The JBL Partybox On The Go 2 is a great karaoke machine cause this speaker comes included with a wireless microphone and it has an AI Vocal removal tool so you can remove the lyrics from any song that you’re listening to and it does all of this locally on the device. However, the Partybox On The Go 2 sites pretty weird in JBL’s Partybox Lineup… its very portable thanks to the included shoulder strap, but you still want to be mindful with it. So today we’re going to compare it with both the JBL Boombox 4 and the Sony ULT Field 7 which you can also use for karaoke. Lets see which one is right for you.
Regarding pricing… this right here is going to be a deciding factor. The JBL Boombox 4 has a retail price of $550, which is a lot and its the same as the JBL PartyBox 320, just let that sink in. Where as with the Sony ULT Field 7, has a retail price of $500, but it likes to go on sale for $400 on a regular basis. And then there’s the JBL partybox On The Go 2 which has a retail price of $420, and it comes included with a wireless mic. Nonetheless if you want to pick any of these speakers up they’ll be linked down below or you can always press on the YouTube shopping button, and if you want to further support the channel then you can always watch some of the related videos in the description down below and you can press on the subscribe button as well.
Now when it comes to the design of these speakers, all of these speakers are on the larger side, but they are meant to be very portable. These speakers are roughly the same size and they all weigh in at less than 14 pounds. But I would actually argue that the JBL Partybox On the Go 2 is the most portable speaker here cause this speaker comes included with a shoulder strap, so carrying this speaker around is much easier, plus this shoulder strap also has a built in bottle opener, which can be very handy. And like I have said before, I think both Boombox 4 and ULT 7 should have shoulder straps as well. However both the Boombox 4 and ULT 7 are also more durable than the Partybox On The Go 2 here cause they have fabric wrapped bodies, so they are going to be able to stand up to more abuse, and they are also more water resistant. Where as with the Partybox, you can take it on the go with you, but you do have to be mindful with it cause it does have a mostly plastic body with a thin metal grill on the front, and it can’t get as wet. Just like your GF. So if you’re looking for something more durable, then you do want to go with either the Boombox 4 or ULT field 7.
But another thing that all of these speakers have in common is that they have a built in light feature. Now I feel that the light feature on the JBL Boombox 4 is pointless cause its tucked away in the passive radiator, so you can’t see it as much, and its not color changing. So I don’t bother with this light feature. Now the light feature on the Sony does change colors, but again since this light feature is tucked away in the passive radiator, it hard to see so I don’t feel that its worth actually using. But then there’s the Partybox On The Go 2, and this light feature is actually worth using. And since this speaker is using aura cast, you can always extend its light feature by adding JBL’s Partylight Sticks. But overall, you shouldn’t make your speaker purchase decision cause of a light feature… but the light feature on the JBL Partybox On The Go 2 is actually worth using.
However just keep in mind that if you do decide to use this light feature, that is going to take its toll on the battery life. Now the JBL Partybox On the Go 2 has an advertised battery life of 15 hours, just like the Encore 2. However just like the Encore 2, this advertised battery life of 15 hours is with this speaker playing at 50% volume and with the light feature turned off and with the bass boost feature turned off. but 50% volume on this speaker is a decent listening volume.
But real world use with this speaker playing at 80% Volume, and with the light feature turned on and with the bass boost feature turned on, the On The Go 2 is good for about 7 hours of playback time, and at max volume its good for about 3 hours of playback time… very similar numbers to the Partybox Encore 2 cause these two speakers have very similar speaker set ups.
Where as the Sony ULT Field 7 has an advertised battery life of 24 hours with it playing at 50% volume, and with the light feature turned off, but with the ULT feature turned on, which is good. Where as the JBL Boombox 4 has an advertised battery life of 34 hours, which is a lot, but thats with this speaker playing with stamina mode turned on which is going to severely reduce your bass.
With stamina mode turned off, which is how you should be using this speaker, the JBL Boombox 4 is going to have an advertised battery life of 28… but real world use with both of these speakers playing at 75% volume, and with their bass boost or ULT Feature turned on, both of these speakers are going to be good for around 10 hours of playback time. And 75% Volume on the Boombox 4 is noticeably louder than 75% Volume on the Sony.
But the really important thing here with both of these JBL’s speakers, is that you can swap out the batteries. Now removing the battery on the Partybox here is much easier than with the Boombox 4. Cause with the Boombox 4 you do have to undo some screws, and the reason that its like this is so that the Boombox 4 can keep its IP68 ratting making it more water resistant than the Partybox.
But the important thing here is, with both of these speakers you can get multiple batteries and keep the party going, or this is going to help extend the life of your investment cause when your battery dries, instead of having to buy a new speaker, you just need to buy a battery. However, the Partybox ON The Go 2 is using the 200 battery, so you can mix and match batteries with your Partybox on the go 2 and partybox 120 cause they are using the same battery. Where as with the Boombox 4, this speaker is using the 300 battery, so you can mix and match batteries with either the JBL Xtreme 4, JBL Xtreme 5, JBL partybox 320, 520 or even 720.
And to charge all of these speakers, they charge via an AC port, and with all of these speakers if you were to use them while they are plugged in, you are going to get a performance boost out of them. They are all going to get louder and they are going to have more bass. Just keep in mind that with JBL’s speakers, even if you’re going to use them while they are plugged in, their batteries need to be installed. Otherwise your speaker won’t turn off or they’ll shut off.
And when it comes to the ports on these speaker… surprisingly the JBL partybox on the go 2 and Boombox 4 are the same. They both have an audio jack so you can use them with a wired connection, but more importantly, they both have an USB C port which you can also use as a wired connection, but more importantly, you can use them to charge your own devices. Which I feel is super useful. Where as with the Sony, there no USB C port, instead it has a USB A port which I don’t feel is as useful in 2026.
But something that Sony does have here is that it has a 3 quarter inch input, so you can plug in a wired mic for karaoke or you can even plug in a guitar. However with the JBL partybox On the Go 2, this speaker also comes included with a wireless mic… and this is one of the better wireless mics out there cause this mic has a very tight cardioid pattern so its going to do a very good job of focusing on just your voice… and this mic also does a very good job of rejecting noise pollution when you’re handling this mic. And this mic sounds a lot better than your stranded wired mic.
However, with the Sony, you can also use it with dual wireless mics if you were to get Sony’s ULT Mic system. Now these mics don’t sound as good as JBL’s mic… however they still sound good enough and more importantly, you can do kakroke with a friend. Where as with the partybox ON The Go 2, if you want add more mics to this system, then you do have to get JBL’s easy sing system, and I feel that getting a Partybox On The Go 2 plus an easy sing system is hard to justify cause this set up gets very expensive very quickly, and at which point you’ll might as well get a partybox 120.
But then theres the JBL boombox 4… and sadly you can’t use this speaker for kakroke cause you can’t plug in a wired mic… and now you can’t plug in an Easy sing system into this speaker, trust me I’ve tired. So if you want a super portable speaker and you want to be able to use mics, then you either want to get a Sony ULT Field 7… or might as well spring for the JBL partybox 120 with easy sing system.
However something that does make the JBL partybox On the go 2 and easy sing system very imrepssive here is the AI vocal removal tool works locally on the device and it can remove the lyrics from any song that you’re playing. But so that you can see for yourself we’re going to jump into a demo.
Demo
So like you may have just seen, the AI vocal removal tool is very immpressive, and you can also add this feature to any JBL Partybox Speaker with the easy sing system. However keep in mind, if you were to pair your Partybox On The Go 2 with any other speaker using Auracast, then you can’t turn on the AI vocal removal tool, and your mic audio is only going to come out of the Partybox On The Go 2.
But with all of that being said, lets talk about sound. When it comes to speaker set ups, all of these speakers are fairly diffrent. Now the JBL partybox On The go 2 has a single frontward firing woofer with exhaust ports that shoot out the front and it has dual frontward firing tweeters. Where as the Sony ULT field 7 has dual frontward firing woofers, dual frontward firing tweeter and dual passive radiators that shoot out the sides, and this is a fairly standard speaker set up. Where as the JBL Boombox 4 also has dual frontward firing woofers, dual frontward firing tweeter and dual passive radiators that shoot out the sides… but what is new is that this speaker now has a passive radiator that shoots out the back for added bass. And all of these speakers have a bass boost mode. But now we’re going to jump into the sound test. All of these speakers are playing at 75% volume while unplugged.
Sound test
So when it comes to sound quality, think these speakers sound fairly diffrent from one another. Now overall I think the Sony ULT filed 7 has the best instrument separation here and sounds the most open. Cause both of these JBL’s sound a little more narrow by comparison. And especially with the Boombox 4, this speaker likes to put more of an emphasis on the mids and highs, making it sound little nasally. But still, I think the Boombox 4 sounds better than the JBL partybox On The Go 2. And when it comes to the bass on these speakers, the Boombox 4 has the most amount of kick in its bass here cause this speaker has a total of 3 passive radiators, where as the Sony only has 2. But then there’s the Partybox here who’s bass is mostly on the audible side cause its exhaust ports shoot out the front. Now don’t get me wrong, the bass on this speaker is good and its very clean… but it doesn’t have as much kick to it like these other speakers. But overall, yes I do feel that the Sony ULT field 7 still have the best instrument separation here and I think the Boombox 4 sounds better than the JBL partybox On The Go 2.
and when it comes to max volume performance. Overall all of these speakers are going to be fine for like a 15 person get together… but I do have to see that the Sony doesn’t get the loudest here, and that’s cause this speaker doesn’t put as much emphasis on the highs like these other JBL speakers. Where as the Partybox does get a little louder, and the Boombox 4 does get the loudest here, but that’s cause this speaker is put an emphasis on the highs, so at max volume it seems loud but it might not seem as full. But like I mentioned earlier, with all of these speakers, if you were to use them while they are plugged in you will get a performance boost out of them, they’re going to get louder and they are going to have more bass… but overall, the JBL Boombox 4 is still the loudest here.
But finally lets talk about pairing these speakers up with other speakers. Now with all of these speakers if you have two of the exact same speakers then you can wirelessly pair them up and get them to play in left and right stereo mode… however they have to be 2 of the exact same speakers.
Now the the Sony ULT field 7 is using wireless party chain so you can pair it up with any other Sony speaker that also using wireless party chain like either an ULT Field 5 or to and ULT field 3 and you can also pair it up with Sony’s older speakers like lets say the XG500 or XE300… or you can also pair it up with Sony’s larger Box speakers like either a Tower 10 or the Tower 9. The only thing is, you cant pair your ULT field 7 with an ULT Field 1 cause it doesn’t have wireless party chain.
But then there are these other two speakers which are using Auracast, so you can pair them up to JBL’s smaller speakers that are also using aura cast like lets say a Boombox 4, a charge 6, an xtreme 4 Xtreme 5, flip 7, clip 5, Go 5 or go 4 or you can pair them up to JBLs larger Partyboxes like an Encore 2, 120, 320, 520, 720 or ultimate and you can get them all to play in sync…
however you can not pair up either of these two speakers up to any of JBL’s older speakers that are using Partyboost… and you can’t pair your JBL Partybox On The Go 2 up to any of JBL’s older Partyboxes that are using TWS like an original Encore, or a 110, 310, or 710.
And like I mentioned earlier, if you pair up your Partybox On the go 2 up to any other speaker using aura cast, then you won’t be able to turn on the ai vocal removal tool and your mic audio is only going to come out of the Partybox.
So with all of that begin said, the JBL Partybox On The Go 2 is an impressive speaker. The AI vocal removal tool makes karaoke very easy, plus it comes included with a very good wireless mic. Plus the Partybox On The Go 2 is very easy to take on the go with you cause it comes included with a shoulder strap. But its hard to justify this speaker cause if you want to do kakroke with friends, you are going to need to get JBL’s easy sing mic system… and even though this speaker is portable, its not durable. So if you want a box speaker for karaoke, just get the Partybox 120 and an easy sing system. Its going to cost the same and the performance is going to be way better. But if you want a smaller speaker to do karaoke with, then the Sony ULT field 7 is a great option cause its a lot more durable and you can plug in a wired or wireless mic. And then there’s the JBL Boombox 4, no you can’t plug in a Mic into this speaker, but it does out preferom the JBL partybox On the go 2.
