There is a lot to love about the SMS Audio SMS SYNC by 50 Wireless Headphones. You can see a few of the features in the video portion of the review, but here is the executive summary to the review. Please note - that I tried and owned dozens of headphones and earbuds - including the Beats Studio by Dr. Dre (which I returned). So hopefully I can bring some perspective to the comparison.

Sound Quality - Very impressive sound certainly comparable to the Beats Studio by Dr. Dre. - They may not have quite the booming bass as the Beats Studio, but they have smoother response across the entire audible range. I noticed a difference classical music they had a very nice response and were not overly bright. I am not disappointed.

Noise Isolation - These headphones do not offer noise canceling technology, but they do offer very effective noise isolation. Even when the music is comfortable levels you will struggle to hear the people around talking. I was very impressed by the amount of ambient sound that I couldn't hear.

Comfort - Easily the most comfortable headphone or earbuds that I have ever used. The cuffs fit the ears snuggly but feel like giant puffs of cotton strapped to your ears. The band does not pinch your head - no points to poke your head or hard plastic to rub against your head. In terms of comfort these are the top-of-the-line.

Durability and Fit- Very solid construction no sign of flimsiness (If that is a word). In my opinion the feel much more solid that the Beats Studio - I am very impressed.

Wireless Functionality - Probably the main reason why you will spend the extra case to buy the SMS Sync by 50.

+ Good build quality, durable
+ Comfortable
+ Sounds good (I'm not an audiophile though)
+ Buttons for muting, turning on bass-boost work well
+ Cable is nice to have as a back-up
+ Range is great

- Headset turns on in sync mode and transmitter turns on into already sync'ed mode(?). It's confusing but the reality is that I have to hold the sync button down for 3 seconds every time I turn on the transmitter. I can't imagine if there we're multiple transmitters around...
- If you mute the headset more more then a few minutes they turn off and you have to turn them on and then resync again.
- Battery life on the transmitter dongle not as long as the headset themselves and can not me used while plugged into a charger. I can listen to the headset all day (presumably the 17 hours they claim) but the transmitter last for about 8 - 10 hours.
- Signal drops a bit if I'm walking and the transmitter is in my pocket. If I put it in my jacket or shirt pocket it gets significantly better. Stationary they are really solid, only one or two pops a day. It's weird because I can hold the transmitter in my hand and wave it around like a mad-man and it's fine, but just walking causes pops.
- Plugging in the cable will boost the volume a ton if your not careful.

Overall, I like my headset but as a product there are just too many little things that are annoying and add up to give it anything more then 3 stars. If they update the product so it remembers what it's sync'ed to and fixed the audio pops while walking I'd buy them again in a minute.

The bottom line for me was first and foremost WIRELESS IS A MUST, after researching reviews, multiple sites, and I went to in-store demo stations where they let you try different brands like Beats, Soul, Bose and so on. The wireless headphone prices were crazy. SYNC is the only top notch wireless headphone I found not pushing 300 bucks, the most comfortable headset I have ever worn, if needed I can even wear them with my glasses on. They're sturdy in case your clumsy like me, the sound is way way better than Beats, or Soul. The Bose headphones that cost a little over twice as much had great sound but not worth the difference and don't look as cool. They come with a little transmitter that you connect to any device with a headphone jack and then you link it to the headphones by pressing a button on both the headphone and the transmitter. This is my second pair because I found out you can SYNC these with other SYNC head phones through the same transmitter. For example, my girlfriend and I use this feature for late night movies, video gaming, sharing each others music. The new ones don't have this feature from what I saw, and the transmitter which is no hassle at all makes for a noticeable increase in effective range its a shame they discontinued it. I purchased 2 pair for 300 dollars plus tax. That's a lot of money, to me anyway, just for a couple headphones, but I'll never have to buy another pair again (knock on wood). I feel good about this purchase, and if you enjoy using headphones for whatever reason on a regular basis...GET THEM. Hope this helped.

I'm not sure I can add anything here that others haven't already said in detail, so just briefly...


Styling is awesome. The headphones look great. Very stylish.

Unbelievable comfort. The ear cups on these are covered in a soft, soft leather that is "like buttah." They provide comfort beyond any headphones I've used before.

Sound is also unbelievable. Really, clean, crisp sound, with great fidelity, and with the bass boost, sound is full and robust.

The wireless range of these things is amazing. Great sound even from a couple of rooms away. They don't work all throughout my home, but that's fine with me. I can connect them to my iPhone or home stereo, and have the mobility to do housework or any other tasks around the house that I need to, as long as those tasks don't take me too far away from the transmitter. I suppose that if you wanted to connect these to your home stereo, then go out and do yard work, you might be disappointed.

The carrying case is so convenient! It's a great design, looks great, and holds everything you need for these headphones. A big plus for the product.


As others have mentioned, the controls don't work wirelessly. While I understand why this is, it does seem like for wireless headphones, it's a pretty big glaring problem. Some have said they've been able to get the controls to work in some situations, but I haven't yet figured out how to do it. Volume does work, but not well, and bass boost worked. Advance/Reverse did not work at all. Seems to me It might have been better to just have left those controls off the unit, then to have a bunch of irritated customers who want those features to work, but can't get them to.
