Took it to the beach, a little sand got in it, maybe moisture from the beach itself, whatever. I shower with it in the bathroom and my door closed (if that matters). It didn’t start sounding this bad until October. I’ve tried everything from resetting the speaker, restarting my phone, repairing my speaker to my phone, and updating my speaker.
When I tried the xtreme 4 after the charge 6, I was very disappointed because the xtreme 4 didn't feel louder and the bass wasn't much more punchy.
I actually think the Xtreme 4 is the best looking out of the Xtreme lineup. ... But I do own the Xtreme 4, and sound wise it is underwhelming. I expected a lot more, especially at its retail price. ... At $400 though, I really don’t see the value in either the Xtreme 4 or 5. ... Honestly, the Xtreme series makes sense at about 50% of retail. At full price, I think it’s a hard pass.
5 and it’s not even close.
I can say at least that the xtreme 5 was the right way, there is absolutely no advantajes of having 2 small woofers instead of a big one, really the size pf the xtreme 4 didn’t gave the advantages of stereo sound, and th 5 does have more bass but still its cristal clear sound, at least if you hive it a good eq, for the bb4, ive heard that it only distorted on the first firmware, not really now
I just bought the xtream 4 last month for 180 usd really good sound under 75% volume
I just got an xtreme 4 and it works well for me. ... Its loud enough and sounds good enough for me. Battery lasts long enough that I dont have to plug it in at all over 8-10 hours, which is nice, along with it being cheaper than the 5
I've got a charge 6 and Xtreme 4 and the Xtreme 4 is noticeably better in every way imo
I got the 4. Sold it.
They're a piece of s**t. I replaced a boom plus with this crap. ... I bought another boom plus and the 2 pluses are way better than extreme 4.
i am currently listening to music on a jbl flip 5 that i had before my xtreme 4 and the music sounds completely fine. nothing like what the video sounds like
I think for being in a factory you need as much power as possible. Probably lots of noise going on, etc… while the Charge is absolutely amazing, something in your use case is gonna need the power and loudness so I think it’s a no brainer to do an Xtreme 4 or if u can swing a great deal maybe a Boombox 3?
Yes The X5 is much better than the Xtreme 4 and Charge 6. ... I don’t think you’d be disappointed, and this is coming from a person who returned the X4 because I was not impressed with that at all compared to my Charge 6, as u mentioned.
I have both, and tldr, the charge 6 is a mini xtreme 4. It’s very filling, and has a good battery life. It supports lossless through type c, and for the price I got it for, very nice
✅ What Works
- Loud output well-suited to demanding environments requiring lots of volume
- Battery lasts 8-10 hours without needing a recharge, per owners
- Considered the best-looking model in the current Xtreme lineup by some owners
⚠️ Worth Knowing
- Sound quality is the most common complaint — called "underwhelming" for the price, with the dual-woofer design seen as inferior to a single larger driver
- Multiple owners report sound degrading over time after exposure to moisture or sand during normal use
- Widely seen as overpriced at full retail, with owners recommending the Xtreme 5 or Charge 6 instead
Owner sentiment on the Xtreme 4 is unanimously negative in this sample, 9 of 15 mentions critical, with sound quality the most frequent complaint (7 mentions). Several owners call the audio "underwhelming" for the price, arguing the dual smaller woofers underperform compared to a single larger driver, and some say it's a hard pass at full retail price around $400. A separate group of owners report sound quality degrading over time after normal exposure to moisture or sand. On the positive side, owners praise its loudness for demanding environments, long 8-10 hour battery life, and looks call it the best-looking speaker in the Xtreme lineup. Reasonable if you can catch it discounted well below list price and prioritize raw volume; skip it if refined sound quality per dollar is the priority — several owners suggest the Xtreme 5 or a Charge 6 instead.
