ZVOX – SOUNDBASE.350 Soundbar Review

Choosing a sound bar is one of the best decisions I have made in life. But since I bought a budget sound bar, I’ve missed the boomy bass I get when watching my favorite action movies.

Getting a separate sub is one of my options, but with the limited space I have, I’ve been thinking to just enjoy the movies without the bass I love.

Then it came to my mind to look for sound bars with a built-in subwoofer. Perhaps, it could somehow satisfy my thirst for bass. So I started going through sound bars with subs and listed down my observations, which I am sharing here.

Who is It for?​

If we face the same problem of loving all frequencies but is spatially incapacitated to purchase an external subwoofer, the one with a built-in sub may be the answer to our prayers.

If, however, you are expecting a boomier low frequency, one that you can feel, an external sub may be the one you are looking for.

So, before deciding to buy a sound bar like this, consider:

  1. Your audio preferences. Do you want just an enhancement of your TV speakers? If yes, then this will work.​
  2. Your room size. Do you want more from your speakers but have limited space? Then one-box speaker is what fits your requirements.

The ZVOX Soundbase 350

Just like other ZVOX sound bars and soundbases, the 350 is made of a durable fiberboard, has a simplistic design, has sound enhancing and leveling technologies, and so on. It is about two feet long, with three speakers and a subwoofer inside.

It is placed directly underneath your TV, and it can hold up to 42” screen size.

The ZVOX Soundbase 350 may be one of your options should you wish to enjoy all three frequencies from your speakers without the need to purchase separate components. And without compromising the sound quality.

But be warned: its surround sound option is virtual. If you want the theater-like surround sound, get a home theater system. Or if you have a bigger TV screen, you may opt to get another sound bar or place the soundbase in the shelf instead.​


  • The sound is loud and clear.
  • Has built-in subwoofer.
  • Has AccuVoice to enhance dialogues.
  • Has digital, analog, and Bluetooth connections.
  • Can be used with the TV’s remote control.


  • Not really for surround sound watching.
  • Cannot decode DTS.
  • Bluetooth functionality acts up sometimes.
  • The remote is somehow limited to about 5 feet distance.

ZVOX Soundbase 350 Features & Benefits

1./ Ease of Use

The ZVOX company is dedicated to making things simple. Hence, they design their products to reflect this goal. The ZVOX Soundbase 350 does just that with its single box design, one-page manual, and minimalist controls on the soundbase itself.

However, due to minimalism also, this soundbase is only 24” long, which means it can support only a limited TV size and weight. If you have bigger TVs, then this should be placed in a cabinet and not as the TV’s base.

2./ AccuVoice Technology

ZVOX’s AccuVoice Technology ensures that you can understand the dialogues in the movies more than the sound effects. However, if the movie you are watching has badly mixed audio or the actors in the movies mumble, AccuVoice may not be able to help.

3./ Output Leveling

This feature levels the sounds between TV shows and the commercials, so it won’t shock you when an ad suddenly pops up.

4./ Bluetooth aptX

To lessen the latency in Bluetooth streaming, aptX codec is installed. Many find this helpful especially in music streaming, but some complain that it does not work as expected with other devices.

5./ Built-in Subwoofer

The built-in sub is a plus factor for anyone who is looking for complete frequency without the need to occupy much space in the room. The bass works perfectly well, but of course, an internal sub will still have its own limitations.

6./ Overall Sound

With the technologies integrated into the soundbase such as the AccuVoice, apTX, Output Leveling, and others, this speaker is definitely a big step up from your TV’s speakers. However, even though this soundbase is multi-awarded, note that it has limitations especially in the giving you a surround sound experience.

ZVOX Soundbase 350 Reviews

The ZVOX Soundbase 350 received mixed reviews regarding its features, especially the Bluetooth function. Some complain that it doesn’t play music continuously while others claim that it takes a long time to pair with some devices.

However, these reviews are unanimous in saying that this soundbase can deliver a high-quality sound, better than TV's built-in speakers, which is for me the most important function a soundbase or soundbar should have.

ZVOX Soundbase 350 Awards

Because of the great sound it can deliver, this soundbase has received multiple awards from different companies.

Some of which are CNET’s Best Product of the Year, About.com’s Home Theater Product of the Year, E-Gear’s Editor Choice Award, Home Theater’s Rave Award, Sound & Vision’s Reviewer’s Choice Award, PC World’s Must Have Gadget, and Stereophile’s Recommended Component.​

ZVOX Soundbase 350 Alternatives

1./ Pyle 300 Watt Bluetooth Soundbar (PSBV200BT)

Pyle 300 Watt Bluetooth Soundbar

If you are looking for a cheaper alternative, try this one from Pyle. At the time of writing, it is priced below $150, and it has mainly positive reviews.

Just like the ZVOX 350, this is a Bluetooth soundbar and built-in sub, but unlike the ZVOX, this has 5.1 channels. It also has SD card and USB slot with FM radio tuner. However, this soundbar doesn’t have the optical port.

In terms of performance, Pyle is praised for its clear and crisp sound, much like the ZVOX 350. However, it is heavily critiqued for its durability. Some report theirs stopped working within months after purchase.

But if you just want to try a soundbar for the first time, this will be a good starting point for you.​

2./ Samsung HW-J250 80 Watt 2.2 Channel Audio Soundbar

Samsung HW-J250 80 Watt 2.2 Channel Audio Soundbar

Another cheaper alternative is this entry from Samsung. Just like ZVOX, it has built-in subs, not just one but two although even these two still cannot make your windows shake.

It also has various connectivity options such as Bluetooth, optical and aux, and even USB.

It is also an enhancement to the TV’s speakers, but it lacks other audio enhancements the ZVOX has such as the dialogue enhancer and the auto leveling of sounds, especially when transitioning from a show to a commercial. But if you are just after getting better speakers than the built-in on your TV, this fits the bill.​

​3./ AccuVoice TV Speaker AV200 With Hearing Aid Technology

AccuVoice TV Speaker AV200 With Hearing Aid Technology

If enhancing the TV’s built-in speakers is all your after, you may be able to get by with a product from the same company, ZVOX.

The AccuVoice TV speaker is ideal for enhancing dialogues in your favorite movies. However, note that its specialization is on the dialogues and not other stuff. But it has all the connections the 350 has except the Bluetooth connectivity.

Also, another missing feature in this speaker is the built-in subwoofer. So if bass matters a lot, then this product may not be for you.​

The Bottom Line

Because flat TVs have started getting rid of appropriate sound systems, an external speaker has become necessary. But for us with limited space, it may be a cause of concern.

Speakers in one box such as ZVOX soundbase 350 is ideal for us who are into better audio experience without the need for multiple and separate components. All the three drivers and subwoofer is encased in one shelf, giving us more free space for our other stuff.

However, because all the drivers are housed in one cabinet, your bass experience may not be as shaky as you want it to be.

But if that doesn’t matter, this product may be the one you are looking for. See what other reviewers are saying about it here. If you want more options, check out my previous article.
