[Upgraded]SYL Bluetooth Headphones With TF SD Card Slot and Clip, Sweatproof MP3 Wireless in Ear Headsets, Bluetooth 4.2 Noise Cancelling Sports Magnetic Earphones with Mic for Gym Running (Black)

Look they work (at least the functionality I care about, which is the TF card functionality). But they come with no manual, no instructions on the box, and apparently no instructions anywhere on the internet. It was sheer fluke of pressing the power button a few times that I put them into TF card mode, and I have no idea how to switch them to BT mode, how to pair them in BT mode, or how the TF card mode REALLY works (what determines the order in which files are played? is there a way to support folders?)This is utterly ridiculous. Look, if they want to save a penny and save paper, that's fine, but at least include a URL pointing to the manual!OK, so assuming the lack of manual doesn't bug how, how about the rest of it?Sound quality and volume are fine, better than you might expect at this price level. Not sure I like the horns on the ear buds; they may make the seating more secure, but they also mean that you have to put one particular bud in left ear, one in right ear. That matters because it then means the controller is in a particular place, against your neck on the right hand side. And that's NOT very easy to manipulate...That gets to my other primary complaint; the controls are much more painful to use than they need to be. They were very much created as "we need controls, what's the easiest cheapest place to put them", not "how can we design these controls for easy access". There's a reason that the high end versions of these sorts of devices put the controls on the ear buds themselves --- that's just an easier location to tap.Could these be designed better, but still as cheap? I think so, with a pendant design. Still the cord around the back of the neck, but an additional cord like a necklace in front, with the little stub of electronics, battery, and controller hanging in front of you on your chest -- much easier to access and control.There are other niceties that I think really should have been added --- they'd cost a little more, but could also justify a higher price. Most obviously, some sort of "in-ear" detector (maybe capacitive?) that would automatically pause when you pulled a bud out your ear would make them so much more convenient to use.So, yeah, for ~$15 they're not terrible. But I just wish they rather cost $25, and that extra cost went into making them so much more usable, and with a better customer experience.

Purchased 3 headphones for work. They started off excellent. music play only last 2-21/2 hours...not 4 as noted. After 3 weeks, charge lights didn't display on all 3; and one out of the 3 stopped working entirely.

I was really surprised at how good these work .. great price and good quality.

Sound quality about what you would expect for the money. Battery life is almost nonexistent. Save your money.

all good

So...heres what happened. Ive owned a boat ton of wired and wireless headphones. However, I am a minimalistic at heart. I dont like carry around more than I need too. So I decided a while back to get bluetooth headphones with MP3 built in. Theres not many options out there surprisingly. Since I use the hell out of wireless headphones for the gym, I decided id be willing to spend a little extra on the investment. So I ended up getting the Alpatronix HX250 for $75 (Yikes!). Although not absolute perfect, they really were great headphones. Problem was after a year, the left ear bud stopped working. Even though I never beat them up. Seems it happened to a lot of others too. So I decided to plunge and buy another pair and hope for the best. 3 months after that, I ended up losing them (the wire isnt stiff so they dont stay well around your neck, where I usually place them when Im not listening. They must have fallen off and I didnt notice).So to review....just lost out on $150ish on headphones. Wasnt planning to lose more. So my search for my now spoiled obsession with wireless headphones with mp3 capabilities brought me to these headphones. I honestly did not expect much because they were only $10. But I have to say, I was surprised.These are not as good as the Alpatronix HX250, but they are $60 less. So its really no comparison. The sound quality is surprisingly awesome and pretty loud.Pros:1) Great sound2) Low cost (cheaper than some wired earbuds that sound worse)3) Bluetooth and Mp3 enabled4) magnet for keep around your neck5) they are comfortable. Can wear for a couple hours without even noticing they are there6) they stay in my ears because of the ear hook. I did 100 jumping jacks and although they may have slipped out of position in my ear, they didnt fall out.7) Bluetooth only works if the SD card is removed. oddly I am listing this as a pro because I hate when im lifting and people call me and the music stops playing. lol8) micro usb cable charging. The Alpatronix were water proof and had a proprietary charger. I HATE PROPRIETARY CHARGERS!9) Bluetooth mode sounds jsut as good as mp3 mode (I havent tried for calls yet)10) small footprint11) powering on continues the music where you left off.CONS:1) The magnet is a nice feature but it is way too weak. I had to add my own neo magnet into the mix which made the connection super strong.2) m not a fan of loose wire, wireless headphones. I want wireless because I hate wires. These flop around as they would with any of these style headphones. I ended up using zip ties to make them shorter which worked out great, but doing this negates the magnet feature as they no longer reach around your neck.3) battery life sucked after a week. The first week was amazing. Lasted 4-5 workouts. 2nd week lasted 3-4. Now its only lasting 2 workouts. There is no warning when the battery is low. It just shuts off and done. (in all fairness I only use MP3 mode with the volume fairly high. So might be better results with bluetooth and lower volumes)4) only plays mp3s (and wavs according to another user. I havent tried because who uses WAV files...really?). It does not play any of my m4a files.5) NO SHUFFLE! lame. My work around for this is ever so often I use software on my computer which randomly generates random file names. But I have so many music files on the TF card that I do not have to do it often at all.Thats about all I can think of. I will still continue my search for something better mostly because of the battery life is killing me. Ive already had 3 instances where I had to workout without music which is DEATH to me. Sony has a few MP3 headphones but my experience with any sony mp3 products is proprietary chargers and they force you to use their software to get music on their products. JBL makes a pair called 'Dive' I believe, but it only has 1GB internal. Not enough for me. Alpatronix were nice but proprietary charger and failed after a year without any abuse. And all those above are larger in size and expensive!These are $10 and are pretty decent for now. Id say they are even worth $15-20. They are great back up headphones if anything.
