With more and more manufacturers removing the standard audio connectivity from their phones, the 3.5mm headphone jack is slowly, but surely, becoming a figment of imagination!
Without a 3.5mm headphone jack on a phone, the only alternative to listen to music (other than on loudspeaker) it's with a pair of bluetooth headphones or fully wireless earbuds like the QCY T2C, which are super lightweight (4.6 grams) true wireless stereo (TWS) in-ears without wires!
The QCY T2C are canal-type earphones so they don't rest outside the ear canal like earbuds do. The advantage with in-ear headphones is that audio is directly blasting into your eardrums and you get a better bass response.
The QCY T2C have a comfortable fit and they are fairly secure, thanks to the angled nozzles, which has a thermoplastic matte finish, just like the rest of the body. On the front of the earpieces, you get a large multi-functional button with a built-in led indicator to indicate pairing and charging.
The QCY T2C have an IPX4 waterproof rating so, they are technically sweat resistant but if you are someone who sweats buckets, it's best going with earphones with better waterproofing like the QY7 and QY12 earphones.
As far as overall audio and sound quality, the QCY T2C TWS in-ear have a loud volume with clear sound, good bass and treble reproduction.
The supported audio codecs by the QCY T2C TWS in-ears are SBC and AAA which is high resolution audio for iOS devices. AptX isn't supported so there is no high resolution audio support for Android devices.
