The earphones are much smaller than headphones, which are over the entire ear, most are no longer wired and, in recent years, have also been noise cancelled. Like most wireless headphones, they use bluetooth technology to connect to sound reproduction equipment such as computers or cell phones. However, do they cancel out the noise for good? What advantages do they have over other similar equipment? To try to answer these questions, we tested three models that are on sale in the Portuguese market and that, according to the brands, are the best they have to offer: the Huawei FreeBuds Pro, the Sony WF-SP800N, and the Samsung Galaxy Buds Pro. Before moving on to the results of this comparison, which we have divided into several parameters, we clarify that these three wireless earphones are not the only ones on the market, nor that this choice automatically makes these three the best in relation to all the others. Brands like Apple, which has the AirPods models, or Sennheiser, which has equipment like Momentum True Wireless 2, offer equally competitive and interesting devices. Even Sony, which in this market is renowned for having the WF-1000XM3, insisted that the best they have on sale are these WF-SP800. For the selection of models, we asked these brands which noise canceling headphones they considered to be the best. As it was not possible for us to test all the devices that are on sale in Portugal, we limited ourselves to these three.
