    Easily my go-to for budget bluetooth earbuds

    This is actually my *third* pair of WI-C100s- the first pair lasted a good several months (if not over a year) but the cable from the battery to the earbud came loose on one side; the second I lost on the way to work after months of use, probably while having to run for a bus or snagged on my backpack strap and fell off (was...not a good morning hah)So....yes, since they're so light they are easy to slip off accidentally if you don't have one or both ears in-use to keep it from running off your neck (mostly when running or leaning/laying back, basic day-to-day activities don't usually knock em

    Great wireless neckband earphones with a couple shortcomings

    I've used its cousin, the WI-C130, for the past two years and felt like it was about time to replace them given their waning battery life. I've used those out and about, listening to music and, most importantly, while lying in bed listening to audiobooks (including side-sleeping). Most earphones aren't comfortable for that; either they poke out too much, are generally uncomfortable, or too loose/unsecure. But these (both C100 and C130) are amazingly comfortable for that use-case.The WI-C100 is comparable to WI-C130. Given Sony's notoriously confusing naming scheme, its not clear which of the m

    Best earbuds I've bought in a long time

    I bought these earbuds to replace the beats I've had for five years. Not only were they less expensive, but they fit my small ears better. Before finding these Sony earbuds, beats were the only decent earbuds I could find that worked with my stupidly small ears. Not only do these fit better, but they sound better, have more features and have awesome battery life!I didn't know they had an app to adjust the sound quality. The app has several pre-existing sound profiles and three profiles you can create yourself, which really helped with my weird hearing ranges.The fit is perfect using the smalle

    Fine with a few little issues

    Surprisingly good. Far from great but I have had fewer issues with these than most earbuds. Sound is ok, I wish you could change the sound EQ setting on the Sony app but no. Mine have a slight balance issue as well where one side it slightly quieter but that probably does not apply to most units for this product. Outside of that good battery, cheap. They don't have magnets or a semi rigid neckband which means they will slip off sometimes so not good for exercise. Fine for at home or maybe work listening though.

    Possible budget option but definitely cons

    I really wanted to like these more...in fact, initially I thought they were great, but the more I've used them, the more I've considered returning them.These replaced a few-years-old LG Tone headset/headphones so I compare these to those. That was my preferred style/pair (a plastic band worn across the back of the neck, with the earbuds coming out the ends but easily connected to the band ends by magnets. I first got LG Tone as a gift about 10 years ago, for my first Bluetooth headphones, and liked them so much I would just get the same (on eBay) every few years when one of the earbuds would l

    I don't know why I ever bought anything else

    I was a big fan of JLabs earbuds and headphones but recently had a bad experience with one of their products. I have been the market for bluetooth earbuds that had an inline mic. I have issues with some bluetooth earbuds not connecting and/or staying connected to my Windows 10 Microsoft Surface Pro. The JLabs Pros that I tried would connect fine but would disconnect after a few minutes. I also had issues with them on my Android phone.I bought these Sony WI-C100s to try. WOW...just wow. I don't know why I ever stopped buying nothing but Sony products. First, they connect to my Surface Pro perfe

    Faithful Headphones

    I've purchased this model headphone 4 to 5 times. Only one of those times were the headphones broken. The quality of sound and the 25 hour plus battery life is awesome. I also like a wire connecting the left and right ear as I am less likely to lose them as I am an earbud. $25-$30, you really can't go wrong.

    Good Sound But With Some Issues

    I was in need of a new headset and bought 2 different sets - this and the Tonemac N8s, both were in the under $30 range. There is a more detailed review for the Tonemacs on that product page but I will touch on a few points for both in case others are comparison shopping.The Good:1) The Sony headset has an exceptional sound at this price point. Solid bass, clear vocals and treble, no muddled sound. You can distinctively hear individual instruments and vocal tracks, sounds are crisp and clear. They sound higher end than the price point and significantly better than the Tonemacs.2) The Sony buds
