The Venstar S203 is a portable, ruggedized, mostly water-proof bluetooth speaker with a light-wieght carabiner-style clip, for most anyone. The available ports consists of an audio port (3.5mm), micro-USB port and micro-SD card slot. In the box you get a micro USB cord (for charging) and an audio patch cord, perfect for pairing to your phone…if it doesn’t support bluetooth. Which brings up the next obvious point about these speakers, they’re bluetooth enabled (A2DP, HFP, HSP, Support voice prompt). The final really damn cool feature, remote shutter control for yet another selfie option (Sorry Android, iOS only).


The unit is all black. The speaker grills are tiny holes, semi-gloss black paint and the body around the unit is rubberised, flat black. It’s got a solid, durable feel to it and satisfying heft. Five buttons across the top, from left to right: bluetooth pairing/phone answering (Mic and BT light above), back/rev, play/pause, fwd/f-fwd and power (with battery charge indicator lights above). The right side of the device houses the aforementioned ports and carabiner. The left side is bare and the bottom has some device info and a QR code that takes you to the company website for this product.

This very compact unit packs a big punch. In fact, the only thing I don’t like about it is the volume when it starts…it’s loud, 75% of max volume. As long as you remember to keep it charged it seems to remember the last volume just fine. I drained it completely a few times (it takes hours, 9.5 hours for me, several times) on a recent road-trip to Montana. The micro-SD card reads MP3, WAV, WMA, APE and FLAC and it’s a great way to listen to music. It doesn’t give you options though, it just starts at the beginning and goes until it’s out of files. Bluetooth is simple and quick to pair, works with Google Now flawlessly. The sounds gets more than loud enough. You’re not going to power a pool party Florida State with this speaker but it’s ideal for taking camping, hiking or backpacking…something else I did while testing this unit. Not a lot of weight to add to your pack to be able to bring some music along.

Final Thoughts

I’ve had this unit and the Venstar S403 for about a month and have been using them both, a lot. I have to say I like this one just a bit more than it’s big brother. I like the big brother just fine, check out my review for the details. The Venstar S203 is a great speaker, absolutely fantastic for the price. The day I got it, I loaded a microSD card with 75 tracks and used that music for a party we were having at the house. No one knew where the music was coming from, but it filled the entire downstairs.

Like I said, just buy it.
