Bluetooth speakers have started to dominate the market of wireless speakers. In this post I’m going to explain some of the reasons for that and also I’m going to show why the bulk of Bluetooth speakers has fairly poor sound.
There are actually several technologies which are being used for wireless speakers. Bluetooth is merely one of those technologies. Nonetheless, the number of models which are available lately has exploded. That is not surprising given that every portable device has Bluetooth these days. In addition, most devices are able to stream music. Unfortunately, portable devices such as tablets don’t have any space to allow good-quality speakers to be included. As a remedy, most uses prefer using external speakers. In addition to speakers which attach to a tablet or cell phone via cable, many uses prefer using wireless speakers. The speakers don’t usually travel with the user and therefore somebody usually doesn’t want to plug into the cable every time he or she wishes to use speakers. Bluetooth offers a robust wireless connection between the portable device and speakers.
However, most Bluetooth speakers are designed to be portable. That means they are usually fairly small and run from batteries. The small size of Bluetooth speakers is one of the main limitations impeding good audio performance. As an audio engineer, I can attest to the fact that it is extremely difficult to design speakers which can compete with larger speakers in terms of sound quality. However, the portability of Bluetooth speakers is one of the driving factors of those even though the user usually knows that the sound quality is somewhat limited.
Another problem with Bluetooth speakers is the fact that the audio is actually compressed quite a bit whilst being transmitted. Bluetooth does not support streaming of uncompressed audio data. Also, Bluetooth speakers have quite the latency. That issue however has been mitigated lately with the introduction of some low-latency audio codecs which are now employed by Bluetooth.
As an alternative to purchasing Bluetooth speakers while still maintaining Bluetooth wireless connectivity, I would recommend purchasing a wireless amplifier which has built in Bluetooth. This amplifier can be connected to any loudspeaker and will receive music from a portable device as well as amplified to connect to speaker. These amplifiers are available in different sizes and can usually be mounted such that they are out of sight.
I hope that this post has given you an overview of some of the drawbacks that Bluetooth the speakers have. I also have suggested a solution for overcoming some of these drawbacks.
