Most so-called "language lab" headphones are sturdy, heavy  and have ear cups , which all helps with sound insulation. 

More helpful still may be the "sidetone" feature of the digital audio lab software that feeds your own voice, from a directional microphone back, into your headphone speakers.

No doubt our interpreting teacher would still prefer interpreter booths.  However, while I don't have any hard data on the acoustic attributes, we are just ordering a 2nd batch of Sanako SLH-07. 

Other digital audio lab vendors offer similar headphones (I know SANS does: http://thomasplagwitz.com/2013/10/28/a-few-thoughts-on-headphones-for-the-language-lab/). 

The price seems worth the time one can save troubleshooting lesser options.

Good luck,
