What’s in the Box

The IC-BTS04 comes foam-packaged in a box that weighs approximately 360g (12.6 ounces). Inside the box you will find:

  • The iClever speaker unit
  • A micro-USB charging cable
  • A line out 3.5mm cable
  • A wrist strap
  • A user guide to get you started quickly
  • iClever’s 12-month warranty card (inclusive of a 30-day money back warranty)

iClever IC-BTS04 Design

Despite being a budget wireless speaker, the iClever IC-BTS04 boasts some pretty impressive design features. The first thing that is likely to catch your attention is how slim the unit is, as it is only 28.3mm wide (just over 1 inch). But that does not mean that this iClever speaker is flimsy; instead, it looks compact and gives the overall impression of being suited for outdoor use.

Featuring an attractive cuboid shape, this wireless speaker’s outer casing is framed in durable and lightweight aluminium and has a matte finish that gives it a fashionable and polished appearance. The front section (also made of aluminium) is perforated all over and the sides are slightly indented for a better grip.


The right side panel has a removable cover, which protects the USB and line-out ports from dust, water, and other debris that could otherwise ruin the speaker when used outdoors. As it is the norm with portable speakers, the IC-BTS04 has a set of multi-function buttons on the top panel. These include the power button, play/pause button, multifunctional button, previous track/volume – button, next track/volume + button as well as a microphone to support hands-free calling.

iClever IC-BTS04 Audio

Sound quality is one of the things that will surprise you about this iClever speaker. The IC-BTS04 comes with dual drivers capable of delivering 5 Watts of RMS power each, and as you will quickly notice, it can get pretty loud even without turning the volume all the way up. Static noise was pretty non existent, and distortion was only evident when the volume was set at 100% – but there is no reason whatsoever to do that since sound levels are already on the loud side.

In most cases, decent bass performance requires larger speakers and more potent drivers, but the iClever performs reasonably well on this front. Overall, sound quality is more than adequate for everyday use, whether it is indoors or in open spaces.

iClever IC-BTS04 Battery Life

The iClever IC-BTS04 has a 1,800mAh lithium battery with a low discharge rate. According to the manufacturer, a fully charged battery can provide up to 10 hours of audio playtime. I was able to get between 8.5 – 9.5 hours with the speaker at 80% volume.

On the other hand, a full charge can take up to 4 hours if the battery has been completely drained. This may be somehow inconvenient, but quick-charge features are not usually a part of budget speakers.

iClever IC-BTS04 Connection Options

This portable speaker unit comes with Bluetooth 4.0, which despite not being the latest version does a good job out of providing a solid connection over a maximum range of 33 feet. An HFP profile is there to support hands-free calling, whereas AVRCP technology gives you wider connectivity options, including TVs and hi-fi equipment.

Pairing is pretty much instantaneous and a voice notification will let you know when the device is pairing and once a stable connection has been achieved, which is a nice touch considering that this is a budget speaker. Wired connections are also available via a standard 3.5mm cable, which is included in the box. One-touch NFC is not available.
