The Good Four SMS Audio Sync-equipped users can connect to the included wireless dongle for group listening, Kleer Wireless streams sound much better than Bluetooth, and SMS includes a 3.5mm cable to use when the battery runs out.

The Bad The delicate plastic housing and the flimsy 3.5mm dongle both suffer heavy creaks under light pressure, and the headphones don't fold up for easier transport. I'm also disappointed that the headphones don't actively cancel noise and that the single USB charger means charging the dongle and headphones separately.

The Bottom Line The Sync by 50 wireless headphones made the right move using Kleer technology for lossless sound, but SMS Audio needs to fix severe design flaws and lower the price before they're ready for battle.

If the $399 SMS Sync headphones are any indication of 50 Cent's contribution to the audio industry, he should continue churning out rap albums, energy drinks, and Vitamin Water, but leave the gear to the professionals. These are the first Kleer wireless headphones with corporate support from a hip-hop artist, but that endorsement doesn't save these headphones from some significant design flaws and an inflated price tag. Both issues need attention if these headphones intend to compete successfully against the Monster Beats by Dr. Dre Studio and the Soul by Ludacris SL300s headphones.

Design
The Sync by 50s are built for listeners who take fashion seriously and shop for headphones that match their lifestyle, but the thin plastic covering the set doesn't inspire confidence for anyone using them on the go. If you have a chance to check them out in person, be sure to subject them to a simple creak test and you'll find that the thin plastic connecting the headband to the adjustable joints barely supports the weight of the heavy earcups, causing the set to sway side to side with discomforting flex when they're not firmly planted on your head.

I wouldn't feel comfortable using them to exercise despite what the marketing says, and I suspect the six tiny screws exposed at the bottom of the headband won't likely survive a single drop onto hard concrete or linoleum.

The wireless dongle that plugs into the audio source is an equally disappointing misfire in hardware design. Small details make a big difference in headphones, and the offset 3.5mm plug feels just as awkward and weak as those abhorrent FM transmitter attachments that came out for the first Apple iPhone--a small piece at the end of the jack also prevents the whole adapter from sitting flush on a music player, causing an alarming degree of wiggle room between the plug and its housing. I would expect this construction quality from a simple $20 accessory, but definitely not as part of a $400 package.

You can buy the Syncs in either white or black, though I'm afraid of how the white leather earcups and padding under the headband will degrade after months of constantly pulling them on and off your head, especially if you live an area where the summer months may drip sweat onto the material.

The white-and-chrome model I received for this review is trimmed with subtle gray and blue lines detailing the headband seams and stretched throughout the earcups. Of course, SMS Audio labels adorn the top of the headband with more branding printed just above the left earcup.

Unlike the Beats and the Souls, the headband joints on the Syncs lack the ability to fold into themselves, so you can either sport them around your neck or store them in the included semi-hard, neoprene-wrapped case.

Similar to the Soul by Ludacris SL300s, a royal blue S (for SMS) blinks steadily on the left cup when you pair the headphones with the receiver in wireless mode. If you're not feeling the flashing lights, you can also toggle Airplane Mode by pressing the track navigation buttons for three seconds to turn them off and on again.

The wireless technology used to pair the dongle to the headphones is engineered and licensed to SMS Audio by Kleer Digital. It's different from Bluetooth headphones that compress the audio signal during transmission, which means that these headphones will carry a much cleaner, more robust sound than you'd ever hear out of competing Bluetooth sets.
