If you’re looking for a great wireless speaker with some great bass added to it, the Onyx speaker is it. You’ll be able to fill a room with quality sound and bass.

You’ll be able to amplify your sound experience, thanks to its excellent technology within the speaker. Other than great quality sounds, it’s very mobile as well and makes it great if you’re ever on the road or traveling.

The great thing about the Onyx Studio 4 is that you’ll be able to listen to this for eight hours. And at the same time, Studio 4 is wireless.

You’ll also enjoy the features this speaker brings as well such as Siri or Google Now. Other than great the great features the Studio 4 provides, is the design, which is excellent, elegant and very minimal which is great.

If you’re looking for high performance and a simplistic speaker, the Harman Kardon Onyx Studio 4 is it. So, let’s jump into the review for the Onyx Studio 4.

The Design

If you’re looking for something simple, yet aesthetic, the Onyx Studio 4 is it. Thanks to its fabric grill, you’ll have a great looking modern speaker in your living space. The back is made up of quality plastic with a rubberized silicone texture to it.

Bottom line is the design looks great and should add some aesthetics into your room.

The speaker weighs around four pounds, and you should be able to move the Studio 4 with ease. If you need to move it to a friends house, it’ll be easy as well, thanks to its grips; you’ll be able to have a good handle on this speaker.

The speaker also has two stands so that way you’ll be able to set up your speaker upright on a table or any flat surface, which is excellent. However, you won’t be able to adjust or remove the sands on the speaker.

The speaker, however, is not waterproof nor is water resistant. And also is not drop resistant as well.

The mic is great; you’ll be able to use the built-in mic with ease, regardless if there are loud noises present in the area.

Sound Quality

The sound quality is excellent and should fill a medium sized room with great sounds. And you shouldn’t have a problem filling out a full space room.

Compared to other high-end speakers such as the Sony XB40 or the JBL Xtreme, you’ll have higher quality sounds and with a harder bass to it. So that way you’ll be able to enjoy your games and multimedia.

When watching a movie or just merely gaming, you’ll have high-quality bass that will resonate and bump within your living space. The quality isn’t distorted when you up the volume, instead you’ll get higher quality sounds and bass.

In my opinion, I love having great bass in my speakers because I’ll be able to jam out epically with my favorite tunes.

However, in comparison to the JBL and Sony, you’ll get more heavy quality bass that’ll deliver.


The features are excellent. With the speakers being Bluetooth, you’ll be able to connect wirelessly. You’ll be able to pair your mobile device or any device to the Studio 4 by a push of a button, which is located in the bottom left.

The great thing about the Harman speaker is that you’ll be able to connect more than a hundred plus speakers all at the same time, which is excellent if you’re throwing out a party or just changing your living space environment.

Battery Life

The Onyx Studio 4 operates with a 3,000mAh battery, which can last you up to eight hours.

It also has a 3.5 mm port connection and power port. With the wireless feature, you’ll be able to use the Onyx Studio 4 for around eight hours. However, users claim they get around five to six hours.

Even when on fifty percent volume, you’ll be able to get around six hours of battery life, which is pretty decent for a quality speaker in my opinion.

In Conclusion

With the Onyx Studio 4, you’ll be able to jam with your favorite tunes and game for hours upon hours. You’ll be able to get high-quality sounds and bass that will go boom when you blast this speaker up to full gear.

Compared to other high-end speakers, the Studio 4 bumps harder, thanks to its powerful bass and high quality sounds that you’ll be able to get out from this incredible speaker.

The bottom line is that Studio 4 has quality sounds, balanced and has powerful bass. The style’s aesthetically simple, you’ll also have Bluetooth capabilities.

So if you’re willing to invest in an excellent wireless Bluetooth speaker, the Onyx Studio 4 is it.
