What to Look For in Bluetooth Headphones

Bluetooth headphones use wireless technology that makes use of low-power radio transmission signals to transmit audio. These signals are converted into analog audio using the built in DACs, and then sent to the headphone drivers for output as sound waves.

Before you can connect your Bluetooth headphones the headphones must be "paired". The pairing process creates a connection between the headset device and parent device.

Audio Quality

Bluetooth transmits audio data via radio waves that are short-range, eliminating the need for cables. It can range up to 30 feet, which is perfect for use around your home. It prevents your music from cutting out when you move between rooms. It also helps keep interference from other Bluetooth devices to a minimum, meaning your headphones won't be flooded with sounds that distract you from the music you're listening to.

However, Bluetooth was not originally designed for audio entertainment and has a small bandwidth that makes it necessary to apply data compression to music files when transmitted wirelessly. This might be acceptable for phone conversations but it affects the quality of your audio experience.

Certain headphones come with aptX audio codecs or aptX HD, which eliminates the need for compression. This results in a much more natural and accurate representation of the original audio file, making it possible 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 satisfy your requirements for listening. If you plan on using your headphones to stream video content from YouTube or Netflix opt for headphones that support aptX Low Latency or aptX HD because these allow the audio to sync up with the video, and provide a more immersive experience.

The Sony WH1000XM5 headphones are among the most efficient Bluetooth headphones with great sound quality. They are worthy winners of our Product of The Year award, and offer a premium audio experience that other headphones can't match. They have a distinct advantage in noise cancellation too and their app experience is among the best in its class. If you're willing more than the Bowers & Wilkins Px7 S2 headphones are another great option with a superior design and impressive audio quality.

Easy of Use

Wireless headphones offer an alternative to corded headphones. Bluetooth is a wireless technology that connects devices such as headphones and music players by using short-range radio waves. When using Bluetooth, a transmitter and receiver must be connected to a source compatible. The source encodes and transmits the audio signal to the Bluetooth chip that then broadcasts it over the radio waves to the headphones.

The headphones' Bluetooth receiver decodes the received signal and transforms it into an audio signal that can be listened. The amplifier in the headphone then amplifies the signal to the appropriate voltage required to drive the speakers and create sound. Most Bluetooth headphones come with digital-to-analog (DAC) converters to ensure high-quality playback.

The most modern Bluetooth headphones will also have a headphone amplifier built-in to boost the output power for louder music playback and to reduce distortion levels. The majority of headphones come with a microphone for hands-free calling and some models also use Apple's proprietary codec aptX, which improves audio quality when streaming movies or podcasts.

Some wireless headphones with best noise cancelling come with internal storage for data, which allows you to store songs and play them without the need of an external audio device. This is ideal for those who prefer to listen to a specific playlist or want to work out. However, updating and transferring songs stored on internal storage will require the use of a cable and, if your musical tastes change, you'll have to change the content.

The Bowers & Wilkins Px7 S2 headphones have been upgraded from their predecessor in 2020 and are now more premium than ever before, yet they offer a comfortable design for long listening sessions, and a neutral and engaging sound that stands out in a highly competitive class. They provide a long-lasting battery and quick charging, and include aptX Adaptive and aptX HD for audiophiles who have devices that be compatible with these high-quality Bluetooth codecs. They are also very affordable, and have a sleek-minimalist look.

Long Battery Life

Long battery life is among the most important features to look for when buying headphones. You want a pair of headphones that can keep you entertained for the length of a flight or daily commute without having to recharge the battery.

Thankfully, the majority of Bluetooth headsets are engineered to deliver on this promise. In fact, the top choices from our reviews include the Cleer Enduro ANC and the Sennheiser Momentum 4 Wireless wireless headphones provide up to 60 hours of playback time per charge. In our testing these headphones proved to be a great price, with top audio quality and a long list of features that are desirable at an affordable price.

The typical pair of Bluetooth headphones will provide a playback time of about 8 hours on one charge. If you're trying to maximize the number of hours you can listen to music before having to plug them back in, it is best to choose one that uses high-efficiency charging technology. These kinds of headsets typically charge in about 1.5 to 2 hours, while standard headsets often require up to three or four times longer for the same amount of juice.

The type of Bluetooth headphones you choose can also have a significant effect on battery life. The two most popular types of Bluetooth headphone are Class 2 and Class 1 headsets. Class 2 headsets typically run on up to 2.5 milliwatts of power, while Class 1 headsets can draw up to 100 mW of power.

Another way to save battery life is by selecting a pair of Bluetooth headsets that are compatible with your mobile device. A majority of smartphones, tablets, and computers support Bluetooth connections So you can easily locate a headset that will work with your device. You can check compatibility with the manufacturer's website or by consulting the manual of your device.

In the early days of Bluetooth headphones connections would slack off frequently and pairing was a pain and audio quality was the musical equivalent of the old tin bottle phones you used to make when you were a child. Thankfully, Bluetooth technology has improved and these wireless headsets provide a superior audio experience and come with a range of features that make your tablet or phone even more useful.

Noise Cancellation

Noise cancelling features are an important feature to look for in Bluetooth headphones. The best noise cancelling headphones will block out ambient noise to allow you to concentrate on your audio without distractions. Noise cancelling technology is built on acoustic isolation which utilizes physical barriers like ear cups or a headset to block out external sound waves. The most advanced headsets isolate the sound from the listener's ear and head using multiple microphones.

Modern headsets and headphones come with noise cancellation. You can control the amount of noise cancellation using the built-in controls, or via an app. Many of them also come with the option to allow users to hear ambient sounds, a feature that's useful when you commute or work in the office.

The Headphone Audio Profile (HSP) is used to convert the digital audio signal transmitted by the Bluetooth transmitter into analog. The HSP codec converts digital signals to an A2DP format. It is then modified on a Bluetooth UHF carrier, and wirelessly transmitted to the headset receiver. The Bluetooth receiver decodes modulation, and then utilizes an integrated DAC to convert the A2DP audio signal back to analog audio. This is then sent wirelessly to the headset's receiver.

The primary distinction between RF headphones and BT is that RF is susceptible to interference from other electromagnetic transmissions, while BT makes use of Bluetooth specific frequencies. The most recent Bluetooth 5.0 protocol has minimized the impact of interference but older models can still be affected by other electronic devices that generate electromagnetic signals in the same frequency range.

Bluetooth-enabled headphones are available in a variety of sizes and styles, such as circumaural, over-ear and on-ear. Some headsets, such as the Jawbone Icon XR and Plantronics Discovery 925, are designed to be a little more discreet, while others, such as the Bose QuietComfort 35 II and noise cancelling headphones TaoTronics SoundLiberty 79, are more flamboyantly styled. The size and shape can be altered based on the function of a headset. Smaller models are more compact and comfortable for long-term wear.
