JBL - Go 4

I avoid click-bait titles, but having spent a lot of time with the newer Clip 5 and Go 4 from JBL, I was honestly shocked by how well the Select 4 Go performs comparatively, given its $29 price point. Build quality falls a little short of JBL, and the multi-speaker pairing isn't quite as extensive, but still - I've tested a fair amount of speakers, and I'd have a hard time recommending something else for a budget-focused buyer looking for something like the Go 4.

JBL Go 4 is a little smaller and lighter than the Clip but still has a big sound for the size. This is a good choice if you’re traveling carry-on only or onebag.

Whatever you decide to go with, you should audition the JBL GO 4. Its is 193g and sounds amazing for its size. If you do decide to go larger, you can use the GO 4 as a baseline. I also have the mind blowing Bose Soundflex v2 but at 589g, it’s not fun for my desire to travel minimally. The OP however may find it wonderful dropping from a 3lb speaker to a 1.25lb speaker. But for me, the half pound JBL Go 4 on any trip!

I heard its barely any better than go 3. My select 4 go is so much better than go 3.

You can always try the used market. And when it's in your area take something with you to test the latency with. I have a JBL Go. The speaker itself is horrendous, lacks a lot of low-end but the latency is not an issue It has a 3.5cm jack and I just tested it. It works. Maybe that is something to try? But remember, the quality is always horrible especially with a single speaker solution as lows and hi's need to go through the same little speaker.

I like the Wonderboom 4 by UE. I have version 2 good sound and a small footprint. Soundcore glow mini should be good. I heard the regular Glow : good sound. JBL go is solid too.
