VTIN Cuber Waterproof Bluetooth Speaker Review

The VTIN Cuber waterproof Bluetooth speaker is a palm size portable speaker with an IP67 waterproof rating, 8 hours battery life and 5W RMS audio output. This is the second VTIN Bluetooth speaker we’ve had in the past week, and after testing the VTIN Punker – expectations are really high for this mini Bluetooth speaker.

1What’s in the Box

The VTIN Cuber waterproof Bluetooth speaker ships in a standard brown cardboard box with a white cardboard sleeve, the sleeve has the image of the speaker on the front and all the main specs and details at the back. As with other VTIN products we’ve reviewed, the products inside always come secure and well padded with foam, contents include:

  • The VTIN Cuber speaker
  • A USB charging cable
  • A 3.5mm audio cable
  • A rubber strap
  • The VTIN Cuber manual

2VTIN Cuber Design

VTIN Cuber SpeakerThe Cuber has a very simplistic yet functional appearance. Its square body measures just 3(W)x3(L)x2.2(D) inches and weighs only 5.5oz, this allows the Cuber to fit neatly in the palm of your hands.

Most of the speaker enclosure is made from silicon except for the front grille which is fitted with a fine aluminium mesh, this gives the speaker a very smooth rubbery feeling that’s pleasant to touch.

The front grille and back panel both have the VTIN logo stamped on them and the top right corner has a triangular cutout to insert the included rubber strap.

The 4 control buttons are all located on top of the speaker, these include the volume up/skip forward button, the volume down/previous track button, the play/pause/answer calls button and the power button.

The 2 input ports (AUX and charging) are on the left panel neatly tucked under a protective silicone cap. Apart from the blue review sample we received, there’s also an orange version and a black version for those who want to mix things up a bit.

The designers of the Cuber set out to develop a product that’s powerful, easy to transport, has a very small footprint and able to withstand anything the weather throws at it. The results were spot on.

3VTIN Cuber Audio

Audio playback from the Cuber is very well balanced, vocals are very clean even when used at 100% volume, but as expected from such a small device – there’s not a lot of bass.  In terms of volume, the Cuber does get fairly loud for a palm size speaker.

There’s a 5W driver under hood and having used quite a few 5W speakers in the past, this one definitely sounds a lot louder and crisper than other cheaper models. I’ve been using this mainly as a shower speaker for the past few days and when used in an enclosed shower cubicle it sounds a lot louder than you’d expect.

4VTIN Cuber Battery Life

A quick glance through the Cuber’s manual shows that the speaker has a built-in 800mAh rechargeable battery which should give a very respectable 8 hours playback time. This was slightly off for me, using the speaker at 60% volume – I got 7 hours 34 minutes from a full charge cycle. Not bad considering this speaker fits in your palm.

5VTIN Cuber Connectivity

The Cuber features Bluetooth 4.0 by CSR, this improved version provides a well deserved boost in connectivity and stability not to mention it’s a lot more energy efficient than previous versions. Pairing takes about 4-5 seconds, my Samsung Galaxy S6 picked up the signal immediately after switching the speaker on and it also reconnects automatically for future use.

Being a waterproof speaker designed for outdoor use, I don’t think many people will be using the 3.5mm audio jack but nonetheless this is an option that worked straight out the box without any problems.
