Now that you’ve gone through our reviews, you should learn more about picking the right product by knowing what important features to look for, which we have detailed in this section.
How does Bluetooth connectivity work?
Bluetooth speakers connect directly or wirelessly to the source of sounds, like mobile phones, tablets, or computers, without needing cables. The paired device(s) and the speaker exchange data through ultra-high frequency radio waves, with a frequency range of up to 2.4GHz.
However, Bluetooth has some limitations. First, it is a short-range means of connectivity and doesn’t work outside a particular range–usually 10 meters. While Bluetooth can transmit signals through walls, the more objects on its path, the lower the range.
Lastly, their sound quality is generally lower than wired speakers as they process sound digitally, which may affect the noise and dynamic range compression.
What specifications to look for in a Bluetooth speaker?
Before buying a Bluetooth speaker, some factors come into play. Some of these factors are the level of sound quality you desire or where you intend to use a Bluetooth speaker.
For instance, size and weight are the top specifications if you want one for the road. Without further ado, let’s get into these top features.
Waterproof
Chances are, your speaker may accidentally fall into the water or you get beat by rain while carrying it, and that’s what makes this feature vital. The IPX rating determines water resistance. Any brand can label its products waterproof, but the IPX rating tells you if it really is.
The IP67 rating is the most commonly used and is exactly what you’re looking for. It implies the device can be in water (one meter deep) for about thirty minutes without damage. Devices of this rating are also dust-resistant. Other IPX ratings to take note of are IPX7 or IP68.
Lightweight and compact
More often than not, people buy Bluetooth speakers to use outdoors. So if that’s the case, you should look for portable and convenient ones to carry around.
Generally, a speaker measuring 15 cm or less is ideal because it fits anywhere, like your backpacks, drawers (for storage), etc. In terms of weight, it should weigh less than 2 lbs, so it feels light in your hands when held.
Sound quality
To determine if the speaker has excellent sound quality, look at the output power, frequency range, sound system, and impedance. The output power should be between 10-30 watts, while the frequency range should be 20Hz to 20kHz. As for impedance, it should range from 2-8 ohms.
Sound system
The arrangement of a sound system plays a significant role in the sound quality delivered. There are different types ranging from 2.1 to 7.1.
The 5.1 surround sound system (five full-range speakers plus one subwoofer for bass) is the most popularly used and produces clearer, more immersive, and richer bass than a 2.1 system (two full-range speakers plus sub) or 2.0 system (two full-range speakers).
7.1 sound systems are more advanced and expensive and are primarily used in professional recording studios.
Impedance
Impedance measures a speaker’s resistance to the current flow and is vital for sound systems to avoid distortion. Bluetooth speakers have impedance ranging from 2-8 ohms. As a rule of thumb, a lower impedance translates to better sound quality.
Battery
Strong battery life is essential to avoid frequent recharges that may eventually damage the battery life. Our top speakers have an average battery life of 10-12 hours on a full charge.
In the same way, the speaker should charge quickly as long charging hours can be pretty annoying and most often don’t equate to long runtimes.
You should bear in mind that the louder the speaker, the more current it will use, and the battery won’t last as long before it needs recharging. Other factors that quickly drain the battery life include wireless connectivity, high volume level, etc.
Connectivity
You can choose to explore other connectivity options besides Bluetooth. Other wireless ways to connect to devices include WiFi, NFC, or AirPlay. WiFi is supported on all devices, but Airplay is only available on apple devices.
As for NFC speakers, they automatically pair with NFC-compatible devices when in close range. Users can also connect through cable inputs such as aux.
Compatibility
The Bluetooth speaker you’re looking at must be compatible with different Bluetooth versions. Newer products are designed to work with the latest Bluetooth versions (5.0 and above), which limits your connectivity options. Hence, to expand your range, you should check if it also works with lower versions like 2.0 to 4.0.
Design
Spherical, rectangular, or whatever shape it is– the most important thing is that the buttons are well-placed for easy access. Soft-touch buttons are also preferred to traditional ones. Apart from the shape, brands also release multiple color combinations to suit different personalities. Lastly, you should check to see what ports are supported.
Extra features for Bluetooth speakers
In addition to the main features, these extra features will improve the overall quality of your user experience.
Hands-free feature
One of the merits of Bluetooth speakers is their built-in mic, allowing users to receive calls in hands-free mode. Additionally, they allow users to interact with the virtual assistant on their phones.
Since the speaker is loud, you can clearly hear who’s on the other line. This feature comes in handy when driving with your speaker on, for instance, but on the other hand, it could lead to disturbance or a privacy issue if the call happens during a party or a public place because everyone will be able to hear the call.
AptX HD and LDAC Support
AptX HD Bluetooth speakers can stream up to 24-bit per 48kHz, while LDAC-supported ones allow high-resolution audio streaming up to 32-bit per 96kHz. Bluetooth 5.0 speakers support these functions.
Built-in charger
This usually comes in the form of a charging stand, which is more convenient than conventional chargers. They also charge faster and will come in handy, particularly outdoors, as you can take them along instead of looking for power outlets to charge your speaker.
Dedicated App
A dedicated Bluetooth app is handy as it enables fast and easy pairing and personalization of settings. Generally, these apps are prone to connectivity issues and bugs, but most past users liked using them.
Durability
A durable device ensures you get the most of your money’s worth. A lot of features contribute to the durability of a Bluetooth speaker, including being dustproof and shockproof. Dustproof speakers prevent dust or debris from clogging their grilles, and the shockproof feature ensures they resist damage from the impact of falling to the ground.
Final words
In this article, we reviewed some of the top Bluetooth speakers, detailing their pros, cons, and most essential features that qualify them to be on our list. That is followed by a buying guide, which explains vital and extra features to look for, such as the battery, sound quality, water resistance, app control, and many more.
