Lots.
I have a lot, both free and for pay, at my site http://www.gentlybitten.com
Slutinmyhead mentioned above of course.
Quality varies wildly but there's a lot at http://www.warpmymind.com
Blink is awesome but kind of on hiatus now: https://castleblinkenstein.wordpress.com
SMOTP has some: http://www.smotp.com
WillDissolver is more oriented towards women, but open to both, and enjoyably evil: http://theexcessivemachine.info/wp/
Frost Endwood seems to be entirely furry-related: http://frosthypno.blogspot.de
And if that floats your boat, FurMorphed is *the* social-network site for gay furry hypno stuff (you'll have to be a member for a week or so to get to see the hypno stuff): http://furmorphed.com
And in the same vein, The Hypotic Beast (which might be entirely non-erotic, but furry): http://hypnobeast.com
I think HypnoDelica is straight, but his stuff doesn't mention gender and mmm, his voice: http://hypnodelica.webs.com
This list wouldn't be complete without mentioning HypnoSubmission.com, though it's video and not just voice: http://www.hypnosubmission.com
HypnoSuperior is trying out several different identities to focus on different markets (jock fetish, findom, etc); this one is his D/s ID, I think: http://hypnosuperior.com
I think Hypnotic4Play has some M4M stuff: http://hypnotic4play.com
Hypnotising.org is probably *the* M4M hypno social networking site: http://www.hypnotising.org/
Though iHypnotism tries to keep up: http://ihypnosis.socialgo.com
MajorPixel aka TheVoice666 does some completely filthy stuff, both on NiteFlirt and on WarpMyMind: https://www.niteflirt.com/thevoice666
ManInControl is mostly focused on women listeners, though he has a separate FinDom account where he's happy to have any gender: https://www.youtube.com/user/Man1nControl
MastrRelaxr is a bit website-design-challenged but has audios available (I think not actually for free, despite the site name): http://www.freehypno.com
Jadyn, who also posts to WMM, has a bunch of fun free recordings, either gender-neutral or with male-specific versions: http://www.mindcollar.com
Nimja seems to lean towards women but has a lot of gender-neutral stuff: http://hypno.nimja.com
Senator of Mind Control, conversely, seems to lean towards men but has some female-oriented stuff also: http://www.senatormindcontrol.com
I don't care for the word "faggot" but if you don't mind it, there's Shadow Priest: http://www.masteroffaggots.com
Skintightlover has an obvious bent towards latex and dehumanization: http://www.skintightlover.com
ViVe puts out a *lot* of free files, and seems to do particularly well with "dumbing down" stuff. http://www.vivehypnosis.de
And I'm still not sure what to think of serial-recruitment social-networking site You Must Obey, but it's definitely worth a look: http://youmustobey.com
