Cellecor Comet CBS-05 Pro

Manufacturer: Cellecor

The Cellecor Comet CBS-05 Pro is a portable speaker designed for straightforward wireless audio use, offering a physical control panel directly on the unit along with a remote control for convenient operation from a distance. It runs on a 4000 mAh rechargeable battery that supports up to 10 hours of continuous playback, and a battery level indicator keeps the user informed of remaining charge. The speaker connects via a detachable cable and includes a USB Type-C port for recharging.

On the connectivity side, the CBS-05 Pro supports Bluetooth 5.3 with a stated range of up to 10 meters, and also provides an AUX input for wired audio sources. It includes an external memory slot for local file playback and features a single USB port. The speaker delivers audio through a 1 x 80W output configuration, while additional touches such as voice prompts and a sleep timer add a degree of functional utility to the overall feature set. It weighs 1270 g with dimensions of 200 x 190 x 190 mm and carries a one-year warranty.

Pros
  • Bluetooth 5.3 ensures a stable wireless connection with a reasonably modern protocol
  • The included remote control allows playback management without needing to approach the unit directly
  • An external memory slot adds a convenient option for playing audio from local storage without a connected device
  • A battery level indicator takes the guesswork out of knowing when a recharge is needed
  • The detachable cable adds a degree of practical flexibility for transport and replacement
  • A sleep timer allows the speaker to power down automatically after a set period
Cons
  • With no water resistance of any kind, the speaker is unsuitable for outdoor or wet environments
  • The 10-meter Bluetooth range is limited, restricting usability across larger spaces
  • No advanced audio codecs such as aptX, LDAC, or AAC are supported, limiting wireless audio transmission options
  • The battery is not removable, so a dead battery means the unit must be charged rather than swapped out
  • Stereo pairing is not supported, so two units cannot be combined for a wider soundstage
  • No microphone is built in, making the speaker unsuitable for hands-free calls or voice interaction
Who is this for?

This speaker suits users who want a straightforward wireless audio setup for indoor use, such as in a living room or bedroom, where the 10-meter Bluetooth range is sufficient. The remote control and on-device control panel make it a practical choice for those who prefer operating their speaker from a fixed position without relying on a smartphone app. The external memory slot and AUX input also make it well-suited to users who want flexible playback options beyond Bluetooth streaming, while the sleep timer adds convenience for those who listen to audio before sleeping.

Who is this NOT for?

Users who need a speaker for outdoor or wet environments will find this unit unsuitable, as it carries no water or dust resistance rating whatsoever. Those who prioritize high-fidelity wireless audio will be limited by the absence of any advanced codec support, including LDAC, aptX, and AAC. The speaker is also a poor fit for anyone looking to use it for hands-free calls or voice assistant interaction, given that it has no built-in microphone, and users who want to fill a large space with sound may find the 10-meter Bluetooth range and lack of stereo pairing restrictive.
