If you're an audiophile, then you'll hate these ( and seriously, why would you be looking at <$20 speakers? Stop wasting your time and ours!). For anyone else, the sound quality is not bad at low indoor volumes. At higher volume levels you'll notice the lack of bass, but the sound is still not bad. I got these to try out the whole idea of a neckband speaker, and for the price, they're fine. If I find myself using them a lot, I'll maybe invest in a higher quality product and keep these as a spare of disposable beaters. I can wear these a lot longer than ear buds and earphones. Others can hear my music, but it sounds very low to them.Pros:Low priceSound is not terribleBattery life seems goodCan play MP3 from an SD cardCons:Made of hard cheap plastic. If you're using a chair with a headrest or small pillow, then can dick into your neck. A larger head pillow takes care of that.No way to adjust tightness, so they can fall off if you're moving around- I find that putting them under a T-Short collar works well for this.The pause button is not the frontmost button. The frontmost button changes to FM mode, which is mostly useless. I can't pick up any stations.Good battery life. I have not tested it a lot, but I can estimate these going at least 8-10 hours while playing music
