In case anybody missed reading it, Grover Neville (over at inner/FIDELITY) had these words to say about how the HF-3's sounded:
"Next up was a company I had not expected to see at this CanJam, or really any CanJam ever. Grado Labs had a separate room outside the main event space, showing their third Head-Fi collaboration headphone, the HF-3, as well as a variety of the rest of their lineup and a few special editions. [...] I came away with a lot more respect for Grado’s design abilities, both after this conversation and after listening to the HF-3 Head-Fi collaboration. It looks much like a simpler RS headphone, and sounds nothing like any other Grado that I’ve heard. Theres smooth, balanced, bass, a relaxed midrange and open and very smooth treble. All of it does a great job of sounding both natural and clear, with a surprisingly good stage depth. No, bass didn’t extend to the most titanic low notes, it still had those awful foam pads and the overall sound profile isn’t going to give you HD800 levels of sound staging, but this thing certainly sounds like a headphone designed by folks who know what a competent modern headphone should sound like. While I feel I have a better understanding of what Grado’s target audience is, the HF-3 left me wishing they would do collaborations and on-off products like this more often."
