JBL PartyBox Encore Essential 2 review

The JBL PartyBox Encore Essential 2 is a 13.67 lb (6.2 kg) battery-powered party speaker running one 5.25-inch (135 mm) woofer and two 0.75-inch (20 mm) dome tweeters at a rated 100 W RMS, with a published frequency response of 40 Hz to 20 kHz (-6 dB). The 34 Wh battery is quoted at up to 15 hours and charges in under 3.5 hours with the speaker off. The reason to buy it is the input panel: a microphone input (20 mV RMS), a guitar input (100 mV RMS) and a 3.5 mm aux input (370 mV RMS) — a combination almost nothing else at this size and price carries. The catches are real: IPX4 splash resistance only, no dust rating, no microphone included, and a cabinet that needs two hands.

We have recommended this speaker on several roundups — speakers with a microphone input, the best outdoor party speakers, the best speakers for teachers — without ever giving it a page of its own. This is that page, and it is more critical than those shorter mentions because a review has room to say what a tile cannot.

Every figure below comes from JBL's own published specification sheet for the model. Nothing here is measured by us; the one independent observation is attributed. How we pick sets out the method.

What it does well

The microphone input is the whole product, and it is genuinely rare. A 20 mV RMS mic input on a battery-powered speaker means karaoke in a garden, a toast at a wedding, a coach addressing a field, an instructor over a class — none of which a normal Bluetooth speaker can do at any price. Most speakers marketed for karaoke have no microphone input at all; they pair with a Bluetooth mic that mixes on the phone, which adds latency and a second thing to charge. This one takes a cable. The best speakers with a microphone is the full, and short, list of what else does.

There is a guitar input next to it, at 100 mV RMS. That is a separate jack with its own gain staging, not the mic socket relabeled. It will not replace a guitar amp — there is no overdrive, no cabinet simulation, no effects loop — but for an acoustic with a pickup at a campsite or on a porch, it is the difference between being heard and not. Very few portable speakers offer it.

It has a 3.5 mm aux input, and that is quietly a big deal. JBL publishes an Aux-In at 370 mV RMS. The entire portable category has abandoned the analogue jack — the JBL Flip 7, the Charge 6, the Xtreme 4 and the new Xtreme 5 all go without one — and the usual answer for anyone with a turntable or a TV is the far more expensive Bose SoundLink Max. This speaker does it for less. Speakers with an aux input is the list, and this one belongs near the top of it.

Fifteen hours off a battery, in a class where most rivals need a wall. The PartyBox name usually means mains power. This model carries a 34 Wh Li-ion cell quoted at up to 15 hours, and that is what makes everything above portable rather than merely moveable. It charges in under 3.5 hours with the speaker off, and the USB port will charge a phone at up to 11 V / 2 A.

A published 40 Hz floor at -6 dB. That is honest labeling — plenty of manufacturers quote a floor without saying at what tolerance — and it is a low number for a single 5.25-inch woofer. In practice this is a speaker with real low end, which is the point of a 100 W box. Cheap speakers with good bass is where that gets compared against things costing a quarter as much.

AI Sound Boost, Auracast and the app. JBL's processing keeps the woofer clean closer to its limit, Auracast pairs two of them into true stereo or links them into a wider JBL chain, and the PartyBox app handles EQ and the lightshow. The lightshow is a genuine party feature rather than an LED ring — strobes and patterns, not a glow. Speakers with lights is the honest take on how much that is worth.

Where it cuts corners

IPX4 is the weakest water rating on this site, and the X is a gap rather than a zero. Splashes and light rain, nothing more. No submersion, no jet resistance, and the X in place of the first digit means no dust rating was tested at all — which for an outdoor speaker is the quiet long-term failure. Do not take this to a beach, a pool or a worksite. What IPX7 and IP67 actually mean explains why that first digit decides how long a speaker survives, and waterproof speakers under $100 is the right list if water is anywhere in the picture.

No microphone is included, despite the mic input being the reason to buy it. JBL's box contents are the speaker, a quick-start guide, a safety and warranty card and an AC power cord. If karaoke is the plan, budget for a wired microphone and a long cable on top of the speaker. It is a conspicuous omission and it catches people out.

13.67 lb, and it is a box with a handle rather than something you sling. 319.5 x 342 x 260.4 mm is a substantial object — more than twice the weight of the JBL Xtreme 5, which is itself the heaviest conventional portable we cover. It moves from a car to a garden. It does not go on a bike, in a backpack or up a trail. What size speaker do I need is worth reading before you commit to this footprint.

It is front-firing, so it has a front row. RTINGS note that it sounds noticeably different depending on your listening angle, and that voices can sound muffled if you stand behind it. For a speaker bought to face a crowd, that is the correct design — but it means you cannot drop it in the middle of a table and expect everyone to hear the same thing, the way a 360-degree speaker lets you. Aim it.

One hundred watts is less than the number suggests, and cheaper party speakers quote more. Rated 100 W RMS to IEC60268 is an honest measurement standard, which is more than many rivals offer — but you will find speakers at half the price advertising bigger figures measured less rigorously. The output here is ample for a garden or a classroom and it is not a stadium. How many watts is loud is the page that makes those numbers comparable, and the loudest for the money is where this sits against the field.

No USB media playback in EMEA, and FAT-only elsewhere. JBL's sheet notes the USB file playback feature is not available in the EMEA region, and where it is available the drive must be FAT16 or FAT32 and the files MP3, WAV or FLAC. A small thing, and the kind of small thing that is irritating to discover after purchase.

It is the most expensive thing in its own use case. If you do not need the microphone or the guitar input, you are paying for a panel you will not use — and the Tribit StormBox Blast and Soundcore Motion Boom, both in the picks below, deliver outdoor volume for substantially less. The best speakers for the money is the wider version of that argument. The input panel is the only reason to pay the difference. It is a very good reason if you need it.

Alternatives worth knowing about

The Encore Essential 2 itself, summarized

JBL PartyBox Encore Essential 2

The cheapest genuinely portable speaker here with a real microphone input.

What it does well

A 20 mV mic input, a 100 mV guitar input and a 370 mV 3.5 mm aux input on a speaker that runs 15 hours off its own battery.

Where it cuts corners

IPX4 splash resistance with no dust rating at all, no microphone in the box despite the mic input being the point, 13.67 lb in a two-handed cabinet, a front-firing pattern that sounds wrong from behind, and cheaper party speakers that advertise bigger wattage figures.

Who it is for

Karaoke nights, toasts, coaches, instructors, and anyone who needs a real cable input on a speaker that runs off a battery.

• Battery: Up to 15 hours
• Water rating: IPX4 — splash-resistant only. Not submersible, no dust rating

If you only need the volume

Tribit StormBox Blast

The loudest thing we are willing to call good value.

What it does well

Outdoor-scale output and a long battery for markedly less money, in a cabinet that is easier to carry. If nobody is going to sing, this does the job the Encore Essential 2 does without the panel you are paying for.

Where it cuts corners

No microphone input, no guitar input, and none of the karaoke-oriented tuning. You also give up Auracast's compatibility with the rest of JBL's current range.

Who it is for

Gardens and tailgates where the speaker only has to play music.

• Battery: Over 32 hours in independent testing
• Water rating: IPX7 — submersible to 1 m for 30 minutes

If it has to survive weather

JBL Xtreme 5

One big woofer instead of two small ones, IP68 and a drop rating — the most rugged Xtreme, and the heaviest.

What it does well

IP68 and a drop claim against this speaker's IPX4, a 40 Hz floor from a bigger single woofer, 24 hours plus Playtime Boost, a powerbank and a shoulder strap with floating hooks. Half the weight, and it will tolerate a downpour.

Where it cuts corners

No microphone input, no guitar input and no aux input of any kind, so it cannot do the thing this page is about. It also costs more and arrives without a charger.

Who it is for

Anyone who wants outdoor ruggedness rather than an input panel.

• Battery: Up to 24 hours, plus 4 more with Playtime Boost; 10 minutes of charging gives about 2 hours
• Water rating: IP68 — dust-tight and sealed against continuous immersion. JBL also calls it drop-proof, without publishing a drop height
• Output: One 98 x 145 mm woofer and two 20 mm tweeters; 1 x 90 W RMS plus 2 x 20 W RMS on AC power, 1 x 60 W RMS plus 2 x 15 W RMS on battery
• Weight: 6.38 lb (2.9 kg)

If the price is the problem

Soundcore Boom 3i

A floating outdoor speaker that rights itself in chop, built for the water and the dirt.

What it does well

Outdoor volume, a carry handle, a long battery and a water rating this speaker cannot match, for a fraction of the money. On a per-dollar basis it is the better speaker for almost any use that does not involve a cable.

Where it cuts corners

No mic, guitar or line input, a smaller cabinet and less low-frequency reach, and no lightshow worth the name.

Who it is for

Value buyers who want a loud outdoor speaker and nothing more complicated.

• Battery: 16 hours
• Water rating: IP68 — submersible and dust-tight, lab-tested to 240 hours of salt spray, and it floats upright
• Output: 50 W with BassUp 2.0
• Weight: 1.7 lb (780 g)

Who should skip it

• Anyone going near water. IPX4 is splashes only, with no dust rating. Waterproof speakers under $100 and the best for a pool are the right lists.
• Anyone who has to carry it any distance. 13.67 lb with no strap in the box. What size speaker do I need is the sanity check.
• Anyone who does not need an input panel. Without the mic, guitar or aux jack, this is an expensive way to buy volume. The loudest for the money spends it better.
• Anyone expecting a microphone in the box. There isn't one. Budget for a wired mic and a cable.
• Anyone who needs 360-degree sound. It is front-firing and it is meant to be aimed. Mono vs stereo covers the dispersion question.

If karaoke is the whole reason you are here, the best Bluetooth speakers with a microphone puts this speaker against the handful of genuine alternatives. If it is a party in a yard, the best outdoor party speakers is the roundup. And if the real requirement is a cable from a turntable, a TV or a mixer, speakers with an aux input is the page — this is now one of the cheapest battery-powered answers on it.
