A stereo microphone just shy of being studio-quality. Very high quality and very highly recommended.
With no drivers needed, this thing has been tested and works on various Linux distributions, Windows XP, Windows 8.1 and Windows 10. I've also tested it as an audio output device (a "sound card") and it works great.
Not in stock at dx.com, but perhaps try one of:
A very high quality and easy-to-use dictaphone / mp3 player / usb stick.
A basic dictaphone and mp3 player.
It records with horrible static with both its in-built and provided microphone, but its mp3 playback is spectacular. Its utterly shit mp3 interface, slow song switching and no shuffle make it basically useless as a player.
I bought this lower-sized version because it mentioned having a lithium battery. It does not, which pisses me off to no end.
While this works, it is definitely not recommended. Buy something else, even if it costs more.
These are in-ear headphones. While spectacular, they are no longer available.
