What to Look For in Bluetooth Headphones
Bluetooth headphones transmit audio by using a wireless technology which utilizes radio transmission signals that have low power. These signals are converted to analog audio by the built-in DACs and then sent to the drivers of the headphones to be outputted as sound waves.
Before you can connect your Bluetooth headphones the headphones must be "paired". The process of pairing establishes an information link between the headset and parent device.
Audio Quality
Bluetooth transmits audio data via short-range radio waves, eliminating the need for cables. It can transmit audio information up 30 feet away, making it ideal for use in your home. This prevents the music from cutting out as you move between rooms. It also helps to keep interference from other Bluetooth devices to a minimum, meaning your headphones won't be overloaded with sounds that distract you from the music you're listening.
Bluetooth was not designed to be used for audio entertainment. Its limited bandwidth forces it to compress music files in order to transmit wirelessly. This is suitable for phone calls, but it will affect the quality of audio.
To combat this, certain headphones come equipped with aptX or aptX HD audio codecs that eliminate the need for compression of data. This creates a more authentic and accurate representation of the original audio file, which allows you to enjoy high-quality music via Bluetooth without loss. Spotify and Apple Music, among others are compatible with these higher-quality Bluetooth codes.
The most reliable Bluetooth headphones will at a minimum support an audio format that is basic like SBC. However there are many that will support more advanced audio formats to meet your needs for listening. If you're planning to use your headphones to stream videos from YouTube or Netflix pick headphones that support aptX Low Latency or aptXHD. This will allow the audio and video to sync, providing the most immersive listening experience.

User-Friendliness
Wireless headphones are a great alternative to corded headphones. Bluetooth is an wireless technology that connects devices such as headphones and music players by using radio waves that are short-range. When using Bluetooth, a transmitter and receiver must be connected to a compatible source. The source encodes and sends the audio signal to the Bluetooth chip, which in turn broadcasts it via radio waves to the headphones.
The headphones' Bluetooth receiver decodes the received signal and transforms it into an analog audio signal that can be listened to. Then, the headphones' audio amplifier brings the signal to a high enough voltage level to drive its speakers, which creates sound. The majority of Bluetooth headphones will have digital-to-analog (DAC) converters to ensure high-quality playback.
Most modern Bluetooth headphones will also have a headphone amplifier built-in to boost the power output for louder music playback and reduce distortion levels. Most headphones have a microphone for hands-free call, and some models support Apple's exclusive codec aptX to enhance the quality of audio when streaming movies or podcasts.
Some wireless headphones have internal data storage that allows users to store music and play them without needing an external audio device. This is ideal for those who like to listen to a particular playlist or want to work out. Transferring and updating music from internal storage requires a cable. If your musical tastes change, then you'll have to replace them.
Bowers & Wilkins' Px7 S2 headphones are higher-end than their predecessors that was released in 2020. They have a neutral, ethereal sound that is lively and stands out amongst the competition. They provide a long-lasting battery as well as fast charging. They also include aptX Adaptive and aptX HD for audiophiles with sources that can be compatible with these high-quality Bluetooth codecs. They are also very affordable, and have a sleek-minimalist design.
Long Battery Life
Long battery life is among the most important features to look for when buying headphones. You want a pair that can keep you entertained for the length of a flight or daily commute without needing to recharge the battery.
The majority of Bluetooth headsets are made to deliver on that promise. The top picks in our ratings, like the Cleer Enduro ANC or the Sennheiser momentum 4 wireless over-ear headphones offer up to 60 hours of playback per charge. In our testing these headphones proved to be a fantastic value, offering premium audio performance and a long list of desirable features for an affordable price.
The typical pair of Bluetooth headphones comes with an average playback time of 8 hours on one charge. If you're seeking to extend the amount of time you can listen before needing to reconnect them, it is best to select one that uses high-efficiency charging technology. These models charge in 1.5 to 2 hours whereas traditional headsets can take up to 3 to 4 times longer to get the same amount.
Additionally, the kind of Bluetooth headset you buy can also have a significant impact in the life of your battery. Class 2 and Class 1 headsets are the two most commonly used kinds. Class 2 headsets typically use up to 2.5 milliwatts of power, while Class 1 headsets can consume up to 100 milliwatts of power.
You can also extend battery life by choosing Bluetooth headsets that are compatible with your mobile phone. There are headphones that work with most smartphones or tablets as well as computers. You can verify compatibility by visiting the website of the manufacturer or looking through the manual for your device for details on how to do this.
In the early days, Bluetooth headphones were a mess. They would constantly drop out and pairing was a hassle and the sound quality was comparable to the old tin-can phones you used to make when you were a kid. Bluetooth technology has advanced and wireless headsets offer a great audio experience, with a range of features to make your smartphone or tablet even more practical.
Noise Cancellation
Look for headphones with noise cancelling capabilities. The most effective noise cancelling headphones substantially reduce background noise which allows you to concentrate on your audio without being distracted by surrounding sounds. Noise cancelling technology is based on acoustic separation, which is the use of physical barriers like ear cups or headsets to block out noise from outside. The most advanced headsets employ multiple microphones to isolate the sound from the listener's ears and head, resulting in earphones headphones highly effective audio quality.
Modern headphones and headsets are equipped with noise cancellation. You can adjust the amount of noise cancellation by using the built-in controls or via an app. Many also include the option of allowing the user to hear ambient sounds which is useful when you commute or work in the office.
The first step in audio transmission is the conversion of the digital audio signal from the Bluetooth transmitter to analog by using the Headphone Audio Profile (HSP). The HSP codec encodes the digital signal into an A2DP format which is then re-modulated onto a Bluetooth UHF carrier wave, and then wirelessly transmitted to the receiver of the headset. The Bluetooth receiver recognizes the modulation and utilizes an integrated DAC to convert the A2DP signal back into an analog audio signal, which is then transmitted to the drivers of the headphones.
The primary distinction between RF headphones and BT is that RF is susceptible to interference from other electromagnetic transmissions, while BT utilizes Bluetooth specific frequencies. The latest Bluetooth 5.0 protocol has reduced the impact of interference however older models may be affected by other electronic devices that emit electromagnetic signals in the same frequency range.
Bluetooth-enabled headphones are available in various styles and sizes, including over-ear, circumaural and on-ear. Some headsets are designed to be discrete such as the Plantronics Discovery 925 and Jawbone Icon XR, while others are more flamboyant, such as the Bose QuietComfort 35 II or TaoTronics soundLiberty 79. The size and shape of a headset can be influenced based on the capabilities of the headset. Smaller models are more compact and comfortable for long-term wear.
