I purchased 2 of these to replace a Shure headset that I loved but had left in a pocket and got put through the washer. After researching for a bit, I decided to go with the J4ms since the J3ms was getting quality complaints.

Neither of my headsets is capable of transmitting sound. I can get the phone audio but the person on the other end cannot hear me. It is the same with both headsets.

I have an AT&T branded Bold 9900 just to be specific.

Update:

This was a total bonehead problem created by me. I had updated the OS on my phone to the beta 7.1 software that enables hotspotting. I downgraded my OS and the headset worked. I am amending my review from 1 star to 5 stars based on the fact that I have a working product now. The problem is more a reflection on RIM (as if they needed any more negative reviews) then on JLabs.

I also want to compliment the JLab technical support person that I spoke with in trying to resolve the issue. He offered ways to resolve the issue and was very helpful. After some use, this headset is comfortable and exactly what I was looking for.

Noise Isolation: The inserts provide a bit better sound isolation than my cheap $10 Sony earbuds from target. Not as good as sound isolating buds of course, but it's a noticeable improvement. Ships with around 8 extra inserts of different sizes and types.

Playback Quality: It's ok for an in-ear, cheap earphone. The bass is a bit punchy though which is nice. Voice quality is good even if music playback is somewhat lacking. Music quality seems a bit better after using it for a week (burn in). Note that JLab's has some special burn-in instructions on their website.

Android Compatibility: This is the reason I bought this headset. The button on the microphone housing will pause audio playback on my Nexus S 4g. Works for both the default music app and my podcast app "BeyondPod".

Other notes: Cable is fairly long (4'3" or so). Treble boosting equalizer settings make the audio output more to my tastes. Also, see the bulky nub right near the headphone jack in the pictures? I was worried I wouldn't be able to plug it into my smartphone since I have a case on it which recesses the headphone port. Luckily there's enough clearance on the plug for me to get it in.

Microphone Quality: Jostling the dongle while talking to people (say if you're running or repositioning it) only produces a mild disturbance. Transmit volume seems a bit on the low side so you might have to speak up a bit. Haven't had a chance to test in windy conditions.

Update:

I recommend looping this earbud around your ear. It helps reduce noise caused by the cable rubbing against your shirt,it makes the earbud less likely to be pulled out of your ear, and it moves the microphone dongle up to shirt-collar level which gives better audio quality.

ATTENTION: this item is a SINGLE earphone headset.
if you're looking for a product with two earphones to listen to music, this may not be the product you're looking for.

however, i've used this product with my iphone4.
and this ear-piece is EXCELLENT.

i have a set of JLAB J3m's, and my complaint with that product was the way how it picks up noise from the wind.
this product does a GREAT job eliminating that unnecessary noise (almost not noticeable).

i give it a 4/5, just because since i don't drive around TOO much, and whenever i have something plugged into my ears, i'm listening to music, from both ears.
so i'd probably consider giving the J4m's or even the more recent products from JLAB, a try.

if you're looking for a single-ear product, this is an excellent choice!

I use thses at work to listen to music. They have a great sound for a single ear earphone. I plug in and put my iphone in my back pocket. This single ear JBud are truly rugged. I have used it for almost a tear now and they are great. Better than the IBuds I had before.

I purchased this because I kept losing the earbud cover off the other ear when driving. Having just a single ear piece to use with my phone is fantastic. I have asked and found that the sound quality is good whether I am holding the microphone up or whether it is draped with the clip while driving. Using with a Droid Incredible.

Pros:

- Very nice sound quality for voice communication
- Microphone does a good job at diminishing background noise
- Nice selection of silicone ear pieces, good job at blocking outside noise.
- Wires are not flimsy

Cons:

- Bass is good, but overall fidelity isn't that great for HiFi music.
- Build quality is marginal. My bud pulled apart on day one when i tried to change the silicone fitting. I glued in back myself with Duco Cement. No big deal, but disappointing.
- The wire is a bit stiff. I wish it was more rubbery and less prone to tangle.
- I wish the plastic around the 3.5 mm jack was a bit smaller so that i didn't have such a big clunky jack sticking out the side of my ipad or blackberry,
