The first stage in picking the best Bluetooth speaker to buy is to decide exactly what you want to use it for. Some speakers may be for use on the home - others may be for outside, listing when you are BBQ outside, etc., others may be a portable speaker for when you are travelling.
Before you can decide on the best speaker for you, its necessary to determine what it is wanted for. The best buy Bluetooth speaker for the home, may not be the best for travelling, as the requirements will be totally different.
There are several points to consider when buying a Bluetooth speaker:
Battery life: Battery life is a key parameter to consider. You don’t want to be recharging the speaker every hour. It should be able to last as long as you expect to need it. The small speakers tend to have smaller batteries and don’t last as long, but some of the larger ones can expect to last for 24 hours! More typical lengths of operation may be four to ten hours, and it will be specified as average battery life. The reason for this is that the louder you play the speaker, the more current it will use and the battery won’t last as long before it needs recharging.
Audio quality: Obviously it is nice to have a Bluetooth speaker that sounds goo. Often they give specifications for total harmonic distortion and below 1% is a good aim. The lower the better. Some speakers will not give a specification for this, so you may want to listen to it. Also the frequency response is very important. Some speakers sound better than others and this is often as a result of a much better frequency response.
Size: Bluetooth speakers come in a variety of sizes. There are the small conical or cylindrical types aimed at very portable operation and for packing into luggage, and larger ones that tend to provide better quality audio. These may be rectangular or even again cylindrical. Generally the larger they are the better the audio quality, and the larger ones can have a larger battery for longer use.
Audio power: Not all Bluetooth speakers have this parameter specified. When it is stated, it is given in watts. Ten watts is loud, although the efficiency of the speakers in such a small case means they will not be very efficient. Be aware that more power is needed for large rooms and for use outside.
