Slate VSX Headphones Review | Do We Even Need Studio Monitors Anymore?

The design is very unconventional. It combines a sense of science and technology with artistic beauty. However, the appearance is very recognizable, and the sound quality is also good.

It can be said that the product design and user experience give people a high-end perspective. Harman Kardon recently launched the ONYX STUDIO 7 Bluetooth speaker. What surprises will this product bring us?


ONYX STUDIO is a classic series from Harman Kardon. A total of 6 generations of products have been launched before, and the previous 5 and 6 generations are all seashell-shaped designs.

The top of the speaker is made as a handle, which looks like a handbag. And this time, the brand-new ONYX STUDIO 7 has undergone significant changes in its shape design, making it into a ring-like style, like a satellite circling the planet to make a 360° revolution, drawing a clear trajectory path.

The logo of Harman Kardon on the front of Harman Kardon onyx studio 7 is clear and intuitive. The ring shape allows users to use the top or bottom, the two handle areas, to pick it up with one hand.

The ring is made of anodized aluminum, which is very strong and will not have rust issues after long-time use.

The body is wrapped in high-grade fabric. The positions of the body and the ring are fixed, cannot be adjusted by displacement back and forth. At the same time, because the speaker adopts the shape of the ring design, it has two supporting points in different positions.

The supporting base is also designed with anti-slip rubber pads. Therefore, the onyx studio 7 is more stable when placed on the table or the ground.

The overall weight of the speaker is 3295g. Although it looks heavy, it is pretty easy to carry. It is not an exaggeration to say that it is a prominent portable Bluetooth speaker. There is no problem to take with it when you go out.

There are five buttons on the top area of Harman Kardon onyx studio 7. From left to right are the Bluetooth pairing button, volume down button, power on button, volume up button, and play button.

The play button also has the pause button function, and the volume up and down supports a long press to adjust the volume.

There is an indicator light below the button. When the speaker is turned on, a white indicator light will light up, and the unique sound effect of Harman Kardon will sound.

It is worth mentioning that the Bluetooth pairing method of Harman Kardon is different from many other speakers. It does not need to long-press the Bluetooth pairing button for the pairing operations. Instead, you can short press the Bluetooth pairing button, and wireless devices with Bluetooth functions such as mobile phones can search for it in the Bluetooth settings.

In addition, the pairing and shutdown sounds are also crisp and sweet. These sound effects are outstanding. Onyx Studio 7 supported Bluetooth protocol with version 4.2, and the audio is using SBC encoding format. But there are no higher encoding options such as APTX, AAC, and LDAC.

It’s a pity that Onyx studio 7 doesn’t support WiFi. It can only play music via Bluetooth or wired connection. Harman Kardon state the supported Bluetooth audio formats are A2DP 1.3 and AVRCP 1.6. Those are the most common SBC audio format.

Onyx studio7 does not support aptX and other high-quality Bluetooth sounding effects. Although the overall sound effect of the speaker is excellent, it will be better if it supports these Bluetooth formats.

There are three ports on the bottom of the back of the speaker. From left to right are the AUX port, the power port, and the maintenance port.

The speaker has a built-in 11.70Wh lithium-ion battery, which can play music continuously for 8 hours when fully charged. In addition, the Bluetooth speaker can be charged through the power interface.

Sound Performance

Harman Kardon onyx studio 7 has a built-in 120mm woofer and two 25mm tweeters. The rated output power is 50W, and the signal-to-noise ratio is greater than 80dB.

The bass is strong and powerful, especially when you put this Bluetooth speaker on the table and play the best rock music like “Boom”. You can feel that the table is also a regular shake along with the drum. You can feel its excellent bass effect very intuitively.

If Harman Kardon onyx studio 7 is used as a rhythm background music player for the party, it is also quite good.

In the mid-frequency vocal part, listen to the classic old song “Upside Down”, a male and female chorus. Again, the timbre of both male and female voices is quite mellow and clear.

For the high-frequency female vocal part, I chose “Endless Tears” as the test song. The tone reproduce of the high-pitched link is also very well done. There is no screaming due to excessive pitch and no glitch.

The human voice is also quite clear, and it also brings an immersive sound field. Different types of songs such as rock and female voices are very suitable for listening to. If one more ONYX STUDIO 7 is added, a powerful stereo system can be set up.

Users with higher requirements in terms of sound quality can also enjoy a better music experience through an AUX connection.

In the past, many Bluetooth speakers only supported wireless connection to one mobile device, while ONYX STUDIO 7 can connect two Bluetooth devices simultaneously.

In this way, when you and your friends are at the party, everyone can use their mobiles to play songs without reconnecting, which is very convenient. Of course, there must be a first-come-first-served song to play songs. Harman Kardon onyx studio 7 Bluetooth speaker will not have the problem of crosstalk when two mobile devices are playing simultaneously.


In general, Harman Kardon onyx studio 7 Bluetooth speaker still has unique and innovative craftsmanship in its shape design, and the minimalist style is just right. In addition, the sound quality also performed well.

It is not only a practical portable Bluetooth speaker but also a piece of art worth watching carefully and slowly. No matter where it is placed in a warm and comfortable home, there will be no obvious sense of violation. You can feel the elegant life outdoors. It is definitely a wise decision that you go to learn more about this novel artwork.

Harman Kardon Onyx Studio 7 Review

Harman Kardon’s latest portable Bluetooth speaker, the Onyx Studio 7, looks like it’s been shot out of a time machine. At $479.95, it lacks the features we now commonly see in speakers for half the price (or less). In terms of sound, the Onyx Studio 7 delivers a powerful bass depth that will appeal to those looking for thunder, but not at the cost of nearly $500. There’s no equalizer to customize the sound to taste, Bluetooth codec support is outdated, and the speaker lacks water resistance. You can end up with much better performance for that price – or even for a lot less.

If Onyx Studio 6 is like a designer handbag, Onyx Studio 7 takes things in a completely different direction. The fabric and metallic materials remain, but this speaker is more like a tribute to the planet Saturn. Measuring 12 by 10.6 by 6.3 inches and weighing 7.3 pounds, available with black, blue, or white fabric grilles, the Onyx Studio 7 has a rounded body that appears to be floating inside its ring handle. The grip is also the stand that the speaker rests on to stand on flat surfaces in an upright position. It’s an interesting design that won’t be for everyone, but it’s nice to see the company pushing the envelope a bit on portable speakers – it really doesn’t look like any speaker we’ve tested in a while.

Also, it’s worth noting that yes, it’s a portable speaker with a battery and a built-in handle, but it’s heavy, so it can be carried more between rooms rather than in scatter mode. Meaning “in a bag” or “to take it on a hike”. Unlike the Onyx Studio 6, the Studio 7 is not waterproof and does not have an IP (Ingress Protection) rating at all, making it a poor choice for most outdoor scenarios.

Under the grill, two 1″ tweeters and one 4.8″ woofer provide a total of 50 watts and provide a frequency response of 50 Hz to 20 kHz. At the top of the grill are buttons for controlling Bluetooth, power, playback, and volume up/down. The play button can be double-clicked to skip a track forward, but there’s no way to rewind a track, which is annoying.

A recessed panel on the rear panel houses a connector for the included power adapter, a 3.5mm aux input, and a USB-C port for service. There is no aux input cable included, which is disappointing for the price.

Onyx Studio 7 is compatible with Bluetooth 4. 2, which is a bit dated and unfortunately only supports the SBC Bluetooth codec – it does not play AAC or AptX codecs. There’s also no equalizer companion app, so you can’t customize the sound signature. At the very least, the speaker can connect to another Onyx Studio 7 wirelessly to form a pair.

Harman Kardon estimates a battery life of around eight hours, but your results will vary by volume level.

Onyx Studio 7 sonic performance

On tracks with intense sub-bass, such as The Knife’s “Silent Shout”, the Onyx Studio 7 makes a serious rumble. At maximum volume levels, DSP (digital signal processing) kicks in to prevent distortion, but this doesn’t seem to deplete the low frequencies too much. At slightly lower volume levels, the bass is powerful and well balanced with the higher frequencies in the mix.

Bill Callahan’s “Drover”, a track with much less deep bass in the mix, gives us a better idea of ​​the Onyx Studio 7’s overall sonic signature. The drums on this track sound like, well, like thunder, just like the sub-bass on the previous track. If you have an Onyx Studio 7 on a resonating surface, it will vibrate a lot – and this is a track that really doesn’t cause the subwoofer vibration that we associate with, say, electronic music. Callahan’s baritone vocals take on a pleasing richness of lows and mids combined with crisp highs and mids, while the acoustic kicks and percussive hits in the upper register have just enough high-mids and highs to keep them bright and clear. It’s a heavily boosted and sculpted mix with a lot of added bass.

Watch us test the speakers

On Jay-Z and Kanye West’s “No Church in the Wild”, the bass drum loop gets high enough in the middle to attack to keep its punchy power, but the added bass depth also fills the loop with a rumble that it usually doesn’t have. . The sub-bass synth hits that punctuate the beat turn out to be too deep for the drivers to reach out and grab them – we get some of their power, but not the full subwoofer hum you might hope for. Instead, you’ve added bass power at slightly higher frequencies, creating intense kick sounds. The vocals on this track are delivered clean and clear without much hiss, but sometimes they can sound like they’re fighting for space, with added bass thunder.

Orchestral tracks, like the opening scene from the John Adams ballet. Gospel of the Other Mary , as well as jazz tracks, as a rule, sound quite natural in Onyx Studio 7. Boosting the low frequencies on these recordings doesn’t knock out much. The low frequencies do take a big step forward, but not enough to upset the balance and outshine other higher register instruments.

The Wrong Speaker Now

The Harman Kardon Onyx Studio 7 has powerful and capable drivers, but it just doesn’t offer an experience to match its $480 price tag. It doesn’t play high quality Bluetooth codecs, it doesn’t have any extra features, and its portability is limited by its weight and lack of water resistance. Simply put, this column seems outdated. For much less, the $350 JBL Xtreme3 ​​and the $250 Sony SRS-XB43 are two portable options that outperform the Onyx Studio 7 on several levels. If you want a design element, consider the $500 Bang & Olufsen Beolit ​​20, which is a lot more fun overall.

Harman Kardon Onyx Studio 7 speaker system review: now in Belarus!


In Belarus, the Onyx Studio 7 speaker system appeared quite recently. i-Store is one of the few stores where you can buy a new product. And at a nice price. What does Harman Kardon offer for 559 BYN?

On the occasion of the opening of our new showroom, which took place on August 19 in Galleria Minsk, the i-Store team, together with partners, decided to raffle valuable gifts among the first 50 customers. The winner of the thematic quiz got the heroine of today’s review – the Harman Kardon Onyx Studio 7 speaker system.

The proud owner of a Harman Kardon dispenser is pictured in the center.

What do we know about Harman Kardon?

Harman Kardon is a world famous audio brand founded by Sydney Harman and Bernard Kardon. The joint path of two enthusiastic scientists began in 1953, and a year later their first development became a real breakthrough. It was the world’s first compact Hi-Fi FM tuner.

Then, one by one, products appeared on the market, which for 65 years have allowed Harman Kardon to remain the market leader. The brand’s team includes highly qualified experts in the field of design and acoustics. But let’s not be unfounded and give a few facts that confirm the high status of the brand.

  • The iconic Harman Kardon Soundsticks is part of the permanent collection of the Museum of Modern Art in New York.
  • HARMAN, which owns not only the Harman Kardon brand, but also JBL, AKG, Infinity and others, is one of the main suppliers of audio equipment for major automotive brands.

The company has about 30,000 employees in North and South America, Europe and Asia. In March 2017, HARMAN became part of Samsung Electronics. But the Harman Kardon brand still relies on modern elegant design, impeccable sound quality and functionality.

Cosmic design

Harman Kardon’s new Onyx Studio 7 speaker system appears to have been inspired by onyx, a mineral that is a type of agate. The portable speaker itself is very similar to a small spaceship – black, blue and light gray. Many see it as a miniature of the planet – thanks to the aluminum carrying handle, which in its shape resembles the ring of Saturn. By the way, the handle serves as a stand at the same time.

The round speaker cabinet seems to float in the air. And the Onyx Studio 7 is as beautiful to look at as it is to touch: it’s finished with premium acoustic fabric. At the top of the speaker are convenient buttons that fit perfectly into the overall concept: switch, Bluetooth pairing, volume control. And on the back you can find an AUX port for connecting other audio sources, a power input and USB-C for hardware upgrades. In addition, you can pair two copies for stereo sound with Wireless Dual Sound technology.

Perhaps, Onyx Studio 7 received the most unusual design that we have seen recently. However, the photos speak for themselves.

Surround sound

The first sound of Onyx Studio 7 is incomparable – so juicy and dynamic! That’s because inside this small spaceship is hidden a whole system of three speakers – one low-frequency and two high-frequency. Their sound profile emphasizes the bass, which makes the sound expressive and voluminous.

At the same time, the developers managed to achieve an amazing balance: medium and high frequencies are not muffled, but pleasantly “glide” over heavier sounds. What is important: this effect is equally heard both at a quiet volume and “to the fullest”.

Powerful Battery

Onyx Studio 7 is portable. This means that the column can work without being connected to the network. The battery capacity is quite large – 3250 mAh. This is enough to listen to music continuously for up to 8 hours.

True, the listening time can be affected by the volume level. A sound volume of 80 dB will be more than enough for a cozy family evening at home, as well as for a noisy outdoor party. It will take about 5 hours to fully recharge the charge.

Who is it for?

The weight of the device determines how it will be used. Throwing in a backpack and constantly carrying almost 3.3 kg on your shoulders is not a particularly tempting idea. And the dimensions are not small: 268.0×302.5×159.5 mm. Therefore, it is not difficult to conclude that Onyx Studio 7 is a desktop speaker system. It was created in order to enjoy pleasant high-quality sound at home or, for example, in the office.

However, if you have the desire and the opportunity to take it with you somewhere on vacation, who will forbid you to do this? The sound power of 50 watts is enough to make a lot of noise! The only thing to consider: Onyx Studio 7, although it is made of high-quality materials, still does not have water protection.
