Aukey Waterproof Bluetooth Speaker Review

In terms of design, this has to be the most uniquely shaped Bluetooth speaker I’ve seen in a while. For this model, Aukey has ditched the usual rectangular design that’s common in most portable speakers on the market right now. Finding a nickname for this speaker definitely wasn’t hard, my nephew came up with “the wheel” in about 2 seconds and he’s only 5 years old so fair enough.

The wheel is about 2 inches thick and it’s made from a mixture of rubber, ABS plastic on the back and metal for the front grille and stabilizer – it weighs just under 7 ounces which is ideal considering its purpose as a low profile outdoor speaker.

The top of the speaker features a simple control panel with 3 buttons (along with the built-in microphone), these are used to turn the speaker on/off, skip tracks/adjust volume up and down. As with most wireless speakers, the volume and skip track buttons are multi-functional so you’ll need to long press and short press for your desired function.


All input connection ports are at the back of the speaker under a rubber cap, these include the USB charging port and the AUX port for connections to wired devices. Remember to close this after charging if you’re taking it outside as it’s designed to protect the internal components from water.

3Aukey SK-M4 Audio

Audio quality is something that’s pretty much relative to the price of a speaker – especially those in the budget range. For a 3watt wireless speaker under £10, the SK-M4’s mid-range and high-end are both fairly clean but as expected – it does lack noticeable bass. The overall volume level is adequate for a good individual listening experience but it definitely won’t be enough for a small group or get together.

4Aukey SK-M4 Battery Life

The SK-M4 is fitted with a 700mAh lithium battery which according to the Aukey SK-M4 manual should be able to give you at least 6 hours once fully charged. For me, I was able to get a bit more out of it – just over 7 hours to be exact. Because it’s only a 700mAh battery, it only takes between 2-3 hours to charge the SK-M4 speaker.

5Aukey SK-M4 Connectivity

Connecting to this portable outdoor speaker is pretty simple and straight forward, just turn on the speaker and wait for your phone to detect it then click the “Aukey SK-M4” option on your phone’s list to connect. The SK-M4 uses Bluetooth v2.1 + EDR which despite not being the latest version still provides a very stable connection over the recommended 10m range.

Just for the sake of testing, I’ve even tried it from room to room to see how well it would perform when there are walls between it. I’m pleased to say that despite being a budget Bluetooth speaker, the signal remained stable even with a few obstructions in the way. Not bad for a speaker under £10.
