Going outdoor on the weekend? It will be awesome just to think about it: hiking, biking, jogging, or picnicking among the green forest or next to the blue ocean. But do you know what makes outdooring more awesome? Music! Today we are going to introduce HV-KB533BT, a portable outdoor Bluetooth speaker that makes your outdoor activities even more danceable.
Appearance
The HV-KB533BT Portable Outdoor Bluetooth Speaker comes with a military style of look as a sign of waterproof functionality. The exterior of the Bluetooth speaker is made of rubber and metal, which combine the flexibility and durability.
There’s a rubber band attached on the Bluetooth speaker, which allows you to attach to your belongings like your bags, bikes, belt etc., so that you can carry the Bluetooth speaker around hand-free.

It is approximately the size of your palm, so you can easily hold it with one hand. Though it is not a big speaker, it provides amazing sound volume (more on that later). 
The HV-KB533BT Portable Outdoor Bluetooth Speaker comes with a USB cable and a 3.5mm port AUX cable, but the USB port and AUX port are well hidden for waterproofing reason. Actually they are hidden under rubber plate says “AUX USB Charge”. [caption id="attachment_7576" align="alignnone" width="500"]

Bike Mounting
It is easy to notice that under the HV-KB533BT Bluetooth speaker there’s a screw hole, which is about 20mm in diameter. This is the screw hole for HV-CH056 Bicycle Mount, which can be attached to the handlebar of your bike. And if you have a tripod that comes in similar size, you can also attach the speaker to it.

Making Calls
There is a built-in mic inside the HV-KB533BT Portable Outdoor Bluetooth Speaker, so you can answer phone calls with the speaker. And if you wish to, you can even put on the speaker and have phone conference along with your friends.Waterproofing
The HV-KB533BT Portable Outdoor Bluetooth Speaker is IPX5 waterproofing, which means it should be able to stand water splash and spray, so it is good enough for heavy sweat, or a sudden sprinkle. However, it cannot be soaked completely into the water, so you should not go diving with it, as it is not designed for diving.Sound Volume
The HV-KB533BT Portable Outdoor Bluetooth Speaker is a 3W speaker, and as most portable speakers out there that have similar size are only 2W or less, you can expect a higher than average volume. I have tried the speaker, and turned it to the maximum volume, and I didn’t notice any noise caused by the volume, instead I was blasted by the decibels. Most of other Bluetooth speakers of similar size have trouble being heard outdoor, as there are more noise in the outdoor than indoor. However, I have tried the HV-KB533BT Portable Outdoor Bluetooth Speaker indoor and outdoor, and I find it can easier overcome most of the environmental noises and can be heard clearly. The maximum volume of the speaker in my opinion is approximately three to four times of the maximum volume of most cellphone, but it is not as loud as a “boom box”. If you are looking for a more powerful speaker, please consider the HV-SK159BT Multi-Functional Wired / Bluetooth Speaker, which provides 10W output power.Battery Life
The HV-KB533BT Portable Outdoor Bluetooth Speaker provides a battery capacity of 1500mAh, allowing a continuous playback of 5 to 8 hours, which should be enough for a day’s activity. But if you are looking for a speaker with bigger battery, you may want to check out HV-SK159BT Multi-Functional Wired / Bluetooth Speaker, which provides 6000 mAh of power, and can be used as a power bank.Conclusion
The HV-KB533BT Portable Outdoor Bluetooth Speaker is a small yet powerful outdoor speaker with bike mounting and waterproofing functionalities. It is ideal for outdooring with a small group of people like your families or your friends while you want your music to come with you wherever you go. If you want a small outdoor speaker with great volume, then the HV-KB533BT Bluetooth speaker is for you; but if you would like a bigger output and bigger battery and don’t mind the size, then you may want to choose bigger speaker like the HV-SK159BT Multi-Functional Wired / Bluetooth Speaker.
