Pryma Headphone by Sonus Faber 'Carbon Marsala' edition review. Youtube review: Photo: http://dalethorn.com/Photos/iPhone6p/Headphone_Sonus_Faber_Pryma_01.jpg Sources: iPhone6+ with Oppo HA-2/Beyer A200p DAC/amps, various computers using the HRT Microstreamer/Audioquest Dragonfly/FiiO E17k/FiiO E07k DAC/amps. Review note: My evaluation of the Pryma's sound is based on comparisons to a number of premium headphones, so that my estimation of its overall balance, tonal quality, and smoothness (lack of peaks and recesses) is referenced against those other headphones. The sound of the Sonus Faber Pryma is smooth enough that the term 'liquid' may best describe it, particularly the midrange. The headphone I have that's nearest to the Pryma in the midrange and treble is probably the Audioquest Nighthawk, however the Nighthawk can be like a chameleon with different amps and music players, while the Pryma seems less affected by different gear and sources. Whereas the Nighthawk's bass has a broad and significant emphasis in the lower mids to upper bass, the Pryma's emphasis (if any) is lower down, resulting in better impact in the bass. There are few headphones that I've had with very similar bass, and the closest examples I can think of are the MrSpeakers Mad Dog, B&W P7, v-moda M100**, and possibly the Sennheiser Momentum. The more expensive planars that I've reviewed did not have a particularly strong or warm bass - by my standards anyway. **The M100 bass is much stronger, but its excellent character is similar. I have to pause here to note that I didn't expect a great audiophile sound with the Pryma, being that it was promoted primarily as a high-fashion headphone. So far at least, given ample burn-in and listening time (see the music examples below), the Pryma is living up to its designer's claims for premium sound. Personally, I place it sonically with my five best (out of about 200) headphones ever. A few months ago I described the Nighthawk as having an unusually smooth sound, but finding the Pryma to be just as smooth was surprising. Soundstage isn't easy to evaluate since it's dependent on so many other properties, so I'll just say that the Pryma's soundstage is very good. The Pryma plays loudly and cleanly with my music tracks on the iPhone6 Plus, but some users may have a few low-volume tracks that won't play loudly enough with cellphones and similar handheld devices. A good DAC-plus-headphone-amp will provide better sound than cellphones and ipod-type players alone. What makes the Pryma unique for me is it's the first triple-A-plus headphone that I've had, i.e. the packaging, the design and build quality, and the sound are all as good as it gets. If that wasn't enough, it provides premium sound for listening at home, and is an ideal portable headphone. To me, the ideal portable is a headphone that I can pull off of my head when I stop for coffee or to talk with someone, and drop it around my neck where it doesn't get in my way at all. Isolation is modest, but useful, and while it might not be enough on the tube or the bus (let alone a jet plane), I use it in a public park about 100 yards from a busy freeway with no issues. The leakage is low, but will probably be heard by people sitting close by in a very quiet public library, so the volume would have to be kept down in those kinds of places. The headband adjustment is 11.5 mm on each side for heads larger than average size, and 23 mm on each side for smaller heads. That adjustment range should fit the vast majority of headphone users. The earcups completely enclose my average-size ears, but people with very large ears might regard the Pryma as "on-ear" if they can't get their ears into the openings. The earpads are soft and spongy, and the openings are deep enough that my ear-parts aren't pressed against the drivers inside of the earcups. The earpads are attached magnetically and pull off easily, so replacing those is very simple, although given the earpad coverings I don't see replacing them for years to come. The headband is detachable as well, leather-covered, with some soft spongy material underneath. In spite of the metal in the headband and around the earcups, the comfort is among the best headphones I've had, due to the thoughtful design. My version is the "Carbon Marsala", with the carbon-fiber outer earcups. The Pryma comes with a detachable double-entry cable, connecting to each earcup with 2.5 mm mono plugs, with a 3.5 mm stereo plug on the business end. That plug has the extra connector for smartphones, providing start/stop and next/previous track using the clicker next to the microphone, which are about seven inches down from the right earcup on the cable. The comments in the music tracks listed below can be compared to other headphone reviews I've done, to get an idea of how the Pryma plays the different music tracks listed here compared to other headphones. My suggestion is instead of reading each comment below as an absolute unto itself, you could compare these notes to other reviews as they get posted, and see how the Pryma compares with each individual track.
