(function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } So I bought this Ankuka karaoke machine back in 2019. For something that would probably go for under $200 these days if they still made it, it had a good run, scratched my karaoke itch, and died a very unceremonious death this year. So began my hunt for the “perfect” karaoke machine/BT speaker. And seriously, I tried them all. I would order, wait in anticipation, get excited when they arrived, try them out, send them back. I am currently still waiting for refunds on some of them. Anyway, I swear, many of these machines are exactly the same, made by the same people in the same factories, and shipped out under different names. They look the same, they all have their flashy lights, monster and gibberish sounds, no real EQ to speak of, and way overuse the “echo”function as if that’s some kind of good thing. But most of they all sound the same, with little to no difference between them, and none of them were better than the old die hard Ankuka, at least when it was new. I even tried a few of the “all in one” systems, with built-in rechargeable, microphones, built-in tablets, and these crazy claims have incredible wattage and power, none of which were true. All those were great in concept and appearance, but definitely not in the execution, with latency/delay issues, subpar tablets that didn’t connect right or stay connected and microphones that were just - blah. If you really have nothing better to do, you can read separate reviews on all those items. But I won’t name names because it’s not worth it. Bottom line - the JBL Party Box 310 was kinda my last try at this. I figured if I didn’t like it, I’d either keep the flawed but livable all in one that came on the same day, reorder the first cheap copycat of the JBL PB 310 I sent back, or hang up my jock so to speak and not have a home karaoke system/BT speaker at all. I ain’t getting any younger, after all. But then this thing shows up and as listed in the title, it absolutely CRANKS! My house literally shook when I turned it on, connected to my phone (very quickly by the way) and started playing some sample songs. I was worried a little bit as while the volume was super loud, it sounded a little “muddy”, even without the bass boost. Adjusting the EQ settings on my phone helped a little but I was still not overtly thrilled. And then I was like “oh yeah - there’s an app for that!” (Don’t sue me, Apple!). So I dowloaded that, synced it to the device, did the update (really, already?) and with the app’s EQ feature, it sounds much better - more crisp. Oh and did I mention that it CRANKS? Man is this thing loud. Now I did but this thing primarily for karaoke. Unfortunately, mics don’t come with the JBL PB 310 or any of the PB’s, I believe, so I had to order those separately and they just got here today. I don’t consider them to be world class, professional mics but they do the trick well enough, there’s no latency/delay that I could tell, and since JBL makes them, I knew there’d be no issues being compatible with the device, which I had to connect to my iPad for karaoke use as though I can do that with my phone, it’s nice to have the words much larger. I did a few tunes and once again, something was bugging me - the mics were way loud - almost too loud and I realized I spent $99 on mics with no volume control. That couldn’t be right. Luckily it wasn’t as the JBL PB 310 does have mic volume control - but it’s on the back of the speaker, not on the mics themselves. I talked about that in my review of the mics themselves. I don’t see it as a speaker issue, but it is a JBL issue. Maybe someday they’ll make mics with the controls on the mics so I don’t have to spend time crewing around f with the back of the speaker. But at least the issue was resolved. The unit also has a hole in the bottom so it can be mounted. It’s covered so I didn’t think there was one but the cover popped right off and I was like “YES” as I did buy a speaker stand that went with the “all in one” systems I tried. But I wasn’t sure that the JBL PB 310 had one as it’s not mentioned anywhere in the description that I could tell and not shown in any photos. Not worth docking a star for or anything, because it’s definitely a good thing, but its presence would be good to feature so people know in advance. So to sum it up, finally I think I’ve found my “perfect” home karaoke machine and BT speaker! It’s portable, seems to be on good rollers, has a handle, has an app to adjust the EQ and fun party lights (among other features), clearly works well with the JBL mics I got, you can mount it which actually brings the sound and volume to a whole new level - oh and did I mention this thing CRANKS??? It’s not cheap, and JBL offers some others that are presumably even better, louder and crisper (given their costs), but good things usually aren’t - and this one works for me. So with the price and the quality thus far, I’ll really hope this will last a good long time (I mean heck the now discontinued Ankuka I had lasted 5 years), and I won’t be shlepping this one back to the UPS store anytime soon - hopefully not at all. Absolutely 5 stars and I’d highly recommend to anyone looking to up their karaoke game or just looking for a good, loud, powerful, BT speaker! Happy shopping!

I was a DJ and soundman for many many years in the 80's and 90's. I WISH I had a speaker this compact with this kind of sound back then. I own two of these, and usually set them up TWS in stereo. My wife is an elementary teacher and her school had a "trunk or treat". So I set up the rear our Expedition all dressed up like the face of a cat with the mouth and teeth being the opening. I put a party box at each corner of the SUV and used our "1200w solar generator" (1080wh cap.) power pack and plugged them in for full power. (JBL reduces output while on battery to extend batt life. I think it's a mistake, but whatever.) Running the power pack is super simple anyway. Set it down and plug in the boxes. LOLI did this specifically because my wife said they didn't get a DJ for the event soooo....These things lit up the entire parking lot like I had actually brought my DJ rig. In fact, it did every bit as good if not better than the DJ they had previously with an ElectroVoice tower and sub woofer combo set up. (The newer speaker set up with the sub and the thin tower that sticks up for highs and mids) While setting up, the entire parking lot thumped with MJ Thriller and everyone started dancing etc. They rocked the whole place no problem for the entire event. I was shocked. I knew they had guts, but didn't realize it was like that.The power meter on the power pack showed they were drawing about 500w on bass hits. The meter is not very responsive like that so that means these things were most like showing peaks of about 500w EACH. Totally believable as they are rated 250w RMS. It wouldn't surprise me if they couldn't peak out at 600-700w at times with enough input gain.My only complaint with these is the fact that they lower power output while on battery and that they don't talk to other generations of party boxes. I've also got 2 Partybox 100's I'd love to run with these as well.Oh actually there is one other MAJOR complaint. The "aux out" isn't a simple aux out. I had set them up in stereo and figured I would aux out one PB100 two each 310. Easy peasy. NOPE! The second you plug in the aux out port and try to daisy chain or whatever the speakers drop out of bluetooth and TWS and then you have to run everything mono and literally daisy chain one into the next into the next into the next.So you connect BT to one, then aux cable to speaker 2, then aux cable to speaker 3, speaker 4 etc. I've never seen anything like this in the pro audio world. It's STUPID. Give me an aux out that reflects what the speaker is playing and let me decide what I"m going to use it for. It would be SO MUCH easier to put 4 or 6 party boxes in stereo of two groups of 2 or 3 PB's like that. I don't have a 20 foot long aux cable to split into stereo like that and it's the wrong way to do it anyway. You lose to much signal trying to run a 20 foot aux cable. Again, it's STUPID and useless. If JBL could fix the app to get the models to talk to different generations etc and made the aux out act like an aux out they would be perfect.

Runs Practically Non Stop - Day In and Day Out

This was to be a replacement for the wired sound system we had at work which finally failed. Was looking for a bluetooth alternative due to the location change needed for the speaker placement. I work in an industrial mining warehouse that operates 24/7, which gets very dirty with lots of airborne dust and sand. This single speaker set up has been running almost non stop since I set it up. The only real exception is during team meetings and crew changes. This speaker plays a variety of everything from Metal, Country, EDM and Podcasts from different staff. I wasn't exactly sure what to expect when I made the decision to buy, but the product has more than exceeded our expectations. If it should ever fail, I won't be hesitating to make a second purchase, as it was well worth the cost.

Very good sound and bass
