Klipsch knows how to screw it S4
593554
Klipsch S4 series was great, I got R6 as replacement warranty for S4ii.

wearing for a day one can tell the great design flaws in R6, not sure how Klipsch 's designers could have missed this so badly. Lost respect for Klipsch.

the wire is thicker and heavy, the volume controls hangs below the left ear buds and that too is heavy. the end results is the heavy wires and controller pulling down the ear buds, apart from causing disturbances.

All klipsch' need to do is use better materials for S4 wires.

Amazing Sound.  Durable construction.  Great buy.  Works well with Samsung Galaxy S4 using NFC.

After Listening to all the logitech and Insignia (and my own logitech)units at Best Buy I came to this klipsch unit was BLOWN AWAY. THX certified for a reason I guess....its just an orer of magnitude better than all the others. All of the other units had a hole in the midbass and no real low bass. These do a geat job of filling in the mid bass so voices sound warm clear and real. I prefer bass reflex over ported units but this one is quite good. The highs sparkle, the bass is real and I could not be happier.

**UPDATE** 02/03/2013

I felt it was a  bit biased to rate this item two stars because of my bad experience with Klipsch so I revised my review to reflect the product accurately.

**5 STARS** - Klipsch Quintet 5.0 Series

These speaker are the best you can buy for the price, period. Right now for under $300 a set on Amazon, you can buy two of these sets for the price of their own original MSRP which is an absolute steel at this price. Let me rephrase this for people who are looking at purchasing a set right now. THERE ARE NO BETTER SPEAKERS for the price. We bought two of these sets for 9.1 set with a Pioneer Elite SC-68 Receiver. We have fronts, sides, rears and front height speakers paired with a Klipsch SW-350 Subwoofer and are currently witnessing "Audiophile" sound. This is likely due to the accuracy of these speakers and paired with a perfectly calibrated sound stage with one of the best receiver's you can get, which is the Pioneer Elite Series. The surround sound that these emit are total chaos, you hear thing's you've never heard before and they can get LOUD.

**1 STAR** - Klipsch Customer Service

Klipsch, when talking to a few of your representative, I was completely dissatisfied with how they talked down to me. I hate to tell you, but I know 5 times as much more then your front line reps. First no one even answered my sales or support inquiry (right off the bat, you lost business due to slow response time and un-knowledgeable staff). I inquired on how I could buy 2 pairs of additional Speakers for a 9.1 sound stage and was basically laughed at like I'm some idiot (I'm a hifi pro-audio enthusiast). Unfortunately, I have a small house and having these speakers, but in a 7.1 or 9.1 configuration matters for me, and my neighbors, who have the same set we do and live in a similarly sized home. I built the sound stage before my house was completed and spent hours calibrating the audio. PEOPLE WANT ADDITIONAL SPEAKERS Klipsch, acknowledge this and sell these speakers as separates. I refused to give your company until this was resolved. Fortunately, Amazon lowered the price of this set $274, which means I could buy two for the price of one basically so instead of waiting and messing around while you guys take your time to release additional separates (like the last two generations of Quintet's), I just went and bought two sets and discarded the 2nd center channel. Either way, you guys got to get it together, people care about your professional audio products, but they will care less when they get treated like retards when they are trying to give your company money. I'll stop raving about your products if this ever happens again. I really want to enjoy/ like your company, but your guys are makign it very difficult for me to do so.

Overall, great speakers - unbeatable for the price, but beware - customer service from Klipsch - might make you think twice and leaves a lot to be desired. This wasn't my first bad experience with Klipsch (that's why one-star) , but you can catch that on my other Klipsch reviews.

Why a full 5 stars? First is the sound quality The the Klipsch Image S4A sounds just 'Amazing'
I previously was using a pair of JVC HA-FXC51 which sound great on the bass but I didn't truly notice how warm and full the mids and high sounded until I put on the  Image S4As. In fact after using them I gave away my HA-FXC51s to my little sister. I immediately fell in love with these phone and I will never go back. The flat cable and case have now become a staple in my must carry items (keys, wallet, cell, headphones). On terms of sound and comfort great, and the different sized buds are certain to fit your ears. I like the standard size the best. Now onto the reason that I bought them. I wanted a great pair of buds that I listen to music to but at the same time make a phone call with the integrated mic. I skype just about everyday on my smartphone.

There are only two items that didn't work as quite well. First is the microphone falls about half way chest and requires me use the actually clip to make sure it props closer, because there are times where the microphone doesn't pick up my voice. It works quite poorly if you run the wires and microphone underneath clothing. Again this isn't a design failure it's just the microphone isn't 'perfect'. Secondly was the Android app didn't work from my Sprint Samsung Galaxy S2 (I think it's because i'm running 4.0) and the app isn't compatible. But the buttons just works as a standard button with the app and starts and stops music from my Google Music app.

Lastly, I wasn't the only one who loved them, so did my cat and after discovering one night on the coffee table decided that it would great to chew the cord up. Only two weeks of ownership and the cord was destroyed, even though the pair ran me nearly $100 I loved it so much that I had to immediately buy me the replacement pair and make a mental to note to always put the headphones back in the protective case.

Pros: This replaced a KLH 12" sub which was rated at 200 watts in a 25' x 35' open room. The 300 watt Klipsch is vastly superior. The greater wattage delivers not mere volume, but crisp control of that big speaker cone. Musically, it delivers not only the notes, but the physical punch of kettle drums. Organ music smoothly reverberates the room. Playing rock, the bass line comes through cleanly, without muddling the lead guitar. Movies often have a deep, building bass note at the points of highest tension. I can now feel these notes as if I were in a theater. Almost any low end sub can do the thump from big explosions, but you may never know how much else you are missing.

Cons:  Given Klipsch's high reputation among audiophiles for manufacturing quality products, it is amazing that they ship these units in boxes suitable for junk. Single wall cardboard with 4 thin Styrofoam corner strips which offer minimal shock absorption. No protection for the feet. No moisture protection. Easily punctured. My sub arrived without damage, despite some holes in the cardboard. I feel like I simply got lucky. Klipsch, put a couple more bucks into your packaging to protect your reputation for quality. Be sure to look for the 4 adhesive rubber foot cushions in the plastic envelope in the box. They fit recesses in the speaker feet, and are essential if you are setting your speaker on a hard floor surface.

Other thoughts:  If you find that your sub has "holes" in its frequency response, or notes that just take off and overwhelm everything else, the problem is not with the Klipsch! People seem to assume that because bass frequencies are omnidirectional, and this woofer is down-firing, they can just stick the sub anywhere in the room. Every room has unique harmonics based on the interaction among wall and floor coverings, room shape, ceiling height, openings and furnishings. There are no practicable "rules of thumb" for placing a sub. No one can determine the best placement point just by looking at the room. There is good info on the web about how to audition your room for the best placement of your sub. You can get an MP3 file with test tones. A little research and experimentation is well worthwhile!

This speaker is a great deal.  Don't listen to the audiophile snobs posting bad reviews.  Klipsch didn't market this bluetooth speaker to compete with expensive high end reference speakers.  At this price point, thats pretty obvious.
I have a Bose Soundlink Color and I tested them side by side.  The Klipsch Groove produces rich, clear, quality sound that, in my opinion, is almost as good as the Bose.  At this price, this speaker is a bargain.
I did notice that this speaker works better from across the room rather than close up.  If it is close to the listener and the speaker is angled even a small amount, the sound quality decreases.  Placing it farther away results in a greater angle where the sound is high quality.
From an operational standpoint, connecting to this speaker was simple.  Within 20seconds of starting the pairing process I was listening to songs on Pandora.
I am very satisfied with this purchase.

I got a set of these with my Galaxy S1 (the one with that fancy Wolfson audio processing system).  It sounded better than my iPod!

Samsung must have really wanted to emphasize the audio on this phone, because they included the best set of in-ear headphones/earphones/earbuds that I've ever used. Period.

I've tested these out head-to-head with some fancy earbuds from Sennheiser and Sony, and they were absolutely unmatched in audio quality.  They're amazing.

I just bought two more pairs, as at $4 they're an incredible deal!

Previously owned the S3 ear buds, which were good, but they finally pooped out.  Based on multiple reviews online, thought I would try the S4s.  I have to admit that I was pretty impressed from the get-go.  Great overall sound that continues to get better and better with age, as they do appear to have a break-in period.  I have allowed several people to borrow them to compare to their ear buds, and the S4 has won on sound quality and comfort every time.

I have always admired Bang & Olufsens design aesthetic but never owned any of their product. When the S3 hit $118, I took a chance, sound unheard as it were. The purpose of the purchase was to provide some background tunes for the kitchen. What was totally unexpected was how it would FILL the kitchen (and dining room, and hallway) with glorious music! This is one serious speaker!

I hung up my audiophile hat a while back because life is too short to fret about cables and power conditioners and trying wring the last minutiae of soundstage from my system - I now just sit back and enjoy. That being said, after 40 years of purchasing components, I know good sound when I hear it and the S3 delivers and then some.

Ive read (and watched) some disparaging reviews Regarding the S3 and this is what I have found out from my own experience: If one feeds crappy music to the S3, that is exactly what one hears. The S3 is exceedingly accurate. Dont expect a low bit rate mp3 file or, say, Pandora on its free stream to magically come alive and sound great. But give the S3 Tidal hi-fi or Spotify hi rez files and one will be greatly rewarded. Also, do not expect booming bass as the S3 does not try to compensate for its 4 woofer by boosting the lower frequencies. The S3 is rated down to 42hz and it drops off sharply after that. Fortunately, there is a line out so one can add a (quality) subwoofer if so desired. I can only imagine what a pair set up in a 2.1 configuration would sound like (pretty awesome, I am sure) but for now a single S3 is more than enough for my needs.

At its original $300 asking price, I would give the S3 a hearty recommendation. At $150, I defy anyone to find a better sounding, self-powered speaker, it is that good. At any price lower, it is an absolute steal!

Quick edit: Not much has been said about the Beoplay app. Not only does it control volume, but the sound signature can be tweaked to a degree. I prefer the factory flat setting, but if a recording is too bright (not the S3s fault!) it can, through the app be adjusted to a warmer sound signature. The converse is true. Note that the app does not boost frequencies like traditional bass and treble controls but shapes the sound by reducing certain frequencies through the onboard DSP.

I had been looking for a good pair of earbuds for a while.  People seemed to really hate on the Klipsch s4i specifically related to their reliability.  I kept searching and started looking at Ultimate Ears etc but they didn't have the integrated remote.  Then I found Klipsch's 2nd revision and the new product the X7i.  I have to say I am impressed so far.  The new flat cable design makes sense and I'm glad there are no tangles.  The actual buds are very small and look great.  The remote works great with my iPhone 5 and the sound is impressive for how small these things are.  People apparently are concerned about the bass but it's just fine unless you are a person who rolls around with a pair of 12" subs in your car.  Get yourself a pair.

BTW, I rated them a 4 because I haven't had them that long.  If they hold up I'll upgrade them to a 5.

I am now almost onto my third pair of these.  The first time one of the earbuds started getting fuzzy and I initiated a warranty call and Klipsch took care of me although it did take some time.  The second time one of the buds just completely stopped working which is why I did another warranty call.  I'm still waiting for the next set to come in but I can no longer recommend them even tho I love the form factor and features these offer.  Each pair has lasted for about 6-7 months before flaking out and I take very good care of them.

I bought these a few weeks ago for $95 during the black friday sale. I've owned s4i's for about 2 years now, and they, as the customer reviews will oblige, are absolutely fantastic value. Its the same story here since amazon has dropped them by over $200. $140 right now is a very good price. They come with all the accessories you would want and they are incredibly small. Sound quality is as good as Klipsch says it is, and the fit is always perfect since the eartips, like on all Klipsch earbuds, take the shape of your ear and there is very rare adjusting ever, if any. The carrying case they come with is very compact and nice. Its faux leather and closes magnetically and theres just enoght space for the x10's after you roll them up. Overall, especially at the current price, these are truly great headphones. if anything, wait another month or so and get them for even less.

I have a Samsung Galaxy Nexus, so if anyone is curious the pause/play (double-tap for next) button works on Android phones.
Sounds great and the seal is pretty good on my ears, comparable to Klipsch S4s with significantly more bass and a little less treble clarity (but not too noticably different)
The shirt clip is nice (and necessary) because the flat cable and well sealing buds will cause a lot of the internal noise expected from the seal (e.g. your own chewing or cord bouncing/scraping)

My first Klipsch product..and I've longed to own their stuff for years. This  is one heck of a great sub!  As with any subwoofer, careful tuning to match the rest of the system is required, and after a phone call to Klipsch tech support, a 24 hour break in period doesn't hurt either. That is,  24 hours of moderate to low volume use to loosen the surround before really cranking it up. Klipsch has long been known for their incredibly efficient speakers, which means they can play louder with less, and this sub is case in point. After all of the tuning and adjusting levels, I was pleasantly surprised and  how this monster is a highly musical subwoofer if tuned properly, and adds weight, scale, and muscle to any music I give it.  Its class D amp (digital) at 200 watts RMS, and 400 peak, allows for it to be lighter, and create less internal heat. It effortlessly pressurized my listening room with power in reserve...for under $500 you can't beat this one...

I purchased these buds on a whim when I needed to listen to my Sony Walkman MP3 player. In short, these buds are decent for the price. Since I'm an audiophile, however, I love my Klipsch S4's much-much more. But at $80 a pop for what I paid for, that's in a whole different league.

Sony, keep making great products!

If you need something fast, something you can break-dance to while listening to music & not care if you yank on the cable and still sustain good audio quality, this is for you.

High's, and mid's are crisp. Even handles bass well. Easy install comes with adapters for almost any configuration. Installed straight to the deck(clarion cx501) I had to drill 2 holes per speaker to match the included adapter and that was it. I always use infinity kappa with my systems to replace stock. Never been disappointed. Worth every penny if you take car audio seriously.

Yay now I have 5.2.2 all Klipsch speakers! If you have room to fit this monster buy it! The "free" Klipsch WA-2 Wireless Supwoofer Kit is awesome! With this is a Must Buy: Monster Cable 650DCX for a solid connection to the WA-2. With this cable you won't get signal leakage and interference like I did with cheaper cables. Buy both items and you will be happy with your awesome  decision!
