Bluetooth speakers are convenient and wireless speakers that give you the freedom of getting your own songs and other sounds with you anywhere. They provide the benefit for you to play your own songs in any location of your choosing, be it your room or a garden without having to deal with cables or basic connections.

Looking to buy the best Bluetooth speakers under $100 in USA? Then you arrive at the right place at the perfect time. We always look forward to higher prices when it comes to buying a Bluetooth speaker. While searching for the speakers we came across many speakers which confuse us. So to make the things easier, we have made a list of Things to consider while buying a Bluetooth speaker.

• Frequency response

Frequency response is calculated in Hertz and is commonly described as a variety, say from 100Hz - 20,000Hz. Theoretically, the broader the range, the better the ability of the speaker to reproduce audio as it was designed. However, having a big range alone doesn’t guarantee excellent sound as it depends on how your ear interprets sound too, which can vary wildly from person to person.

• Bluetooth version

The distance and quality of audio transmission depends on the version of Bluetooth which determines how much distance you can keep between your phone and the speaker. You should preferably look for Bluetooth 4 or better, as this edition adds support for Low Energy profile, for better battery life and it is about 60 metres. The data transmission rate and range is improved in the upgraded version; Bluetooth 5, but there’s still time before we see speakers adopting this standard.

• Drivers

The driver is the heart of any speaker.  So it’s crucial you get a proper sized driver. Most portable speakers will normally have a 40mm driver, which is a good size to start with. If you want bigger drivers then expect the overall size of the speaker to increase too.

• Battery Power 

If you're planning to move your speaker from room to room, out in the garden, or even travelling with you, look for a lightweight model that can run on sometimes without battery. The best can last more than 15 hours without having a recharge.

• Charging style

Having an ordinary USB charging slot is an added comfort, especially when you’re outside or at a friend’s house and don’t have the included wire with you. Nowadays most speakers able to connect to a Micro-USB port, so with power banks it is possible to charge them too, if you’re away from a wall socket.

• Wi-Fi

While Bluetooth has made up a lot of ground in wireless audio, Wi-Fi is still excellent in some ways. At its best, for your speaker Wi-Fi streaming can offer lots of services and functions, as well as receiving audio from multiple sources. For higher resolution audio transmission Wi-Fi also allows than Bluetooth, making it ideal for those looking for a top quality speaker to play-back high-resolution audio files. It’s also recommended if you don’t want your music to be disturbed by mobile notifications.

• Portability

When it comes to portability, there’s move-it-around-the-kitchen portable, and then there’s take-it-to-the-top-of-Mount-Everest portable. While there are speakers on keychains these days, obviously, the smaller you go, the more sound will suffer.

Other functions to look out for is if there’s any companion app support, which is useful if you need to manage multiple speakers, check the speaker's battery, or simply to upgrade the speaker’s firmware. If you pay attention to lot high-resolution audio files then it helps to have high-resolution audio profile support.

Another useful feature to have is the assistance for coupling several speakers together for larger sound. Sometimes, one speaker isn’t noisy enough to equally cover a big space or if you’re outside, which is where coupling two or more of the same type of speaker is an advantage. 

Though Bluetooth speakers were an expensive business quite a while ago, things have reduced a bit in past few months, due to more newcomers getting ground with discounts and promotions, plunging a few big names into the game as well. Bluetooth is a short-range wireless communication that is both effective and energy-efficient. Choose the best and buy the best. Enjoy your music on the go.
