Review: Amazing speaker, it sells itself! - I previously had a Studio 3 speaker, heard it playing in the Sprint store and was blown away, I had never heard a small bluetooth speaker so clear and full with a nice bit of bass to back it up. I had that speaker for about 6 years, had it playing at work all day long on top of my tool box in a shop environment, toted it home to use wherever I was working around the house. I estimated by the amount of hours it played at work every day during a normal work week, not counting all the time it played here at home, well over 10,000 hours of play time, before one of the woofers finally failed. The battery life was never impressive but it pretty much always stayed plugged in where I was using it, as it was directly stated it's more of a static speaker, it was never touted as a long play battery power bluetooth speaker. I know of almost a dozen people who have bought one after hearing mine at work and were blown away with the sound quality, and they all love theirs as well. So, naturally, when mine finally wore out, I replaced it with an Onyx 4. About the only thing different between the two, is the power up sound, and the passive radiator button color on the back. Otherwise they look identical. And my Onyx 4 sounds exactly like my Onyx 3. The added bonus is that with this new speaker, the battery life is good. There have been a few days I've set it on top of my box at 7AM and forgot to plug it in, and it was still playing when I went to put it back in my cabinet at the end of the day. For the price, this thing is amazing. I'm sure there are louder, harder hitting bass speakers out there, but not in this price range. Review: Best option, great price, amazing sound quality. - What a good speaker! For the price $145 dollars, it is a great deal. I use to buy Bose speakers but I decided to give Harman a chance. I have tried other HK speakers and amplifiers and I know this is a good company with good quality products. My personal opinion, this is a great deal and your best option. Before buy the HK, I got a desertcart Echo plus and the sound quality was really disappointing. So, I had two options: bose revolve or HK Onyx 4. I considered JBL Pulse, MegaBoom, and others but comparing price and functionality I found that HK is the best option. Some people complaint because it is too big and maybe for them it is not portable, but Im not looking for a speaker to go out, I was looking for the best sound at the best price. Additionally, I got portability. This new model has a 8 hour battery, the size is not too big but it is not small like a sonos or other speakers. I found that this model has a multi speaker option, so you can connect up to 4 speakers at the same time. In conclusion, this is a very very good bluetooth speaker, with a good battery (8 hours, enough for a party), quick connect option and multi speaker option. Very complete device! ## Features - Amplify your listening experience by wirelessly connecting more than 100 HK connect+ enabled speakers. - The rechargeable battery supports up to 8 hours of playtime - Stream music wirelessly via Bluetooth to enjoy room-filling sound. Connect up to 2 smart devices at the same time and take turns playing music. - Access Siri or Google now from the speaker with a simple button press.

Can’t Go Wrong! Buy It! *by T***S on August 30, 2018* This thing is fantastic and the price is ridiculously reasonable. I’m a Bose fanatic. I have 4 pairs of high end Bose headphones, two portable Bose speakers, Bose home theatre system, and Bose stereo in my car. I appreciate crisp, clear audio with sufficient bass that does not distort with elevated volume. I started using Echo devices as a network for whole-home audio - which works great by the way, as long as your willing to put an echo device in every room right next to the larger speaker since they do have to be plugged in using an aux cable in order to sync the playback - but the Bose portable speaker we were using in our bedroom was never quite in sync with all the other speakers. There was a slight delay from it which I attribute to a hardware issue with the speaker. Bought this to replace it on a whim since it was so cheap (especially compared with the $400 Bose speaker it would be potentially be taking the place of). So glad I gave it a chance. It is not quite as crisp as the Bose speakers, but it has good depth with plenty of midrange and more than enough bass to fill a bedroom with as much sound as you can take with zero distortion. ALSO - there is no lag from aux and the Bluetooth connection is seemless. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/45676474-harman-kardon-onyx-studio-4-wireless-bluetooth-speaker-black-new](https://www.desertcart.us/products/45676474-harman-kardon-onyx-studio-4-wireless-bluetooth-speaker-black-new) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-26*
