We set up the pair playing a 50% volume (60dB) and achieved 10 and 18 hours. We did not have time to rerun the tests at 75% (70dB) and 100% (>80dB), but we expect times to be a ratio of our tests.

Recharge time is slow at a little over five hours. An 18W PD charger comes with MEGABOOM 3 but is MIA for BOOM 3. So, you can use a 5V/2A or 3A or a USB-PD charger there.

Both support the Power Up adaptor disk option that sits under the base. Note that most third-party micro-USB cables will not fit the charge socket as it is very ‘narrow’.

BT 5.0

We tested BT 5.0 connectivity (claim 45 metres) with a Samsung Galaxy Note9 (with BT5.0). It was 100% reliable to about 30 metres then dropped gradually off. The claim is theoretical under perfect conditions, so it is fair.

GadgetGuy’s take – Ultimate Ears BOOM 3 and MEGABOOM 3

They are not fancy, don’t have 3.5mm AUX, no Wi-Fi or voice assistants – they look good, can handle rough and tumble and sound good too.

If you want the ultimate, take-anywhere speaker, these are it. My personal preference is the MEGABOOM 3 if only for a tad more bass.
