A glowing reference!

I consider many options, read a lot of reviews, did a whole research, I was looking for something that could reach my standards. After more than six months of use and new options out there I would still buy these. To begin with, Sonic Electronix offers an unbeatable price and ships without issues. You get the value for your buck. I’m really amazed, the 18 ohms impedance matched with the noise isolation allows to listen even at the lowest volume set. It’s true that you experience each and every single instrument, honestly, like listening to your music for the first time.
Some facts: 1. you might have a hard time for them to fit your ears, but that’s solved with the right tips, 2. if not fitted properly you would miss bass, that if you actually notice, we’re talking about the bass you miss with most commercial headphones anyway, 3. they give you a fragile feeling… but no, they’re not that fragile, the new cables with built-in strain relief really do their job, I’ve been using them everyday to deal with public transportation, they don’t have a scratch, and no, the cord doesn't get tangled 4. the only issues you get are those for any other in-ear, but these are the only ones who would match, if not beat most speakers.
They sound so natural I usually find myself forgetting I’m wearing them, they’re really light but they can sound like a concert. You would never look back, they’re indeed a reference.
P.S. the case is just the right size as you can check on any picture, but it has a custom size foam inside which you can actually take away if it gives you any trouble…

Klipsch Reference S4i In-Ear Headphone

I bought these headphones because my other headphones wouldn't fit in my iPhone headphone jack with a case on it. It has been almost a year since I purchased these and they are still great. I like the built-in microphone for making calls, people can here you without having to move it close to your mouth. I like the sound quality from the speakers good highs and lows, just make sure you choose the right rubber adapter for ear. Overall I'm very happy with them and would definitely purchase them again.

COMFORTABLE EARBUDS !!!!! EXCELLENT SOUND !!!!!

Let me just say that these earbuds are the only pair that fit my very very small ear canal with the tips that come on out of the box. They come with a total of four from really small to larger. They will definitely fit all ears. Not like all the other'd out there that hurt your ears after 10 minutes these you will not know there there after hours of listen pleasure. Great sound reproduction from lows to highs to good bass. Very light so very comfortable. Good company to purchase from !! Great price and fast delivery. Buy these buds from this company an be happy listening to your music without ear pain !!!!! Thanks !!

Incredible sound

These headphone have the most incredible sound. I had the regular S4i headphone before trying these. No comparison, these are significantly better. Glad I upgraded, no regrets.
