designmaddie 1.0SENNHEISER IE 40 PRO is what I have been using for the past year. I enjoy the clarity of the sound. It really allows me to hear my flaws perfectly!
ilarisivilsound 1.0I wear IEMs on hot days or in the cold to be able to wear a beanie. The ones I use (Sennheiser IE-40 Pro) sound pretty similar to the HD-25s I normally use for the top end, but sometimes I don’t get a proper seal and I miss out on really low frequency handling noise. Also, set awareness is harder with IEMs. I wouldn’t mix with IEMs but I’m sometimes quite happy to boom with them. Normally I’m pretty happy with using HD-25s with velvet pads. So much more comfy than the pleather.
popokatopetl 1.0I've tried 3 pairs of IEMs in the 100-200 buck range (Senn IE40, 1More, Samsung) and none of them was anywhere near the over-ear open-back Senn HD560S.
