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 barbequing 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. However when buying he Bluetooth loudspeaker, make sure the battery life is long enough for what you need. Also remember that the Li-ion batteries used do not like being completely discharged, so charge them up before you use the speaker, and don’t leave it discharged. Also as the batteries get older, so the amount of charge they can store falls.
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. Figures include the top and bottom frequencies that are heard before the response rolls away. Figures like 100 Hz to 20 kHz might be seen. The 100 Hz point is the low frequency and 20 kHz the top frequency. As most of us cannot hear up to 20 kHz, especially as we get older, the top frequency is not quite as important. The low frequency point indicates the level of bass we may expect - the lower it goes the better.
Style: There are very many different styles which are available for Bluetooth speakers. This means that it is possible to choose the style which most suits what you want.
