### ⭐⭐⭐⭐⭐ Best Earphones Ever!!
*by S***M on December 19, 2014*

Perfectly well made earphones!! I couldn't have loved this earphone anymore! I have tried the Sennheiser In-ear momentums, Rha ma750i, Sony Mdrxb60, and these seem too surpass all of them in sound quality(except the bass in the sony) and comfortability. They couldn't have made the earphones look any better than this. It fits well, very comfortable for over 3 hours of use, and as for sound isolation its much better than most average earphones but they also include some memory foam earbuds which totally block out any sound for people who want to use this in the gym or for running. These have a flat tangle free cord, black on one side and blue on the other. The sound is very well balanced compared to the sennheisers and Rha. The sennheisers had too much vocals with high trebles and minimal bass. Suitable for people who like fast paced music or vocals. The rha ma750 is a more balanced sound compared to the sennheisers but still lack bass and I think are slightly too heavy. The Audio technicas have smoother highs and a clear mid which you can define. They also have a nicer punchy bass without sacrificing the mid or high range sounds. I also notice the surround sound alot more in these earbuds.This earphone is perfect for people who love trance, techno, electro, dubstep, rock, and even orchestra. However it does lack a bit of vocals but it suits me well. I have never been happier with a product like this! I get alot of compliments on the looks of the earphone too. Definitely worth the buy!

### ⭐⭐⭐ It was a love at first hearing as far as the sound quality ...
*by O***O on May 13, 2015*

I bought these headphones on 15th February 2015.It was a love at first hearing as far as the sound quality goes.The first odd thing I noticed was that there was no sliding clip to hold the two wires together.I found that a little odd but chose to overlook thats the sound reproduction was excellent.Perfection: The Sound, the fit and wires (cables) that almost never tangles. I loved it.Now here is the reason for 3 star ratings. In my opinion this headphones’ Achilles heel is the unit which houses the microphone and volume control.1. I am using these headphones with iphone 6, and I very quickly found out that the volume control on the headphones did not control the volume output from the iphone. The volume slider just slides up and down as a second step controller & not as a remote control for your ipad or iphone. This is a strange design change/choice but I guess some people like it and something that I will get used to in time.2. The middle round button which stops/plays/takes calls, etc felt very strange but easy to use. However within 4 to 5 weeks, it started behaving erratically and now very often it will not respond to pressing buttons.3. I also found the whole microphone unit placement to be strange, it was too low for me and often found myself speaking loudly in order to be heard. But, I fixed that issue with tying gentle knots in the wires shorten the length and to bring microphone closer to me. And used an old clip to keep the wires hooked to my shirt and keep in place, so that they don’t flap about when I am on the phone and deafen the caller.About 2 weeks ago, I noticed a clear drop in sound quality: no matter how much I turn the volume up, it sounds like the volume slider in the microphone unit is stuck in low volume mark. No matter what I do, I cannot improve the sound quality It still sounds like the sound is coming through a tunnel. I have no idea how this happened, maybe I over used the volume slider?I live in New Zealand and Audio Technica website wants me to send the headphones to Singapore for repair and servicing.Please do not get me wrong, I am not complaining about sending the headphones to Singapore or USA for servicing as we are used to doing sending things away for servicing to Australia, USA, etc. but within 6 weeks of purchase?I am sure this is not right, surely the headphones should last longer than this.

### ⭐⭐⭐⭐ Premium headphones, lack punch
*by S***1 on December 31, 2015*

I have had a set of ath-m50's for several years, and they remain my favorite full-size headphones, so when I was looking for a new set of ear buds, I deemed the sonic fuels worth trying. Overall, they are impressive headphones. They have a truly premium feel, fettuccine-style cord, single button control for Android phones, and volume slider that work very well. The fit in the ear is very secure, and I love wearing these ones at the gym, because they stay put during even the most rigorous workouts due to the rubber rib that stabilizes each earbud. I really have never owned a more secure fitting pair of earbuds. The only reason this pair gets docked a sta is due to the sound, which surprised me given audio technica's track record. The max volume level is a little lower than other buds, and the sound is a bit flat and lacks the punch of other premium buds like klipsch, sennheiser, among others. The bass is true, but uninspiring. The overall sound is good, definitely above average, but just not as good as I was expecting. Otherwise this unit is top notch.
