I’m not familiar with these particular models, but in general good IEMs will always provide better isolation than any over-ear headphones, Including noise cancelling, sometimes by as much as 10 dB. The best noise-cancelling over-ears will typically provide noise reduction in the -20s dB, while IEMs, if fitted properly, can be in the -30s. Another consideration for noise cancelling: noise cancelling works best at reducing more continuous, steady-state noise like airplane engine noise. It doesn’t do as well with mid-upper frequency sporadic sounds like voices. If your goal is to be able to listen to music while your wife watches tv, unless she’s going to wear headphones too, you need IEMs.
