The h.ear in Wireless Bluetooth In-Ear Headphones from Sony allow you to stream music at a bit-rate higher rate than CD's 16-bit resolution, providing audio that parses digital signal into more and better defined segments. Therefore, music will sound more faithful to how it was produced in the analog realm; no more carping about lossy MP3s—now the entire audio world is your oyster. These earbuds accomplish this feat wirelessly, via Bluetooth, with One-Touch NFC pairing, and utilizing Sony's proprietary LDAC codec (so long as your device features LDAC at the SRC point). Thanks to the in-line remote and mic, the h.ear in can also be used to take hands-free calls, and switch tracks without ever having to touch your smartphone.
These earphones feature a 0.35" dynamic driver unit which reproduces frequencies between 5 Hz and 40 kHz—beyond the range of human hearing in either direction. Also, Beat Response Control technology delivers a tight bass response making it suitable for low-end focused music styles. Four sets of ear tips come included with these earbuds, as well as a carrying case. After charging them, they'll last you up to 7.5 hours.
