Listening to music or watching a movie has a completely different effect with a pair of headphones, especially if wireless (with wireless technology). Thanks to the absence of the wire we will no longer be tied to staying close to the PC or TV, we will be able to listen to anything without disturbing those in the house or the neighborhood, enjoying a higher quality sound than the simple speakers or speakers integrated in the TV or connected to PC. But how to choose quality wireless headphones without making mistakes "> How to improve the sound of wireless headphones (PC and smartphone)
How to choose wireless headphones
In order to choose the correct wireless headphones model we will have to take a look at the technical characteristics.Since the parameters can be numerous, here are the ones to consider when choosing a pair of wireless headphones.
- Wireless technology used: the wireless technology used is important in order to connect the selected headphones to the playback device without problems. The most used technology is undoubtedly Bluetooth, which allows you to connect headphones to any modern smartphone or tablet, to the PC (via Bluetooth adapter) and on some TVs equipped with Bluetooth technology. Alternatively, RF (Radio Frequencies) are used, often associated with an independent transmission base to be connected to the TV or playback device via audio jack cable or optical audio cable. WiFi Direct can also be used as a transmission system, but it is not widespread and will not be taken into consideration.
- Wireless signal coverage : this parameter depends directly on the type of wireless technology adopted and the listening distance. If the headphones chosen adopt Bluetooth technology, we will obtain maximum quality and absence of interference within the first 3-4 meters, with the signal that decays rapidly after 5 meters (especially in the presence of obstacles or other wireless waves). So Bluetooth headphones are excellent if used close enough to the source, while they may not be usable over medium distances (like TV-sofa, where 10 meters away can make a difference). Headphones that use radio frequencies (RF) certainly have greater coverage with the best results obtainable up to 15 meters, but particularly suffer from interference with other radio wave devices (FM stereo, clock radio, home alarms, automatic gate remote control etc.) .), so the audio quality may not be perfect even if we are close enough (we may hear interference like when we listen to the disturbed FM radio). To solve these types of problems, RF wireless headphones often offer multiple tuning channels, so you can independently choose the best interference-free channel.
- Transmission security : the Bluetooth connection is encrypted, therefore no one else will be able to listen to what we are transmitting to the headphones (except in the case in which it decides to also connect to the same source). The radio connection is instead in the clear, so (from a theoretical point of view) anyone can pick up the radio frequency that we are using for headphones and listen to everything we are transmitting.
It is not uncommon to "intercept" other radio broadcasts as well, which will be played by the headphones disturbing listening. If this parameter may not be important in most scenarios, it could become so if we live in an area where radio waves are often used to communicate or control vehicles remotely (radio stations for radio amateurs, airplane model runways, military or air force barracks etc.).
- Systems to improve the audio: the more expensive models of wireless headphones allow to obtain a higher quality while listening using independent equalizers, supporting proprietary audio compression protocols (APT-X, AAC, CSR or A2DP) or by mounting a chip dedicated to audio conversion (DAC). The models with these features offer crystal clear, clean audio with powerful volumes at any listening frequency, for a truly unique experience.
- Usage scenario: it is not said that the most expensive headphones are good for all usage scenarios! For example, if we are looking for wireless headphones to listen to TV in the living room without disturbing, the best solution is radio wave (RF) headphones, comfortable to configure and with good quality (without interference). If instead we want to use wireless headphones on the PC or smartphone / tablet, the best choice is without a doubt the Bluetooth headphones, which offer maximum quality in the short distance and can also improve the quality of the audio thanks to the integrated improvements on high-end models.
