 1939 Hitchcock is never an issue (for me or my teenage sons) but with anything from today, we need to turn on subtitles. It has a lot to do with music in every scene and almost a compulsion to use the theater surround system to its fullest, whether the scene justifies music / effects or not.

I often wonder if it is because the subject matter of many movies today are so dumbed down that only a sequence of 10 millisecond-at-a-time jumpshots and an overwhelming soundtrack can compensate for the thematic vacuum and that even those who make smart dialog movies feel the need to give the audience what they are used to in the other 95% of the cases?

Most of us are motivated to get hearing aids to better understand speech. However, optimizing speech tends to make music less perfect. Thus, some manufacturers include a setting for music listening and it is, in my experience, very worthwhile. Switching to music mode may also necessitate adjusting the volume. Probably.

If you ever get back to this, get some samples from Widex or Bernaphon. I'm sure that other companies offer this feature also. This would be the basis of a great article and might help many enthusiasts.

If you are hearing impaired be very careful about NSAID use especially naproxen sodium. My left hearing was damaged beyond repair due to water in the ear and the pressure changes from a multi hop flight twelve years ago. I have been protecting my right ear ever since. I did notice aspirin caused an increase in tinnitus. In June I had shoulder pain that was preventing me from sleeping. I took two naproxen sodium tablets for two days, that allowed me to sleep but I woke up on the third day deaf. The ear recovered over the next few weeks aided by a high dose of steroids from the ear doctor. I needed a hearing aid for my right ear to converse at work. I have the most expensive available but it imparts a mechanical tone to voices that I dislike. I prefer to listen to TV with my HD580s. I have not listened to my HiFi since June but last weekend tried the HD580s on the Beatles mono CDs, not bad and no mechanical sounds.
P.S. I believe my original hearing damage was due to multiple ear infections from windsurfing in dirty old Buzzards Bay back in the 80s and 90s.

Devices like these will greatly advance and become more audiophile friendly (and smaller) as time goes on. Bose is actually working on such as we speak. Aging baby boomers will be big business in this area. Also, I predict equalizers will make a major comeback for aging audiophiles. Combine one of the hearing devices which is customizable by an app along with an outboard EQ hooked to your gear, one can maintain a great listening experience as they age.

When I was in my late 50's I had my hearing checked and found severe loss in high frequencies. As an audiophile since my 20's I approached buying hearing aids like a new piece of gear. I tried on all available brands including in home listening, while working with multiple audiologists. What I found was the vast majority of hearing aids were helpful for voices and in loud environments but awful for serious music listening -- with the exception of the top of line behind the ear Siemens that has two dedicated music settings. Now my high frequency hearing extends to bring back most of what I lost. Highly recommended. Suggest everyone over 50 have regular hearing tests.

I just noticed this article and was excited to read it, Mike. I was wondering whether advancing age was impacting your ability to review equipment and music. Now, I know. I am 70 years old and experienced a sudden loss of high frequencies three years ago. It has been a frustrating three years but I have recently found a way to enjoy music in my home again. Yes...using hearing aids. I won't say that it is good as my hearing was ten years or even five years ago. But the impact and depth are there and I am good for hours. My tastes have changed from rock to jazz and classical. Complex musical passages tend to produce a bit of harshness; especially massed strings, woodwinds, and horns. I have also found that a really good headphone amp and closed-back over the ear headphones, worn over the hearing aids, give the best results.
I am hoping to see more about the subject of hearing loss and restoration in your future writings. It is something that will happen to most of us at some point.
