Running Headphones,Syllable Wireless Bluetooth Earbuds with Mic V 5.0 Hi-Fi Stereo Richer Heavy Bass Noise Cancelling Headsets Sweatproof Secure Fit in Ear 6 Hours Battery

I use headphones about 12 hours a day, and end up going through a lot of them. While I converted to bluetooth headphones several years ago, this is my first set where the left and right earpiece are completely separate.The complete elimination of the cable tether between earphones has many benefits. No more bouncing cable when running, no more snagging of the cable (which has led to the majority of my headphone failures). And it allows for one to only wear one earpiece and keep the other ear free to listen to the surrounding environment - perfect for the office setting or when commuting.Build quality looks solid. Having broken probably about 5 sets of bluetooth headphones, most have broken from the cord getting caught or the housing breaking at the location of small screws. I've already mentioned that their is no tether to snag. There are also no screws holding the casing together. I expect this set to hold up better than most competitors in a similar price range.The listed 6 hour battery life (which seems about right from my testing, is usually a little less than what I would like. However, since you can operate a single earpiece at a time, you can effectively double the battery life if you listen with one earpiece at a time. And the batteries also charge very fast.As far as fit, these are great. The rubber piece that rests on the ear actually has a malleable metal core, so that the earpieces can be modeled to adjust to individual ears. Crimp them on tight for running, and loosen them more comfort.Another positive is the sound level and sound quality. Many bluetooth headphones are relatively quiet and require you to max out the volume control on the headphones and almost max out the volume on your phone if in a noisy environment. These earphones do not have a separate volume control, volume is done solely on your phone. However, they are very loud, and I bet I could even wear these on an airplane and hear music over the background noise.And while I can't say for sure that the sound quality is fantastic (I listen to books and podcasts, not music), these headphones have an impressive amount of bass.The documentation was a little sparse, but bluetooth setup was far easier than I expected. Initial pairing was no trouble. After that, turn both left and right earphones on at the same time to pair both. Turn only one on, or turn them on at different times, and sound will come out of only one.The only issue I've run into is that about 3 times a day a single earphone will toggle between pairing and unpairing. Lasts for about a minute then stops. Not sure if its an issue with my phone or the headphones.In the end, a great value, especially for a price.

Update 02-10-19- But problem began a while ago, shortly after I bought theseWhen I use this to run or work out while connected to my Apple Watch S4 the rights earbud does not stay connected- not even for 5 minutes. We're talking 2 feet away here. Extremely annoying and makes them useless for working out. I have tried re-pairing multiple different ways with no success.So, I've read the other reviews and the biggest complaint was connectivity- this happened to me on my iPhone 6S Plus. If you follow this seller's instructions you will end up with TWO- D15 devices to connect to. If you connect to BOTH you will have sound in only ONE ear at a time- Weird, right, but true story. I searched and found the instructions from Syllable Direct on Amazon- See Below-1. Power on: Press the buttons of the two earbuds for about 1 seconds till the lights flash blue, Waiting for about 3 seconds, the light of left earbud will automatically change into flashing blue and red alternatively, the light of the right one keeps flashing blue2. Search & connect: Turn on the Bluetooth of your phone, search D15 and connect the earbuds, when connecting successfully, the lights of the two earbuds will flash blue every few seconds see lessBy Syllable Direct SELLER on August 29, 2018You have to connect to only ONE D15 to get sound in both ears, if you have two, delete the second connection. Once through that chore these are off the hook! Amazing Bass- easily as powerful as my Mpow wireless (with neckband) and great clarity across the range. No connection issues with phone in pocket. Left phone on desk and walked across apartment- two walls and over 35 feet- No issue at all.They have a solid feel, fit very comfortably for me (the hook and earbud have a soft silicone feel) with zero discomfort on a 5-mile run.I have a pair of RHA 750i wired headphones, as well as Bose QC25, and Sony MDR-7506. Keep perspective, if you do these are relatively as good as anyone listed above. For $17-$19, they are an absurdly good deal and worthy of a second pair.Warranty Hack- The Headphones are selling for $16.99 with coupon at present. I bought the 2-year Asurion plan for $1.95 because I've always had great service with Asurion (never Square Trade). For $19+/- I have a pair of wireless buds with zero risk. If they stop working its as easy as an email to replace or get the money back to move onto something else.

these headphones have phenomenal sound. They are inexpensive, light weight and have supwerb bass. They are in my opinion better quality than the Aminy wireless ones I have. I've gone through many headphones and usually the same thing happens. The one ear stops working or the wires mess up. i used to buy those expensive LG wrap around your neck ones and it's not worth it. The aminy are my first true wireless earphones I've owned and used. The sound is loud, but not stereo or club quality. You cannot truly tune out those around you. I loved them, but the control/power button for the right ear fell off and without it you can't use the headphones for music or calls.Now these headphones right here, the syllables are amazing. I do not have to turn them all the way up to tune out others around me when I go outside. I do this because i have serious anxiety. These do not fall out when you walk, run or bend over to tie your shoe. I did have a problem with them though. They would not charge and the return window was gone. I think soemthing was wrong with the usb cable provided or the main earphone cause they wouldn't stay on even after two days of charging. The seller graciously sent me a new pair very quickly i might add. I am very grateful for this and would buy from this seller again. So don't spend all your money on expensive headphones when you can just buy these.

Third Syllable I have bought and I highly recommend them. Will buy again

Received Defective earphones and a defective cable.
