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.

I purchased this item because I know the quality. However, when I received the item, there was no powering cord or charger. I could only listen for maybe 20 minutes before it powered out. Personally the product is fine but the seller needs to check his items prior to sending. Now I have to find a power cord to charge up the speaker and this is such an inconvenience>>>>>>>

Great speakers. The sound quality and intensity is absolutely amazing. I ended up getting a two more as presents for nephews. The battery in the second one does not last as long though, but it is a refurbished speaker after all.

Not too friendly to pair. It requires some research of how to connect 2 together. No instruction whatsoever delivered. Excellent sound for the price !!
