Have you ever wondered for how long a Bluetooth receiver works before losing all of the battery power? For some people, this aspect is not so important at first. But this all changes once they have a unit that turns off after every hour, getting to understand the importance of this factor. After all, it is not very convenient to recharge it ten times per day, wasting time that you could have used to listen to your favorite music. However, you should know that most products have a good battery life, which will save you from the need to recharge them every hour. Therefore, take into account this aspect and choose a unit that boasts a long battery life.
One of the most important factor to consider when purchasing such a device is compatibility. You have to check the products and see if the Bluetooth is compatible with the smartphone and the operating system running on the smartphone. Moreover, if it’s a new product, you have to check and see what version of Bluetooth is installed on their smartphones. For example, if it’s a new item, it may have the 4.0 version which will not work on the other old smartphones. However, keep in mind that for some products that provide spotty connectivity, it’s a good idea to check the Bluetooth compatibility. Plus, it’s recommended to check user reviews to make sure that there is not a problem.
One of the most important aspects of a device is the number of watts. Nowadays, when it comes to power, most people are looking for big numbers, since it is commonly assumed that power means more watts and, therefore, better sound. Manufacturers already know this thing, so they are trying to find various ways, in order to achieve the numbers that are looking good to buyers by making tests less stressful. You should also know that a lower quality Bluetooth receiver might claim to output 100 watts per channel in stereo mode. Actually, this will show you that one amp’s power will be split up amongst several speakers, and that will usually result in poor power availability when you will need it most.
Warranty is another important thing you need to consider before purchasing such a device. This is an oral or written statement about the quality, ability, and performance of a product. The longer the term of the warranty, the more confident the manufacturer will be that some problems won’t occur in the time specified. In fact, warranties are some sort of proofs that assure the customers they are making the best decision possible. However, it’s very important to know that most manufacturers offer a 1-year warranty.
If you are thinking about buying a unit which is water-resistant, you will make the wisest decision ever. There are many waterproof models on the market, so it won’t be very difficult to find a quality product. You can stream music while you are on a beach or you are showering.

The SNR is the difference in decibels between the background noise and the received signal. A device is able to receive a signal of -75 dBm and the noise floor is -90 dBm. This means that the SNR is 15 dB. Plus, the quality of the signal can be judged by its SNR. As such, an SNR which features a value of 20 dB is advisable for data networks, while an SNR value of 25 dB is more recommended for networks that are using voice applications.
The frequency response is the quantitative measure of the output of a device in response to a stimulus. The frequency level of these types of products usually has a range of 20 Hz to 20 kHz, so if the frequency level of your device falls somewhere in between 40 HZ to 20k HZ, then it may be one worth having! However, in simple terms, at 20 Hz, an input signal level is able to produce around 100 dB of output. The Frequency Response is usually used to announce you how far from each other should you put the two units, in order to enjoy the high definition sound quality you have been meaning to.
First, you need to know that a device’s impedance means how much load it represents to a time-varying audio signal. This is a complicated measurement because the voltage and current waveforms should be examined. However, the output impedance is measured in ohms and it determines the load that a circuit can drive and the output level which is delivered to the next stage.
The Bluetooth profile is a wireless interface specification used for communication between devices. There are plenty of profiles and each profile specification contains information, including the dependencies on other profiles, the suggested user interface formats and the specific parts of the Bluetooth protocol stack which was used by the profile. However, most products have A2DP (Advanced Audio Distribution Profile) and AVRCP (Audio/Video Remote Control Profile). For example, A2DP defines how high-quality audio can be streamed from one unit to another over a Bluetooth connection. On the other hand, AVRCP provides a standard interface, in order to control Hi-fi equipment, TVs and more. By using a single remote control, the user can control all of the A/V equipment.
Have you ever wondered what is the range of Bluetooth receivers? Bluetooth is designed to use very low power, so the transmission range will be 10 meters which it means about 30 feet. On the other hand, the devices which are using high power will enable ranges up to 100 meters (300 ft.). However, it’s important to know that even the 10 meters range is right for the purposes Bluetooth is intended for.
As you probably know the power ratings are an important indicator of a receiver’s capability. However, they don’t let you know the whole story about the sound quality. The total harmonic distortion rating is a valuable indicator that provides information about the sound signal that the receiver amplifies. When the THD is less than 0.1 percent is not good. The specialists considered the sound is inaudible. On the other hand, when the total harmonic distortion is 0.08 percent and even lower it is considered to be very good. If the THD is higher than 0.1, the wattage ratings are overblown and that will be a big problem.
