Summary: Value: For an asking price of $55-60, it is a very good deal. The sound quality is above average for this price point. Best buy among the SJ series and will give you a taste of entry-level "HiFi" sound.
Audio Quality: Against its little brothers the SJ11 and SJ33, the SJ55 headphones stands-out by a mile. It has this mild touch of HiFi sound into it. With that, I'll be comparing this can to the WS55.
Pros: Affordable, heavy-duty build, great sound quality for price, swivel features
Summary: This piece of headset is over the ear design so sound isolation is not the best and my ears hurt after long period of constant listening, but this is an over the ear design drawback not product fault. When worn with my Sony Walkman on about 70% of volume I cant hear even an incoming truck. They do look and feel plasticky, but I find it sturdy built and have no issues at all.
Great replacement for my Creative Aurvana Live headphones
1 May 2013
Summary: I bought this to replace my creative aurvana live headphones, which i thought were not really going to be beatable for value, but these headphones are in fact better. I use them with a fiio e6 amp, and they're preferable to my phonak PFEs & to the aurvana live headphones. Excellent bass, clarity, noise cancellation, separation. I also use them for DJing and they work very well, and they fold easily making them very portable. Highly recommended.
Summary: I bought these a few months ago for a change from some smaller headphones. I checked the specs a out and not having the hearing of a dog the frequency range was great and better than those DR Dre efforts (in my research). I listen to all sorts of music and have no faults with the sound quality. They are well made and can fold up and the cups turn in making them flatter. This is handy when traveling as they pop into the laptop case when not in use.
Summary: Although I have little to compare to besides earphones I have found these to be very disappointing. The sound quality seems fairly good, I much prefer them to earphones, but this is partly personal preference. Although they do not feel particularly well made or sturdy, with a folding design which I would have rather they didn't include, they have lasted without fault for a year. My main problem with them is their sound isolation.
