Harman Kardon Onyx Studio 3 Wireless Bluetooth Speaker (Refurbished)

High-quality sound resounds from this convenient and portable wireless speaker, which boasts a long-lasting battery and built-in speakerphone for taking hands-free phone calls.

Wireless Connection, Stunning Sound

This portable speaker connects wirelessly to your Bluetooth-enabled smartphone or tablet, making it easy to pump out your favorite playlists. Spitting out up to 30 watts (on battery) or 60 watts (while plugged in), the speaker has dual woofers and tweeters that ensure every booming low note and uber-high trill will sound as if you were there when it hatched from the songbird’s egg.

Make and Take Calls

A built-in mic with noise and echo cancellation allows the speaker to double as a speakerphone. So if a call comes in or you want everyone in the room to scream “happy birthday” for grandma, the Onyx Studio 3 has you covered.

Long-Lasting Battery

With a powerful rechargeable battery, the speaker can play continuously for up to five hours in one charge. That’s long enough to clean your whole house twice, make some coffee, check your email, and decide what to wear.

About Harman Kardon

At the start, engineer Sidney Harman and his boss, Bernard Kardon, were innovators in public-address sound systems. But the company they worked for wasn’t as interested in broadening its horizons and crafting sound systems for homes. So they created their own company, being among the first to offer a simplified receiver for radio signals with high-fidelity reproduction. That model, the Festival D1000, was a huge hit with music lovers, and in the decades since the company hasn’t looked back. Today, it produces an entire range of home audio equipment, including home-theater systems, sound bars, headphones, and Bluetooth speakers.

In the description it says "connects wirelessly to your Bluetooth-enabled smartphone", but how is that connection made? The instructions that came with the speaker include maybe every language imaginable but say very little in the long run. I have connected my smartphone via aux port and the speaker does have a big sound. I will enjoy it even if I never learn to connect via blutooth, but if somebody reading this knows how to connect I'd sure appreciate a tip!

For a portable speaker I love it. It's clear . 4 stars only because I thought it would get a little louder.
