Verdict: The SOUNDBOKS Mix is worth its $799 US list price for people who need a very loud, battery-powered speaker for outdoor gatherings, car camping or other rugged, mobile use. It reaches a manufacturer-rated 121 dB, runs for a claimed 40 hours at mid volume, uses a replaceable LiFePO4 battery and has an IP65-rated electronics coating. Its drawbacks are equally clear: at 21.4 pounds it is portable between nearby locations rather than backpack-friendly, Bluetooth is only version 4.2, the wired input selection is limited, and no charger is included. For a small yard or indoor room, it is likely overkill; for a large group that values output and durability, it is a focused and unusually capable party speaker.
Is the SOUNDBOKS Mix worth $799?
Yes, if your priority is high-volume outdoor sound with long battery endurance and repairable hardware. The Mix launched in March 2026 and carries a $799 US list price; Tom’s Guide also reported an Amazon price of £599 in the UK. Those figures are regional and can change, so check the price shown for your market before ordering.
The value proposition is not small-room fidelity or maximum convenience. You are paying for a 121 dB claimed peak, a 99.84 Wh removable battery, a weather-resistant build and the ability to move a full-size party system without a wall outlet. A smaller Bluetooth speaker will be easier to carry, while a home-oriented model may offer more inputs or newer wireless standards. The Mix makes sense when loudness, runtime and toughness matter more than compactness.
Recommended Free Tools
Who should buy it
- Hosts of large backyard, beach, tailgate or campsite gatherings who need headroom at outdoor listening distances.
- Campers and event users who want a replaceable battery rather than a permanently sealed pack.
- Owners who may expand later with other compatible SOUNDBOKS speakers through TeamUp.
- Buyers comfortable purchasing a USB-C PD charger separately.
Who should skip it
- Anyone who mainly listens in a bedroom, office or small apartment, where 121 dB is unnecessary.
- People who need a speaker that can be carried long distances without a vehicle or a second person.
- Listeners who expect current Bluetooth features or several analog and microphone inputs at this price.
- Buyers who need a charger in the box and do not want an additional accessory purchase.
What are the SOUNDBOKS Mix’s key specifications?
The Mix combines a single 10-inch woofer, a 1.2-inch dome tweeter and two 72 W RMS Class-D amplifiers. Its effective frequency range is 40 Hz–20 kHz, and the manufacturer lists a maximum sound-pressure level of 121 dB.

| Specification | SOUNDBOKS Mix | What the figure means |
|---|---|---|
| Maximum sound-pressure level | 121 dB (manufacturer rating) | Very high output intended for large outdoor groups; the figure is a claimed maximum, not an independent laboratory measurement. |
| Amplification | Two 72 W RMS Class-D amplifiers | Dedicated amplification for the woofer and tweeter section. |
| Drivers | One 10-inch woofer and one 1.2-inch dome tweeter | A large low-frequency driver paired with a separate high-frequency driver. |
| Effective frequency range | 40 Hz–20 kHz | The published operating range; room, placement and volume affect what you actually hear. |
| Battery | 12.8 V, 7.8 Ah LiFePO4; 99.84 Wh rated capacity | A removable lithium-iron-phosphate pack designed for high cycle durability. |
| Claimed runtime | 40 hours at mid volume; 8 hours at full volume | Use the mid-volume number as an endurance claim, not a guarantee at maximum output. |
| Wireless | Bluetooth 4.2 | Basic Bluetooth playback without the feature set of newer generations. |
| Wired input | One 3.5 mm stereo input | Useful for a single analog source, but fewer physical connection options than larger systems may provide. |
| Multi-speaker linking | SKAA TeamUp, up to five compatible SOUNDBOKS speakers | Allows a compatible group of speakers to be linked for a larger setup. |
| Weight | 21.4 lb | Manageable for a short carry, but substantial for hiking or repeated stairs. |
| Dimensions | 19.1 × 13.5 × 10.9 inches | Measure your vehicle, storage shelf and carrying route before buying. |
How loud is the SOUNDBOKS Mix?
The manufacturer rates the Mix at a maximum of 121 dB. That is enough output for a large outdoor gathering, where sound disperses quickly, but the number should be treated as a specification claim rather than a guaranteed listening level at every frequency or distance. No independent laboratory SPL measurement was available for this review.
What 121 dB means in practice
Outdoor listeners usually need more acoustic headroom than indoor listeners because there are no nearby walls to reinforce bass and no ceiling to contain sound. The Mix’s 10-inch woofer and two 72 W RMS amplifiers are designed around that use case. At moderate settings you can leave room for musical peaks; at maximum settings, placement, music content, battery state and the surrounding crowd all affect the result.
Do not interpret the maximum rating as a recommended everyday level. Prolonged exposure to very loud music can damage hearing. Keep the speaker aimed away from people at close range, start below maximum volume and follow local noise rules for public spaces.

SOUNDBOKS claims up to 40 hours at mid volume and up to 8 hours at full volume. Those are the two published operating points; playback time varies with volume, bass-heavy material, temperature, wireless conditions and battery age.
| Use case | Published runtime | Planning implication |
|---|---|---|
| Mid-volume playback | Up to 40 hours | Suitable for a multi-day camp or repeated gatherings when the speaker is not driven continuously at maximum. |
| Full-volume playback | Up to 8 hours | Plan for a same-day event, a spare battery or access to USB-C PD charging for longer maximum-output sessions. |
The pack is a 12.8 V, 7.8 Ah LiFePO4 battery rated at 99.84 Wh. LiFePO4 chemistry is commonly chosen for cycle life and thermal stability, and the Mix’s battery is replaceable rather than permanently sealed inside the cabinet. That matters if you expect years of frequent use: a worn pack does not automatically make the whole speaker disposable.

How to get the longest runtime
- Use the lowest volume that covers the audience instead of running at maximum continuously.
- Keep the speaker out of extreme heat and cold; battery performance changes with temperature.
- Charge before an event and carry a charged replacement if the event must continue through a full-volume day.
- Store the battery and speaker dry, and avoid leaving a depleted pack unused for long periods.
Is the SOUNDBOKS Mix waterproof and rugged?
The manufacturer describes an IP65-rated coating for the electronics. IP65 indicates dust protection and resistance to water jets; it is not an immersion rating. Treat the Mix as weather-resistant for outdoor use, not as a speaker that can be submerged, left in standing water or exposed indefinitely to driving rain.
What protects the cabinet
- ABS/polycarbonate construction forms the main enclosure.
- Silicone ball corners help protect impact points during transport.
- A reinforced top hat provides a strong mounting and carrying area.
- The steel grille is detachable and replaceable, so a damaged grille does not necessarily require replacing the entire speaker.
WIRED praised the IP65 rating, rubberized corners, replaceable grille and replaceable battery in its 8/10 review. Those are practical ownership advantages, but they do not remove the need to close ports, keep the unit out of standing water and dry it after wet conditions. Before storing it, inspect the grille, corners and connectors for grit or moisture.

How portable is a 21.4-pound speaker?
The Mix weighs 21.4 pounds and measures 19.1 × 13.5 × 10.9 inches. That makes it portable between a car and a nearby campsite, patio or beach setup, but not effortless backpack transport. A short carry on level ground is realistic; long trails, stairs and repeated moves may require two people or a cart.
Measure the route you use most. Check that the speaker fits through doors, into your vehicle and onto the storage shelf where it will live. The dimensions also affect placement: leave clearance around the cabinet and keep the front grille unobstructed so the woofer and tweeter can project cleanly.
What connections does the Mix have?
Bluetooth 4.2 handles wireless playback, and one 3.5 mm stereo input provides a wired alternative. SKAA TeamUp can link up to five compatible SOUNDBOKS speakers. Tom’s Guide noted that the Mix has fewer connection ports than larger models, so it is best viewed as a straightforward playback system rather than a small portable PA with a broad input panel.

Bluetooth 4.2 considerations
Bluetooth 4.2 is adequate for ordinary phone and tablet streaming, but it is an older generation in a 2026 product. Newer Bluetooth versions can offer improvements in efficiency, range management or feature support, yet the exact experience still depends on the source device and environment. If your setup relies on a particular codec, multipoint behavior or low-latency mode, confirm compatibility before purchase; those capabilities are not established by the published specification.
Using the wired input
The 3.5 mm stereo jack is useful when you want to avoid wireless interruptions or connect a source with a headphone output. Because there is one analog input, plan the signal chain before a party: a mixer or source selector may be needed if several wired devices must be connected at once.
Linking speakers with TeamUp
TeamUp supports a group of up to five compatible SOUNDBOKS speakers. Confirm that every unit supports the required TeamUp mode and update or pair them before guests arrive. A linked system can cover a wider area, but it also increases total cost, setup time and the number of batteries that must be charged.
Does the SOUNDBOKS Mix come with a charger?
No. The cited US product-page listing does not include a charger. Charging requires a USB-C Power Delivery supply rated at 65 W or higher, and the manufacturer’s dedicated charger is sold separately.
The official listing gives The Charger a $69 price and The Battery a $199 price. At the listed US prices, adding the charger brings the speaker-and-charger total to $868 before tax; adding both accessories brings it to $1,067. These are arithmetic totals from the cited prices, not a bundle price, and availability or regional pricing can change.

What to check before ordering
- Confirm that you already own a USB-C PD charger capable of at least 65 W, or add a compatible charger to the order.
- Check the connector and power specifications rather than assuming any phone charger will work.
- If you need all-day maximum-volume playback, price a spare battery before the event instead of discovering the limitation afterward.
- Verify stock, local taxes, shipping and regional compatibility for the charger and replacement battery.
How does the Mix sound?
Tom’s Guide described its hands-on sound as ground-shaking bass, crisp treble and refined mids. Those are listening impressions, not instrumented measurements, but they indicate the intended tuning: energetic low end for outdoor music with enough treble presence to keep vocals and percussion clear.
WIRED rated the speaker 8/10 and praised its loudness, durability and endurance. The review also called out the size, weight, missing charger and the fact that the speaker is overkill for small yards. Taken together, the independent coverage supports a clear pattern: the Mix’s strongest qualities appear when it is used as a high-output outdoor system, while its compromises become obvious in compact spaces or convenience-focused setups.
How should you compare the Mix with Soundboks 4, Soundboks Go, JBL or Marshall party speakers?
Choose by use case and complete ownership cost rather than by peak loudness alone. Tom’s Guide characterized the Mix as the Soundboks 4’s smaller sibling and said it effectively replaces the Soundboks Go as the brand’s most portable party speaker. The Mix is the only model in this comparison with a complete set of figures in the available specifications, so competitor claims should be checked against their current regional pages before you buy.
| Decision question | Why it matters for the Mix | What to verify on another speaker |
|---|---|---|
| Do you need maximum outdoor output? | The Mix is rated at 121 dB and uses a 10-inch woofer with two 72 W RMS amplifiers. | Maximum SPL, whether it is a peak or continuous figure, and the conditions used to obtain it. |
| How far will you carry it? | At 21.4 lb and 19.1 × 13.5 × 10.9 inches, it is best for short moves. | Weight, handles, dimensions and whether a cart or second person is practical. |
| Will the event last overnight? | Runtime is claimed at 40 hours mid-volume or 8 hours full-volume. | Runtime at the volume you actually intend to use, not only an economy-mode claim. |
| Could the speaker get wet? | Its electronics have an IP65-rated coating, but that does not mean immersion protection. | The exact IP rating, protected openings and warranty treatment for water exposure. |
| Do you need several sources? | The Mix has Bluetooth 4.2 and one 3.5 mm stereo input. | Bluetooth generation, codec support, microphone or instrument inputs and output connections. |
| What is the delivered cost? | The $799 US list price excludes the charger; a 65 W-or-higher USB-C PD supply is required. | Whether charging hardware, batteries and essential cables are included. |
| Can you repair or expand it? | The battery and grille are replaceable, and TeamUp supports up to five compatible units. | Availability and price of replacement parts, multi-speaker limits and support terms. |
How do you set up the SOUNDBOKS Mix for an event?
Prepare the speaker before guests arrive, especially because the charger is not included and maximum-volume runtime is much shorter than the mid-volume claim.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Confirm power: Charge the installed battery with a USB-C PD supply rated at 65 W or higher, or use the manufacturer’s charger. Allow enough time for a full charge before leaving for the venue.
- Inspect the hardware: Check the grille, silicone corners, connectors and battery compartment. Do not operate it while wet or with debris in a connection.
- Choose placement: Put the cabinet on a stable surface with the front unobstructed. Aim it toward the audience and keep it away from standing water and direct splash.
- Pair a source: Open the phone, tablet or computer’s Bluetooth settings, select the SOUNDBOKS Mix and play a short test track. If wireless conditions are crowded, use the 3.5 mm stereo input.
- Set a safe level: Start below maximum volume, walk the listening area and raise the level only as needed. Avoid placing listeners directly beside the grille.
- Link additional units if needed: Use SKAA TeamUp with compatible SOUNDBOKS speakers, pairing and testing every unit before the event starts.
- Pack down carefully: Disconnect the source, remove surface moisture, let the cabinet dry and store the battery according to the manufacturer’s guidance.
What are the Mix’s main advantages and drawbacks?
Advantages
- Very high claimed output at 121 dB for outdoor gatherings.
- Long claimed endurance of 40 hours at mid volume.
- Replaceable 99.84 Wh LiFePO4 battery.
- Rugged ABS/polycarbonate enclosure with silicone corners and a replaceable steel grille.
- IP65-rated electronics coating for dust and water-jet resistance.
- TeamUp expansion for up to five compatible SOUNDBOKS speakers.
Drawbacks
- Heavy and bulky compared with ordinary portable Bluetooth speakers.
- Only Bluetooth 4.2 and one 3.5 mm stereo input.
- No charger in the cited US listing; a 65 W-or-higher USB-C PD supply is required.
- Full-volume runtime is claimed at 8 hours, far below the mid-volume figure.
- $799 is difficult to justify for small rooms or casual low-volume listening.
- The 121 dB and battery figures are manufacturer claims, not independent laboratory results.
What should you check before buying?
- Venue: Confirm that your typical audience and outdoor area genuinely need this level of output.
- Transport: Measure your vehicle and storage space, and plan how a 21.4-pound cabinet will be moved.
- Power: Budget for a compatible charger if you do not already own a 65 W-or-higher USB-C PD supply.
- Runtime: Base your plan on 8 hours if you expect continuous maximum-volume playback, not on the 40-hour mid-volume claim.
- Weather: Treat IP65 as protection from dust and water jets, not permission to submerge the speaker.
- Expansion: If you might add units, confirm that every planned speaker is compatible with TeamUp and include extra batteries and charging time in the budget.
- Hearing safety: Position the speaker responsibly and keep exposure time reasonable at high levels.
Final buying advice
The SOUNDBOKS Mix is a specialized answer to a specific problem: delivering loud, durable, battery-powered music outdoors without carrying a full sound system. Its 121 dB rating, 40-hour mid-volume claim, replaceable LiFePO4 battery and reinforced enclosure make it compelling for campsites, tailgates and large parties. The same design makes it unnecessarily large for a small yard and less convenient than a conventional portable speaker because of its weight, older Bluetooth standard, limited wired input and missing charger. Buy it when those trade-offs match your events; otherwise, spend less on a smaller system or choose a model with the connections and included accessories you actually need.

Frequently Asked Questions
Can the SOUNDBOKS Mix be used in the rain?
It can tolerate dust and water jets under the stated IP65 electronics protection, but it is not rated for immersion. Keep it out of puddles, pools and prolonged heavy rain, and dry the cabinet before storage.
Can I replace the SOUNDBOKS Mix battery myself?
The battery is designed to be replaceable, and the official replacement is listed as The Battery. Check the current regional part listing and follow the manufacturer’s installation and safety instructions rather than using an unverified pack.
How many Mix speakers can play together?
SKAA TeamUp supports up to five compatible SOUNDBOKS speakers. The other units must support the same TeamUp system, so confirm compatibility before purchasing additional speakers.
Is a phone charger enough to charge the Mix?
Only if it is a USB-C Power Delivery supply rated at 65 W or higher. Many basic phone chargers do not meet that requirement, which is why the required charging specification should be checked before the event.
