Summary: I had the FX101s for a short period of time and I was really enjoying them. That was until something went wrong in the left earbud. Most say its a cable connection fault. No matter what, build quality is a cause for concern in these, especially the cable.
Pros: Extremely good for the price, great for amateur bassheads, look better than average
Summary: The bass is very good for the price and the driver size. The sound however, could be improved further by equalization. The highs are suprisingly good but these headphones are lacking a bit of the mids. These headphones are very lightweight and comfortable, allowing up to long hours of use.
Pros: Good bass, very comfortable and lightweight.
Cons: Requires a good burn in, poor build quality.
Summary: Comfortable, well-built, and not at all microphonic, the JVC HA-FX101 is a bargain that should cause the bass-obsessed to salivate profusely. The bass-heavy sound means that these are far from the most neutral or natural-sounding earphones, but they deliver on the fun factor without sounding...
Pros: Well-built, comfortable, minimal cable noise, tons of bass
Summary: I found that I had to constantly adjust these to get a consistent sound, and doing so stopped me getting into the music. Because of this I sold them quickly. They sound similar to Etymotic ER6i, with perhaps better bass. I'm not sure if they distorted treble slightly.
Summary: When I received these earbuds I was not expecting much. I read reviews on the FX1X and FX3X, and both were laced with caveats. The few posts I found on the 101s said (more or less) that they were the least riddled with problems from the XX product line.
Pros: Fairly clean bass, break in time repairs some sound hiccups, low price.
Summary: I purchased these headphones because some other Head-Fi-ers recommended them to me. And the community is now 2 for 2 in recommendations for me! These are some pretty serious little earbuds. They pack quite a hefty punch, especially for the price, just 17 bucks!
Pros: Excellent bass, audio quality is surprisingly very good, best bang for your buck.
Cons: Very thin cable, cable catches movement noises, no EQ means some piercing highs.
Summary: Wow. What a value these are. Amazing clean punchy deep bass, great mids and sparkling highs(hot almost) all for $14. Without any eq the bass is just darn powerful. Not muddy, but deep, punchy and plenty of it. Turn on the bass booster and insanity happens.
