Harman Kardon Onyx Studio 4 Wireless Bluetooth Speaker Black (New Model, 100

Great room filling sound. Speaker likes to be pushed to higher volume levels. Excels in lower bass notes. Noticed if I carried my phone around Bluetooth signal gets lost. Would have loved additional treble and bass on speaker or tone control.

Sound quality is great, although battery life is not the best. Would still recommend it though

Sounds the best I ever heard must keep plugged in battery only lasted 2 hours

The only thing I dont like is the battery life is not very long. But I like my music loud, always. So theres that.. But if you leave it plugged in, its amazing. You can feel the base and the sound is crisp and clear. If my ears could hear 4k that how I would explain the sound. This speaker was worth every penny I spent on it

Probably my favorite portable speaker of all time.

Comes with everything you need sounds amazing

I bought it to stereo pairing two studio 4. The sound quality of studio 4 is better balanced than studio 6. However, with the AUX connection, the beginning of the song is cut every time it changes to the next song. which has been improved in studio 6.

I tried five different bluetooth speakers in the $100-$160 price range and this speaker won me over hands down! I was looking to replace a $195 Bose Soundlink Revolve that wore out after only 3 years, and I would say that the Onyx Studio 4 has as much bass or more that the Bose. The mid-range and treble the Onyx produces is clear and powerful. I am hearing more sound in the upper ranges than I ever heard with the Bose. The Onyx Studio 4 is more than enough speaker for a 300sf room. Pairing was easy with my iPhone and I even love the sound the Onyx makes when it powers on and off.

Loved it, full sound asome gift!!
