The technology world has already shown us the unlimited advantages of going wireless. Wireless headphones are one of the most popular innovations today. The flexibility of hands-free control and freedom from tangled wires in crowded vehicles is incomparable. Headphones can utilise technologies like Bluetooth or radio frequency (RF) to operate wirelessly. In this article we look at Bluetooth-powered in-ear headphones due to the extensive pervasiveness of the technology today. We have limited our choices to headphones that cost ₹ 4000 or less.
Features of Bluetooth headphones
Bluetooth is an integral feature of smartphones, making it one of the most used media to transmit data wirelessly. Bluetooth headphones work on the same principle. To put it simply, the source device, that is, smartphone, tablet or music system, transmits audio data digitally in the form of a low-power Bluetooth radio signal. The headphones house a Bluetooth module, whose receiver unit receives the signal. A small amplifier inside the headphones strengthens the received signal. The signal is decoded back into audio data and played through the ear pieces. The headphones come with a battery pack to keep it running.
Bluetooth headphones can pair with a single source device at a time. This ensures no interference by other devices during signal transmission. Data is transmitted in a secured connection. Generally, Bluetooth pairing can operate within a range of 10m (30-feet) between the paired devices. The headphones feature various control buttons for easy and quick use, including volume control, connectivity, playlists and more.
Data shared over Bluetooth is usually compressed, which often compromises its quality, especially audio files. However, inclusion of a new technology, called aptX, addresses that challenge well, ensuring modern Bluetooth headphones receive audio quality closest to the original file.
While purchasing a set of headphones, the most essential feature to identify is sound quality. First-hand physical trial of the device is the best way to evaluate it. In addition to sound, other features can also help determine the choice.
Features like higher sound pressure level of, say, 100dB to determine the loudness range of the headphones and higher impedance (not less than 33ohms) to ensure longer life of the device can be reliable factors.
Good bass quality and noise-cancellation features should also be considered. It is important to ensure that the selected headphones have aptX support and a good battery life (at least four hours audio play and 10 hours talk life). Go for a product that comes with a microphone for communication. In addition, a lightweight option can be considered to assure comfortable portability.
