Good · researched from 3 sources
The battery figure is the largest overperformance in this catalogue and the sound is the best TechGearLab measured in a group of fifteen. Turn the bass down in the app, and accept that a speaker this size with no microphone is an odd omission.
- Buy if
- Gardens, parties and anywhere that needs real volume · Long weekends away from power · Pools and rain, on IP67 and the fact it floats
- Skip if
- Carrying far, at more than two kilograms · Calls or voice control, since there is no microphone · Beaches, where two sources found sand getting in

Twice the claim
Bose says 20 hours. TechGearLab measured 43 hours 7 minutes.
That is the largest overperformance against a stated figure anywhere in this catalogue, and it runs directly against the pattern of every other portable speaker here. The Marshall Emberton II managed a third of its claim on SoundGuys' rig. The JBL Flip 6 and the Bose SoundLink Flex both came in under.
This one more than doubles it.
The qualifications are real but small. High volume shortens it. The USB-C socket that charges a phone draws on the same cell, and SoundGuys is careful to note it is not a separate battery bank. Recharging takes about five hours, which is the one place the specification disappoints.
First of fifteen
TechGearLab ranked this top of fifteen speakers with an overall 73 out of 100, scoring sound quality 8.4 and volume 8.3, and gave it their portable party speaker award.
They measured maximum output at 98 decibels. The Product Analyst got 98.2.
For context from this catalogue: the SoundLink Flex measures 88.4 dB and the UE Boom 4 measures 85. This is the one that will cover a garden with people in it.
The dissenting measurement
SoundGuys ran their MDAQS assessment and came back with an overall 2.7 out of 5: timbre 3.6, immersiveness 2.6, distortion 1.5.
A distortion score of 1.5 is poor, and it sits awkwardly against TechGearLab finding the output stayed cleanly punchy at maximum volume.
The Product Analyst supplies what may be the bridge: it ships very bassy, and wants around five or six decibels taken out of the low end in the app. An over-driven low end is exactly what produces distortion figures like that, and it is fixable in thirty seconds.
Turn the bass down before you judge it.
Built for outdoors, except for sand
IP67, submersible to a metre for half an hour, and it floats.
TechGearLab dropped it repeatedly and found silicon tears and small dents with no functional damage, and verified the submersion rating.
Both they and SoundGuys found the same weakness: sand works in through the front grille. SoundGuys adds that the ports are unprotected.
The omission
No microphone.
No calls, no voice assistant, and combined with no WiFi and no AirPlay, no multi-room either.
On a speaker at this price that is a deliberate choice rather than an oversight, and it keeps the product simple. It also means the thing on your patio cannot answer the phone, which the cheaper Sonos Roam can.
At more than two kilograms, TechGearLab scored portability 5.5 out of 10 and noted it fits a backpack while being a poor companion for anything strenuous. This is a speaker you carry to the garden and leave there.
How it scored
The overall 8.0 is the weighted average of these five criteria — we never adjust it by hand.
Sound quality
TechGearLab scored sound 8.4 and describes bold but balanced output with controlled bass. SoundGuys' MDAQS assessment scored distortion just 1.5 out of 5.
Value
TechGearLab ranked it first of fifteen. SoundGuys scored 7.4 out of 10 and advises waiting for a sale. The Product Analyst scored 8.1.
Build quality
IP67 and it floats. TechGearLab's drop testing produced silicon tears and small dents with no loss of function, though sand got in at the beach.
Ease of use
Multipoint and aptX Adaptive, but no microphone at all, no WiFi, no AirPlay and no voice assistant. SoundGuys notes the controls are not backlit.
Battery
TechGearLab measured 43 hours 7 minutes against a claimed 20. Recharging takes about five hours.

TechGearLab tested it against fourteen other speakers and supplies the measured battery, the maximum volume, the category scores, the drop and submersion testing and the ranking. SoundGuys supplies the MDAQS assessment scores, the dimensions and weight, the codec list and the observation about the USB-C output drawing on the main battery, scoring it 7.4 out of 10. The Product Analyst supplies the second volume measurement, the flotation confirmation and the practical EQ advice, scoring it 8.1. SoundGuys and TechGearLab disagree substantially about sound quality, and both assessments are reported.

SoundGuys measured almost seven hours beyond the claim. TechGearLab's frequency breakdown shows 36.2 dB of reduction in the highs and 15.6 in the lows.

Sonarworks measured up to ±4 dB of channel imbalance and ±3 dB of bass variation between units. That is a bigger difference than most of the arguments about how it sounds.

One lab scored comfort 4.6 out of 10 and found glasses cut wearable time to less than sixty minutes. Everything else about them is very good, which is the frustrating part.
