Removable, replaceable battery ; Great sound quality ; Handy shoulder strap

Default tuning is a touch bass-happy ; It’s not cheap

One of the best mid-size portable speakers around. Those who already own an older Xtreme don’t need to upgrade to the JBL Xtreme 4 but there are some welcome upgrades in tow, including a long-lasting, removable battery. But the key draws are, as ever,...

Stylish build ; 10,000mAH battery ; Splashproof ; Booming sound

Heavy ; Pricey ; Ports difficult to access

JBL's Xtreme isn't as good at pumping out high fidelity sound as its cousin, the Infinity One, but at that, it's still a fantastic speaker. Sound quality, battery performance and the splashproof design are on-par with what you'd expect for the price.

Bit pricey but you really do get what you pay for

Bit pricey but you really do get what you pay for.

There’s no mistaking why JBL dubbed this speaker the Xtreme. It looks great, packs a punch, has great battery life, can recharge your devices, and can even survive the beach, poolside, or slightly rainy day. If you’re in the market for a Bluetooth...

Look, BT is the future for us and I think JBL did a good job with this speaker. It isn’t meant for critical listeners and it is clearly intended to be toted around in college dorms, between party locations and used for all purpose listening. It does...

It’s splash proof, packs in powerful audio with strong bass, comes in several colors, doubles as a high capacity 10,000mAH battery pack, passive radiators create a neat effect, included strap makes it easy to transport the Extreme, rechargeable battery
