Summary: I keep coming back to these since they are about the best I have found for volume control and comfort. The small protrusion in the earbud takes a few minutes to get used to if you plan on laying down on them like I do.
Pros: "Very few ear-buds with 'volume control' actually control the ear-buds, most work only to adjust the 'player' (mp3, phone, etc) volume. This means your volume is in 6-8 stages rather than being truly adjustable. Also once you get to a certain level the sound cuts to zero. The JVC HA-F75V controller allows better flexibility. My use for these are for drifting off to sleep and I drop the volume MUCH lower than my 'player' controls would ever allow me. And yes, comfortab...
Cons: a 4 out of 5 for the wiring around the volume control. It needs beefed up. I have had 3 pair over the years and each failed at the same point. I'll be adding a drop of rubber cement or silicone to my next set to see how that works. Keeping in mind I sleep with these so this are might get some unplanned abuse in the middle of the night.
Pros: Provides the low response end as advertised unlike a majority of earbuds out there.
Cons: If the earbud is not properly in the ear, the sound suffers due to the requirements of the design and the transfer of sound. In otherwords you will hear the other one better if it is in your ear until you readjust.
Summary: The ear buds had no bass at all! The sound quality was not as expected, it was poor. The in-line volume control did not work, the half way and maximum sound levels were the same (actually this is the main reason I did not like the earbuds). I do not know whether that has got anything to do with price of the buds. Even at this price, I expected a better product from JVC.
Summary: Dispite what the box says, the bass here isn't too great. JVC's other earbuds, the Marshmallow line, easily puts out more bass. However, the length and volume control are useful, and they are comfortable and go in much more quickly than the Marshmallows and Sound quality is decent enough, I guess, if you aren't worried about the bass, but I'm not an audiophile.
