What’s in the box

The iClever IC-BTS03 Bluetooth speaker is presented in a rather plain-looking brown box that keeps shipping weight under 0.8lb. Open the box to find the actual speaker unit, a “Getting Started” leaflet and two cables (one standard USB and one 3.5mm) that you will need to charge the device and to connect it to non-Bluetooth-enabled devices. A warranty card is also included.

iClever IC-BTS03 Bluetooth Speaker Design

The IC-BTS03 has been primarily designed to be used outdoors or as a shower speaker, so rugged and compact design are its key design characteristics. Shaped like a flat cube and measuring only 3.89 x 2.3 x 3.89 inches (smaller than a coffee mug), the IC-BTS03 ticks all the boxes when it comes to portability and convenience.

There are other factors adding to the fantastic portability of this Bluetooth speaker. A waterproof wrist strap is attached to one of the corners, making it easier to take the speaker with you everywhere.

The casing has been made using a hard but lightweight and waterproof plastic material that keeps its total weight to just over 10 ounces (286 grams). All four corners have been given rounded and texturised edges for extra balance and stability. These also provide a shock-proof enclosure that will keep the speaker protected should you drop it.

In addition to its obvious sturdiness, the IC-BTS03 combines functionality with attractive design thanks to details like a modern black and orange colour scheme and a user-friendly set of four buttons placed on top of the main unit for quick pairing, volume and track controls. The IC-BTS03 also has built-in redial and speakerphone functions so you can make and take calls without touching your mobile phone – very useful if you’re using it as a shower speaker.

iClever IC-BTS03 Audio and Battery Life

Audio quality is in line with what you would expect from a budget Bluetooth speaker. The iClever IC-BTS03 is fitted with a single driver that delivers a total audio output of 5 Watts and while it does some bass to it, don’t expect this to shake your walls anytime soon. Audio clarity on the other hand is exceptional, classical music and even hands-free calls are very detailed even if it’s set at 100% volume.

An above-average battery life is another key features of this iClever Bluetooth speaker. Powered by a rechargeable 2,000mAh lithium-ion battery, this device is able to keep playing your favourite tunes for up to 10 hours once it’s fully charged. I got 10hours 14minutes during my initial test and was pretty chuffed with that.

Charging takes place via a standard USB port and the speaker comes with a partial charge so you can enjoy its audio performance for several hours right out of the box. There is also an automatic battery saving function that will turn the speaker off if it hasn’t been used for 10 minutes or if you disconnect it from the audio source.

iClever IC-BTS03 Connection Options

Connectivity between Bluetooth devices and this iClever speaker is smooth and reliable thanks to a Bluetooth 3.1 +EDR profile, which ensures fast data transfers, faster pairing and reduced battery consumption as opposed to the older versions.

According to the manufacturer, maximum range on an open field is 33 feet. During my initial test, the connection between my iPhone and the IC-BTS03 held up strong over a 30-feet range and once indoors it kept playing without stuttering at a distance of 25 feet. I’ve even used it to played music from room to room without any problems.

Wired connectivity with older or non-Bluetooth devices is also available via a 3.5mm port (AUX cable is provided). As normal, this works perfectly without any fuss.
