Benefiting from five years of evolution in design, sound quality, durability, and comfort, the J4MS single earbud-style Mobile Headset is ideal for those who need a single (1) earbud with microphone and answer call/button control for smartphones, tablets, and other mobile devices, including Android, iPhone, iPad, iPod, Motorola, Palm, HTC, Windows, Kindle Fire, and BlackBerry. The J5MS's titanium micro driver delivers an incredibly smooth and consistent sound quality. The all new 45 degree angle jack leverages the strength of pure metal with the durability of flexing rubber. The lightweight cable is reinforced with Kevlar for optimum flexibility and strength. Sleek housing ergonomics deliver an ultra comfortable fit with a satin soft feeling inside the ear. The J5MS is so comfortable, you can barely feel you're wearing a headset. Includes 4 silicone cushions as well as a clip for securing the cable. Please Note: This product has one (1) earbud and is designed for cellphones, 2-way radios, etc. If you are searching for stereo earbuds (2 earbuds) for your music player, try the JBuds J5 or the J5M with mic. Backed by JLab's limited one year warranty and world-class support.

Customer Reviews

Great earphone, comfortable and has good sound quality.
lchin
The mic gets funky due to the direction it faces sometimes--which can be fixed with a clip--but why bother, I'd just cut the mic and just talk into the phone receiver.
Cosmo
I have owned this earphone for two and a half weeks and they do not work anymore.

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.

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 buying Samsung 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. I contacted JLab's support and spoke to Brandon, who was very helpful. He explained that I have a year warranty and gave me the details on how to fill out a claim. It took a little while, but I received the replacement.

The first one hasn't proven any more rugged than other ear buds, but I'll report back on the second.
