Etymotic Research HF5 Portable (Cobalt)

Pros: Nice build, great isolation, fair sound-stage, flat response across all frequencies

Cons: None for this listener

Summary: If you like warm sound with thumping bass these should not be on your list. If you've never worn in ear headphones be advised these guys fit deep into the ear and will be mighty unpleasant initially. I found the selection of sleeves acceptable and comfortable but I've grown accustomed to the experience over time. I actually substituted some foam sleeves from Shure and they seal well and are all day comfortable. Comply tips are also suggested if you don't like what comes with the set. The kit includes a dandy zippered case, extra plugs to prevent fouling from ear wax and a tool to change them if necessary. These are light, snug and will not fall out on their own. They naturally isolate external noise wonderfully so you can listen at subdued volumes and not miss a thing. I happen to have a digital player with a great equalizer and can add plenty of bass, also I have an amp with bass boost. Without this the bass is present, tight, accurate but not for everyone especially "bass heads". I happen to enjoy the bass from these. The mids are crystal clear, with plenty of micro detail but some may find it flat and unexciting. Again, I like it. The highs are well extended and treble lovers will like it, it lacks what some refer to as sparkle but there is no hint of sibilence and if you're not into it then you might find it fatiguing after a while. When all parts are added you get a fine listening experience, these will reveal any weakness in a mix and really low bit rate files will sound lacking. On balance if you want to hear everything in detail with great discrimination you can't do better for the price. The 2 year warranty is a plus. I hear the mike on the HF2 is really excellent if you use one.
