I have not tried this, yet, as I do not have a mod-mic at this time. So yes they offer DEEP HEAVY BASS. I think they came up too high on her ankle Definitely would recommend to anyone whose earbuds always fall out or dont like being totally cut off from any other noise. Otherwise these slides are PERFECT. It was extremely tiny like it?s for a 2 months old baby. They were exactly as ordered and delivery was as expected. They usually last me 5-8 years so even though they may seem a bit pricey, they are so worth the money. Literally have had them a few hours. I dont mean they dont have booming base, I mean its like any bass is completely turned off.
