Inline mic echo sound on teamspeak?

[oo2k15]

Okay so I recently got Turtle beach mp3 headset with inline mic http://www.amazon.ca/gp/product/B00726ARLW/ref=s9_simh_gw_p107_d0_i1?pf_rd_m=A3DWYIK6Y9EEQB&pf_rd_s=desktop-1&pf_rd_r=0Z5B3QW91HHTMXWCJ5CS&pf_rd_t=36701&pf_rd_p=2055621862&pf_rd_i=desktop. When someone talk they can hear themselves talking through my mic and I can hear myself talking as well, I can hear their echo/feedback and plus they can hear all the background sound I have on my computer. Is there a way to fix this issue? Right now I have it push to talk, but I don't like doing that.
