Harman Kardon Onyx Studio 8, Portable stereo Bluetooth speaker

One of the best sounding %26 efficient portable speakers I've encountered. Takes up slightly more room than some, but the sound is worth the slightly large larger size. Battery life is not quite as long as some smaller options. Works well connected to AC outlet, which is the only charging option as well. No USB. Highly recommended for anyone wanting or needing quality sound from a portable speaker.

The device is quite large and heavy for a Bluetooth box - at least compared to the portable bluetooth boxes on the market. However, it is probably more intended for home use and less for outdoors. The handle makes it easy to carry from room to room. The box is quickly connected to the mobile device and the functions can be executed via a few buttons. These are not necessarily self-explanatory - e.g. the earpiece button is also used to skip tracks - but are well explained in a quick guide. The sound is much better compared to smaller (and also cheaper) bluetooth speakers, especially the bass is heard more. The round shape also contributes to the surround sound. Visually, I like the box well and fits well into many interior styles.

The mere fact that we have three of these speakers says it all. I'm presently in the process of buying one more . “our family and friends love them”

a great speaker with a good sound. it can easily be carried in the hand. I think it's great that there are different colors. the speaker doesn't take up much space. In general the quality of the device is wonderful.

This is my second HK Onyx. I have had the first one for over a decade and it still works. Just some reverberation with the base sometimes. I love the color and handle on the new one!

My last purchase of this Harman Kardon speaker brings me up to my 8th. I am in my 70's and past my prime of being a music/techie. However I entered a store and was stopped in my tracks over the incredible sound of the establishments background music. I asked a young man what I was hearing and he pointed to a single speaker. This Harmon Kardon Onyx 8. I purchased 2 on the spot despite buying speakers was the last thought on my mind. I have sice purchased 6 more for gifts as others have the same reaction I didon that fateful day of hearing this speaker for the first time. I decided to try on of the Onyx 9 since it is a newer version. The 9 is a huge disappointment in comparison to the 8.

We've had the first iteration of this speaker for nearly a decade. The sound quality is still superb after 10 years of use, it still holds charge for a good couple of hours, it pairs easily with new devices. This speaker is a really solid investment in your long term aural joy.

I have now tested this speaker for over a month and Iam really happy with it. At first, the design of the speaker was a bit too futuristic to me. But in the meantime I really like this design and in the right environment it really looks cool. After testing speakers with Alexa and even wlan features, this speaker is really „simple“. It has an Aux Channel and Bluetooth. But it doesn't need more. The Bluetooth connectivity is really good and any device did connect to the speaker. The only thing I miss is the possibility to switch the speaker on when I connect a device. At the moment I have to switch the device on with hand. But now the most important thing - the sound. The sound is really fantastic. It is a full sound, with good bass, but not too loud that it overrides the middle tones. It can get really loud and even than the sound is really good and did not overtune. I bought the speaker for my living room, but with the power to take the speaker with me and play music for 8 hours it really is a dealbreaker. This is not a speaker to take with you every day, but for special occasions I love to have this speaker now.

The box arrived well packaged to me. The connection via Bluetooth was quick and easy, but that should be the standard by now. The design is classic and timeless, but fits almost every modern interior. Practical is also the carrying handle with which you can easily carry the music box to other rooms. Now to the most important the sound is great, the bass is nice and powerful and the battery is very durable. Was last on a move with friends the box ran there the whole day through. From the dimensions amazes the rich sound in the small box. Also the adaptive sound depending on the room is well done. I can give here quite clearly 5 stars, the device does what it should and exceeds my expectations by far in terms of sound and design.

Sound was excellent. Esthetics, also excellent. Doesn't look like your typical Bluetooth speaker. The bad. I ordered two to specifically run in stereo. The process to pair them together is ridiculously problematic. Once I did finally get them paired, one speaker had a charging error of some type. Nothing I tried could alleviate the issue. Very disappointing. These big names could learn a lot from Soundcore on user friendliness
