    Great Portable SpeakerI recently purchased my second Onyx speaker. The sound and control are amazing. I’ve tried others and they simply don’t measure up. Worth the price!

    The 4 was so good. I did not hesitate when I saw the 6 on sale. I love these speakers.If you are not familiar with these speakers. Please take a listen. Clear clean sound and full of bass. The battery lasts a good whole day at the park. OK…. guaranteed 6 or more hours. And the sound is large.

    Superb sound from a slightly heavier portable Bluetooth speakerI would not say that the speaker is super portable as it is slightly heavy/bulky compared to the much smaller versions of other brands out there. But the handle at the top makes it not an issue. If you want flawless sound that is portable (I got about 10 hours of playtime on one charge with the volume at half maximum), I do not see (hear) how you can do better if you’re willing to spend the extra money for quality.Playing the first song out of this speaker just floored me. The bass was thumping and trebles were very crisp. “Beats” the sound quality of other similar offerings. Of course, this is due to the size of this unit, but it is very much worth the extra weight and circular footprint.The weather proofing is also holding up to its promises, as I had it out in the snow with no audible or visible degradation. Just be aware, that other than the handle, the speaker is wrapped in a tight cloth-like mesh which could get torn. I did not have that experience but then I take care of my equipment as much as possible.Finally, the sound is directional (not 360° like some of the other H & K offerings) but that is not anything different from other portables.One caveat about Bluetooth connectivity: it can only handle up to two different devices connecting to it. If you wanna add a third Bluetooth device that would stream to it, you need to disconnect one of the first two in the settings of those particular devices. This is not unusual for these types of devices but since I learned about it, trying to stream from my iPad after I had already connected my iPhone and another device, and the speaker wouldn’t connect. Forgetting one of the two earlier devices in the Bluetooth settings solved the problem.

    Not much difference between HK Onyx models 5 & 6, but still a pretty good speaker.This is a little lengthy but it’s an honest review.I purchased this speaker after listening to how awesome my friends HK Onyx 5 sound. I thought getting the Onyx 6 would be just a step up from the 5 but was very surprised that it was not. I bang my music loud, and don’t get me wrong this one does get loud, but the HK Onyx 5 was the winner in the both vocals and bass. The description of this product (HK Onyx 6) stated that this speaker was bass heavy and that is what sold me. I could tell that they tried to bring the bass, However, I believe you still get more bass from the HK Onyx 5.There is one small annoyance that I think lies within the product itself and is the reason why I contacted the seller and asked amazon for a replacement. The sound lowers or skips when switching between applications on the device that the speaker is connected to, in my case my cell phone. I would have pandora or spotify play my music and at the same time I would surf the web, look at my amazon app or whatever the case, and each time I would exit/switch out from one app to another the sound would get lower or it would skip then it would return back to full sound. This is an extremely minor problem as the sound would return and the music would continue to play normally, but it does get a little irritating when you are vibin’, but thats just my opinion.Now for trying to reach the seller (Electronics Club): not possible. That’s it. No contact number and no reply to message sent.Even with the differences between the two models and the minor annoyances of the lowering or skipping of the music, the real reason I give this product a three out of five is because I could not reach the seller, I instead utilized amazon who tried to help me troubleshoot my problem and offered me the replacement. Amazon is a great company and always comes in with the solution. 10 stars to Amazon.I’m going to keep the speaker because it is not a horrible product but if you already have the HK Onyx 5 just stick with it or skip the 6 and move on to the the 7 or 8. The all black speaker is nice on the eyes and the port cover in the back maybe useful in some situations but that just may be the extent of the differences between the two models 🤷🏾‍♀️. Im just saying.

    Got Bass? HELL YA!After some research, I was looking for a USB speaker with some bottom (deep bass for those unfamiliar with musician terms, lol). Anyway, this unit did NOT disappoint! I was willing to pay a little extra because I knew it’d cost more but it was well worth it. What also helped is that my son already had a Harman Kardon product so I was familiar with the sound quality. I want to buy another so that I can pair them somehow. Buy it. You won’t regret it.

    very good speakersthe highs are pretty crisp but the bass on these are superb. one speaker alone can fill up a room pretty well with sound. highly recommended speakers.
