It Deserves More the 5 Stars!

I wish I could give this one more stars! This is one of the best sounding and visually interesting Bluetooth speakers I have ever run across. I always get compliments from other people not just about how cool it looks but especially how it manages to fill the entire room with lush rich music. No wonder this speaker has been so popular. I ended buying a couple more for friends and family. If you are considering buying one of these, just do it!
I would recommend this to a friend!

Disappointing

I just bought one this week Harman Kardon Onyx Studio 8
and fully charged it over night. When I started using it but it keeps turning off after 1 hr of playing music but claims 8hrs? Very disappointing I love how this speaker sounds but hate the battery life it has

Response from harmankardon.nlBy Customer Support, August 14, 2026
We appreciate your feedback! The battery life on your HK Onyx Studio 8 speaker depends on volume, bass levels, and audio content. High volume and bass can significantly reduce playtime. To check battery health, fully charge your device, play music at low volume without bass boost, and see if it matches the advertised playtime. If it's significantly less, the battery might be deteriorating. Should you determine that the battery is losing its capacity. Contact us at support.jb.com for further assistance.

Love the onyx studio 8. This is my second one. Wanted to be able to pair them. It sounds so good though that one of my son's talked me into giving it to him for his birthday.

Fabulous Speaker

This is my second Studio speaker and I absolutely love them. The sound is rich and the size makes it easy to tuck away in a corner, even behind a drapery panel. Set up is effortless, just unbox and bluetooth connect and enjoy. The first speaker I purchased was for the facial room in my spa (Glow Lab Skin Atelier) and it is perfect, and the 2nd speaker was purchased for the the spray tanning area. The ambiance these have brought into the spa created the high end luxury sound I was after. Also, when my sister heard how wonderful the sound was she jumped online too and ordered one.
I would recommend this to a friend!
