The JBL Charge 6 and UE Boom 4 are the two most popular portable Bluetooth speakers under $200, and the rivalry between them has gone on for years. JBL goes bigger and louder; UE goes rounder and 360-degree. Both are genuinely excellent. This comes down to listening preferences more than objective performance.
JBL Charge 6
The JBL Charge 6 is louder and has better bass; the UE Boom 4 fills a room more evenly with 360-degree sound.

Sound: Directional vs 360-Degree
The JBL Charge 6 has a directional sound design — it projects most of its audio forward. The result is strong, punchy sound in front of the speaker with significant volume drop behind it. For a speaker sitting on a table with everyone gathered on one side, this is fine.
The UE Boom 4 is cylindrical and projects sound in all directions equally. Set it in the middle of a group of people or on a kitchen counter with people all around and everyone hears the same thing.
If your use case is pointing a speaker at you on a desk: JBL. If your use case is setting a speaker in the middle of a party: UE Boom.
Volume and Bass
The JBL Charge 6 gets louder — significantly so. For outdoor use where volume is the limiting factor, JBL wins. The passive radiators on the Charge 6 create more physical bass pressure than the UE Boom 4 can match.
JBL's bass response is boosted and present. At maximum volume outdoors it moves air in a way that the more balanced UE Boom 4 doesn't.
The UE Boom 4 is tuned more neutrally — bass is present but not exaggerated, mids are clear, and highs are well-extended. It sounds more accurate; the JBL sounds more fun.
Battery and Durability
JBL claims 24 hours battery life on the Charge 6; UE claims 24 hours on the Boom 4 as well. Real-world testing at moderate volumes confirms both sit around 20-22 hours. Equivalent here.
The Charge 6 also has a USB-A output port to charge your phone — useful when you're away from power outlets. The UE Boom 4 doesn't have a charging port.
Both are IP67 rated — submersible to 1 meter for 30 minutes. Both float in water. Both handle pool and beach environments. Durability is a tie.
Features and App
UE's app lets you adjust EQ and access the Party Up feature, which links multiple UE speakers together. Boom and Megaboom can play in sync. The Boom 4 also has a programmable outdoor button.
JBL's PartyBoost links multiple JBL speakers (Charge, Flip, Pulse series) for synchronized playback. The JBL Portable app has EQ, speaker lock, and personalization features.
Both apps are well-designed. UE's Party Up ecosystem might be larger simply because the Boom line has been dominant for longer.

FAQ
Can the JBL Charge 6 and UE Boom 4 play together?
No — JBL's PartyBoost and UE's Party Up are proprietary systems that only work within their own product families. You can't sync a JBL and a UE speaker together.
Which speaker sounds better for music in a kitchen?
The UE Boom 4 — its 360-degree projection fills the kitchen evenly no matter where it's placed on the counter. The JBL would leave half the kitchen quieter depending on which way it's pointed.
Is the Charge 6 worth the extra $30 over the Boom 4?
Yes, if you need the USB charging port or want more outdoor volume. No, if 360-degree sound is more useful to your use case. Both are excellent choices at their respective prices.
