Photive CYREN Portable Wireless Bluetooth Speaker Review

Portable wireless Bluetooth speakers became quite popular over the past couple of years, mostly because of the exploding popularity of smartphones and tablets, which finally gave people the freedom to do any computer tasks on the go without the fuss of using a laptop.

If you’re looking for a compact, affordable wireless speaker that provides a loud and clean sound, Photive has got you covered. Their CYREN portable speaker comes with all the features you might need and high quality hardware that will satisfy any user.

Compact housing, high quality sound

The Photive CYREN portable wireless Bluetooth speaker is not the smallest audio box you can find, but it strikes a perfect balance between portability and function. The speaker measures in at 6.5 x 1.5 x 2.4 inches and weighs 12.8 ounces – it almost fits in the palm of your hand, and you’ll definitely have no issues carrying it in a backpack or travel bag.

The best part is that the CYREN does not sacrifice audio quality for the sake of compactness – the device has two 40mm speakers and a built-in passive woofer that provide a total of 6 Watts of power (RMS). That might not seem like much, but it is more than enough to fill any room with sound, or be used outdoors by a small group of people. More importantly, the sound is rich and clean even at maximum volume.

Long range and long battery life

Photive’s CYREN uses Bluetooth 3.0 for its wireless connection – an ubiquitous standard by now, which means you can connect practically any device that can output sound, from mp3 players to smartphones, tablets and laptops. The v3.0 standard uses very little power, and provides an effective range of up to 30 feet indoors – and even better outdoors.

The wireless speaker has a built in Li-Ion battery that is rated for up to 10 hours of continuous playback at medium volume via Bluetooth, and if you use a cable connection, it should last even longer. That can easily get you through a day, but if you run out of juice, you can always recharge the device from a standard USB port, while still being able to listen to your music.

Bluetooth and wired for any application

The Photive CYREN portable wireless Bluetooth speaker supports a standard 1/8” jack input, as well. Bluetooth pairing is quick and easy – there is no PIN, you just tell your device to pair with the CYREN and wait a couple of seconds – that’s it! You can use the CYREN as a stereo speaker for music, as well as for hands free or conference calls, thanks to the built in microphone with noise cancellation and a pretty decent range.

The device itself features several buttons for controlling your audio – on the top, you can find the track, volume and phone call controls, while the back side has the on/off switch (alongside the micro USB port and 1/8” audio jack).

Great features, several colors and accessories at a low price

The Photive CYREN portable wireless Bluetooth speaker offers everything you may want from a compact audio box, and you can choose from several color variations – black, blue, orange, purple or red – if you want to get a more personalized product.

The device retails for under $30 and comes with a micro USB cable, travel charger, 1/8”-1/8” 3ft cable, as well as a nylon carrying bag that will protect it from the elements or damage.

The CYREN is a perfect choice if you need an affordable, small wireless stereo speaker that provides high quality sound and a long battery life.
