20 Things You Need To Know About Bluetooth Headphones
What to Look For in Bluetooth Headphones


Bluetooth headphones utilize wireless technology that utilizes low power radio transmission signals to send audio. These signals are converted to analog audio by the built-in DACs and then transmitted to the drivers of the headphones for output as sound waves.

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

Audio Quality

Bluetooth transmits audio data using radio waves that are short-range, eliminating the necessity for cables. It has a range of up to 30 feet which is perfect for use in your home and prevents your music from cutting out as you move between rooms. It also helps keep interference from other Bluetooth-enabled devices at the minimum, ensuring that your headphones aren't overloaded with noises that can distract you from enjoying the music.

However, Bluetooth was not originally designed to be used for audio entertainment. It has a limit on bandwidth that forces it to compress data for music files when they are transmitted wirelessly. This may be fine 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 necessity of compression. This results in a much more natural and accurate representation of the original audio file, allowing you to enjoy high-quality music over Bluetooth without loss. These higher-quality Bluetooth codecs are supported by a wide range of audio applications and music services, including Spotify and Apple Music.

The best bluetooth headphones will work with at the very least an audio codec that is basic, such as SBC, but many will offer more advanced audio codecs that ensure compatibility with all your listening requirements. 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, giving the most immersive listening experience.

The Sony WH1000XM5 headphones are the best Bluetooth headphones for excellent sound quality. They are worthy winners of our Product of The Year award, and offer a premium sound experience that rivals cannot match. The noise cancellation is also superior and the user experience is excellent. Bowers & Wilkins' Px7 S2 headphones offer a superior audio quality and a better design if you're willing to spend more.

Easy of Use

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

When the signal is received, it is decoded by the headphones' Bluetooth receiver and converted into an analog audio signal that can be listened to. Then, the headphone's audio amplifier amplifies the signal to a sufficient voltage level to drive its speakers, thereby generating sound. The majority of headphones using Bluetooth include digital-to-analog conversions (DACs) to ensure high-quality audio playback.

Most modern Bluetooth headphones also come with an integrated headphone amplifier to boost the output power for a more powerful music playback and to reduce distortion levels. Most headphones have an integrated microphone that allows hands-free calls and some models also use Apple's proprietary codec aptX, which improves audio quality when streaming films or podcasts.

Some wireless headphones have internal data storage, which allows you to store a few gigabytes of songs for easy playback without the requirement of an external audio device or a connection. This is great for people who prefer to listen to a certain playlist or want to be untethered when working out. However, transferring and updating songs stored on internal storage will require the use of cables, and if your musical preferences change, you'll need to replace the music.

The Bowers & Wilkins Px7 S2 headphones have been upgraded from their predecessor in 2020 and are now more premium than ever before, but they still provide a comfortable fit for long listening sessions, and a neutral and engaging sound that is distinctive in a class. They deliver impressive battery life and fast charging, and support aptX Adaptive and aptX HD for audiophiles with sources that support these higher-quality Bluetooth codecs. They are also very affordable and sport a sleek minimalist design.

Long Battery Life

When purchasing headphones, the battery's longevity is one of the most important characteristics to look for. You want a pair of headphones that can keep you entertained for the duration of a flight or weekly commutes without having to recharge the battery.

Thankfully, most Bluetooth headsets are engineered to meet this promise. The top picks in our evaluations, such as the Cleer Enduro ANC or the Sennheiser momentum 4 wireless headphones, offer up to 60 hours per charge. In our testing the headphones proved to be an excellent price, with top audio quality and a long list of desirable features for the price of a reasonable amount.

The average pair of Bluetooth headphones will provide the ability to playback for around 8 hours on a single charge. If you're looking to get the most of your headphones, you should opt for a model that offers high-efficiency charging. These kinds of headsets typically charge in 1.5 to 2 hours, while standard headsets often require up to three or four times longer for the same amount of juice.

The kind of Bluetooth headphones you choose can also have a major impact on battery life. Class 2 and Class 1 headsets are the two most popular types. Class 2 headsets can use a maximum power of 2.5 milliwatts, whereas Class 1 headsets can be powered by up 100mW.

Another way you can reduce the time spent on your battery by selecting a pair of Bluetooth headsets that work with your mobile device. A majority of phones, tablets and computers are able to use Bluetooth connections and you'll be able to locate a headset that will work with your device. You can verify compatibility with the manufacturer's website or by looking through the documentation of your device.

In the beginning, Bluetooth headphones were a mess. They would constantly drop out and pairing was a hassle and the sound quality was like the old tin-can telephones that you made when you were a kid. Thankfully, Bluetooth technology has improved and wireless headsets provide a superior audio experience, while also offering many features that make your smartphone or tablet even more efficient.

Noise Cancellation

Noise cancelling capabilities are a crucial feature to look for in bluetooth headphones. The top noise cancelling headphones substantially reduce background noise which allows you to concentrate on your music without being distracted by the sounds around you. Noise cancelling technology is based on acoustic isolators, which utilizes a physical barrier such as ear cups or a headset to block out sound waves. The most advanced headsets block the sound from the listener's ear and head with multiple microphones.

Modern headsets and headphones are equipped with noise cancellation. You can adjust the amount of noise cancellation by using the built-in controls, or an app. Many of them also come with the option of allowing users to hear ambient sounds which is useful when commuting or for working 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. Then, it is modified on the Bluetooth UHF carrier and wirelessly sent to the headset receiver. The Bluetooth receiver decodes modulation, and then utilizes an integrated DAC in order to convert the A2DP audio signal back into analog audio. The converted signal is then transmitted wirelessly to the headset's receiver.

The main distinction between RF headphones and BT is that RF can be affected by other electromagnetic transmissions whereas BT makes use of Bluetooth specific frequencies. The latest Bluetooth 5.0 protocol has reduced the impact of interference but older models can still be affected by other electronic devices that emit electromagnetic signals within the same frequency range.

Bluetooth-enabled headphones come in a variety of sizes and styles, such as circumaural, over-ear and on-ear. Some headsets are designed to be discreet like the Plantronics Discovery 925 and Jawbone Icon XR however, others are more flamboyant, such as the Bose QuietComfort 35 II or TaoTronics soundLiberty 79. The size and shape of a headset can be altered based on the functionality of a headset. Smaller models are more compact and comfortable for long-term wear.
