The Rockville Rock Everywhere is a true wireless stereo (TWS) Bluetooth speaker that you will want to bring with you everywhere you go because it sounds so good!
Audiophile Sound Quality
The ROCK EVERYWHERE is a larger version of our famous ROCK ANYWHERE speaker. This model has a bigger battery, and even bigger sound! The passive radiator give this booming bass while the full range speakers give you loud and clear mids and highs. This speaker is loud enough to use outdoors and sounds clear enough for use in your bedroom or even in your restaurant. What makes this speaker special is that at high volume levels the sound is still extremely clear.
TWS – True Wireless Stereo
The TWS function allows you to wirelessly connect 2 of these speakers together to give you stereo sound. This will give you a left and right channel which translates into true stereo surround sound. If you want amazing sound in your bedroom you can just put one of these on each side of your room and it will sound like you have a full surround sound speaker system!
We use an advanced Bluetooth chip called the Actions 4.2 that has a dual core single chip with a DSP that we tuned to increase the sound quality. The advantage of this Bluetooth chip is that you get way better battery life, better sound, and better Bluetooth distance.
The ROCK EVEYWHERE is 100% waterproof. You can take it with you into the shower or pour water all over it for fun and it will not get damaged. You can even submerge it in water for around 20 seconds without damage.
Built in phone charging (powerbank)
This model has a built in powerbank that will allow you to charge your phone or other USB device.
Battery lasts extremely long!
This will go for 47 hours at 25 % volume, 27 hours at 50 % volume, and 5 hours at max volume. This item also has 3 LED lights to indicate how much battery you have left.
Tons of playback options
In addition to Bluetooth this speaker plays back songs on a memory card (up to 256gB). There is also a 3.5MM aux input so you can plug in any other audio device.
Mount it everywhere you go!
We include a bar clamp and a rubber strap in the box. This means you can hang it on your backpack, hang it on a fence, mount it to the handlebar of your bike, hang it from your showerhead, and more. The hanging, clamping, and desktop options make this speaker more useful than any other on the market.
90 Day Money Back Guarantee
We guarantee this will sound clearer than any other portable Bluetooth speaker on the market. Even those at double the price! We offer a 90 day money back guarantee.
