Question: does it stereo combined or do you only get one channel?
Document: Until I screwed up and bought this garbage one earpiece "thing", I never knew they existed. Yea, it's my fault for not reading the details but I assumed all earbuds were 2 piece stereo. A single earbud is a stupid idea as far as I'm concerned. I'll be more careful next time I order. There are some really idiotic products out there and this is one of them. Won't be buying from Jlabs again.
I usually wear one earphone during work so I can still hear what's going on around me. The problem with stereo is that you loose a lot of the  music when only one earphone is in place. This eliminates that problem completely. The sound quality is good, but my stereo pair is a Klipsch, which sounds phenomenal. The cord is thick and sturdy, overall good quality. I have yet to utilize the microphone.
This is a fantastic product! I am deaf in one ear and have been trying all kinds of single ear buds to listen to audio books and music while waling and bicycling (yes, I am one of those people). Most of the experiments have failed with a couple of mediocre exceptions. However, the J4MS rocks! I have to turn down the volume, and quite a bit at that, on my Android phone it is so stereo sound efficient. Also, the J4MS comes with a wide assortment of ear bud fittings.
Great one ear headphones. Nice to have the microphone on there in case you get a call while listening to music. I would purchase them again.
i have always had regular ear phones and always have to have one out of my ear while driving or whatever i was doing, just to hear what was happening around me. i saw this and tried it, and i must tell guys its been perfect for me. works really well. get this if you are someone who like to talk, listen to music and still hear and know what is around you. RECOMMENDED ! !
Bought these as I needed a headset I could throw into my laptop bag and use while at work for teleconferences. They do a great job with sound quality, they are built solidly and do not get tangled even when they end up buried in my bag. The only reason I did not give the 5 stars is because they do not come with a clip so the microphone stays in one place, otherwise I highly recommend them.
!.#3 I listen to my music while I play tournament poker - again I can still hear what's going on around me. Music sounds great. I would not have expected it out of a single ear bud, but it does sound like stereo.Really enjoying my music with these and appreciate the safety factor.
I'm a cyclist.I wanted a single bud headphone so I don't miss road sounds, etc and these definitely fit the bill.GOOD POINTSSingle ear budGood stereo soundEasy pause and skip functionLong cordHeavy duty cordNon tangle cordBAD POINTSDon't even want to put anything on here because I love the bud but....If you plan to use this ear bud with your phone, the microphone isn't heard well by the person on the other end of the line.LOVE THIS PRODUCT&#62;Highly Recommend
I love this in-ear single earphone. The sound quality is WAY better than any bluetooth devise. And because it is not a double earphone, the wires hardly get tangled.
I have to admit it, I'm really hard on ear buds; I have killed so many in the last few years I couldn't even begin to count. I started buyingSamsung Galaxy Tab Hands Free 3.5mm Stereo Headset - Black (EHS60ANNBEGST1)5 at a time, which sound good enough and are inexpensive but I was just burning through them.So I went looking for rugged ear buds and figured this was just the thing. Unfortunately it died just a little over 4 weeks from the original purchase, which is the end of the Amazon warranty period.
Answer: The stereo channels are combined. Hope this helps.
