Here's my product review of this terrific, surprisingly affordable portable Bluetooth speaker.

OontZ Ultra — An Affordable, Waterproof Bluetooth Speaker That Sounds Fantastic! (1)
This compact, waterproof portable Bluetooth speaker is perfect for listening to music, podcasts, audiobooks and more, at home or on the road

Our Constant Companion at Home or On the Go

My husband and I love listening to music and audiobooks. Thanks to its compact size, impressive audio quality and IPX7 waterproof rating, the OontZ Ultra Bluetooth speaker is our constant companion whether we're in the house, on the deck, in the car, at the beach, by the lake or pool, or on vacation.

Note: The OontZ Ultra is also called the OontZ Angle 3 Ultra. To avoid confusion, I will refer to it from this point forward as the OontZ Ultra, to distinguish it from the slightly smaller, less expensive OontZ Angle 3 model.

Here's why we love it.

OontZ Ultra Waterproof Bluetooth Speaker —Key Features and Benefits

My husband and I love listening to music and audiobooks. Thanks to its compact size, impressive audio quality and IPX7 waterproof rating, the OontZ Ultra Bluetooth speaker is our constant companion whether we're in the house, on the deck, in the car, at the beach, by the lake or pool, or on vacation.

OontZ Ultra — An Affordable, Waterproof Bluetooth Speaker That Sounds Fantastic! (2)Here are some of the reasons we love ours and use it all the time.

Compact Size & Lightweight

The OontZ Ultra is just 6.5" long x 3" wide and weighs 1.03 lbs., so it's easy and convenient to take with you, whether from room to room or from your house to your deck, patio, backyard or car.

Don't let its small size and light weight fool you, though. This portable speaker packs a punch when it comes to audio quality!

Full, Rich Sound at All Volume Levels

Despite its compact size, the OontZ Ultra delivers the exceptional sound quality you would expect from a speaker designed and engineered in the USA by Cambridge SoundWorks.

Its 14+ watts of power and volume booster produce crystal-clear mid- and high-tones, while itstwo precision neodymium drivers and proprietary, downward-facing passive bass radiator deliver high-quality, full-range bass that's surprisingly rich for its size.

The sound reproduction is high fidelity, balanced and even from lows to highs. It never sounds muddy (too much bass) or tinny (too much treble).

  • Crisp Highs and Full, Rich Bass, Even at Low-to-Mid Volume. We prefer to listen to our music at moderate volume most of the time. Fortunately, this speaker doesn’t have to be cranked up high to sound good! You don’t sacrifice either clarity or bass when listening at low-to-moderate volumes.
  • No Tinniness or Distortion, Even When Cranked to the Maximum Volume.When we're listening to music or audiobooks in the car, we always use the OontZ Ultra for superior audio quality, rather than the car's built-in speaker. When we're on the highway or there's a lot of traffic, we often need to crank the volume on our songs, podcasts or audiobooks, and we love that the sound quality remains excellent even at full volume, with clear, crisp audiobook narrations and good bass with no distortion.

    IPX7 Waterproof Rating for Indoor-Outdoor Use

    This Bluetooth speaker is perfect for taking to the beach or the pool. No more worries about listening in the rain! The IPX7 rating means this speaker is fully waterproof and can be immersed in water up to 3 feet.

    Long Battery Life

    The OontZ Ultra Bluetooth speaker delivers a full day of listening pleasure on a single charge. The manufacturer claims that its rechargeable battery "provides up to 20 hours of playtime at 2/3 volume." So whether you're spending the day outdoors hiking, camping or at the pool or listening to music while you work, you never have to worry about running out of juice.

    Simple, Intuitive Controls With Large Buttons

    I love that I don't have to put my glasses on to read the controls of this portable Bluetooth speaker! The buttons are also large enough and easy to push without accidentally pressing the wrong one.

    I love how large the buttons and how intuitive the labels are on this portable speaker!

    Choice of Horizontal or Vertical Orientation

    This speaker can be placed either horizontally or vertically. While we usually use ours in a horizontal orientation, if you are using it on a desk or end table where space is at a premium, it's nice to be able to stand it on its end.

    Built-in Microphone

    You can take calls from any mobile phone without having to disconnect from the speaker, thanks to the built-in microphone that acts as a personal hands-free speakerphone.

    Excellent Bluetooth Connectivity and Superior Wireless Range

    The OontZ Ultra Bluetooth 5.0 speaker is a cinch to pair with our mobile phones, laptops, tablets and other devices, and the connection has been uniformly reliable. The manufacturer claims that with its "advanced antenna design and Bluetooth 5.0 technology, this speaker provides faster connection speeds," which my husband and I have found to be true.

    It also has an impressive wireless range up to 100 feet!

    Thanks to the built-in AUX-IN jack, you can also easily connect to non-Bluetooth devices with a 3.5mm Line-In cable (not included).

    Connect Two or More OontZ Ultra Bluetooth Speakers for Your Next Party

    While the OontZ Ultra has plenty of power and volume for my husband's and my needs, its maximum volume isn't loud enough for a party. Fortunately, you can connect between two and four OontZ Ultra speakers using the OontZ app and play your party music as loud as you wish in left and right stereo.

    This is also a great option if you want to play music in multiple rooms, given the speakers' 100-foot wireless range.

    Fantastic Sound Quality at an Affordable Price

    Although the list price of the OontZ Ultra Waterproof Bluetooth 5.0 Speaker is $49.99, at the time of this product review post's publication the price on Amazon was just $39.99. That's a terrific price for such a high-quality waterproof Bluetooth speaker.

    Even Smaller and Less Expensive OontZ Bluetooth Speaker Recommendations

    If you plan to bring your OontZ Ultra to the beach or on vacation, you might want to pay a bit more for the OontZ Ultra with Carry Case, which comes with a carrying case made of waterproof neoprene material with reinforced zippers and a built-in aluminum carabiner clip. The neoprene OontZ Ultra Carry Case can also be purchased separately.

    If you are looking for a great, versatile Bluetooth speaker with an even smaller footprint, you might want to consider one of the following options (there are also several other models):

    • The slightly smaller and less expensive OontZ Angle 3, which measures 5.5" long x 3" wide and has an IPX5 waterproof rating. The list price is $34.99, but at the time of this post's publication it was just $24.99 on Amazon.
    • The even smaller and less expensive OontZ Angle Solo, which we bought for my husband's parents. The adorable Solo also has an IPX5 waterproof rating but measures only 3.9" long x 2.8 inches wide and weighs less than 8 ounces! My in-laws love using it in their car during their 3-hour commutes to and from their lake house in Maine. The list price is $29.99, but at the time of this product review's publication, the price on Amazon was just $19.99!

    These Make Excellent, Affordable Gifts for Any Occasion

    The OontZ Ultra, OontZ Angle 3 and OontZ Angle Solo make terrific, affordable gifts for anyone on your list, for any gift-giving occasion. They're easy enough for a child to use, with sound quality that your favorite audiophile will appreciate. Think Father's Day gifts, graduation gifts, birthday gifts, or just-because gifts!
