More Tone Range from These
583285
I installed these on a Jackson RR1. No problem fitting them in the control cavity. The tone pots now have more range with these capacitors,  much more range than with the tiny stock green ones. I am satisfied.

It was unfortunate that there was limited availability on the black cushions, but with the silver plates on my LP2s, these do not stand out too bad.

These DO make for a different listening experience than the standard cushions.

PROs:
-less heat
-greater overall comfort
-more space for your ears
-increased listening sessions

Not-quite-a-con:
-These do not seem to insulate external sounds as well as the standard cushions (IMO)
-They don't look as chic.

Overall, upgrade if you have big ears or listen for 2+ hours at a time.

These sound great using my smooth jazz and classical selections. They are best on a powerful amp like the computer or player as they need to be cranked up. Not as good on an MP3 player. They fit very tight and I bet will cause me to sweat if used on a warm summer day. I tried some more expensive ones at Costco this week and these were as good but the Bose were more comfortable.

I love these speakers!  They sound so much more than their size and clear at high volume.  I'm driving them with a NAD D 3020, which could use a little more power.  I have to run the amp at high volume to fill the room well, but it is well made and can handle it.  I might upgrade to a surround setup and get the uni-fi center and a Sub.  Bass is really nice but is missing that thump in certain music and movies, but otherwise , clear at low volume, funky at high volume speaker.

These sound amazing! Installed these in the dash of my chrysler 300. I did have to turn my treble down from flat to -3 (out of a total -9) to compensate for the highs being much louder. I may be able to turn my treble back to normal after replacing more speakers (6x9s in my door and rear deck)

The more I listen to these speakers the more I like them.  I've used the Altec ACS30 system for several years, and it produces very clean, satisfactory 2.1 sound.  When I realized I was spending way more time listening to music at my pc desk than through my living room stereo, I decided to seek something a bit closer to an audiophile-grade set-up.  When I first heard these Logitechs I wondered about the midrange issues mentioned in several reviews here -- these speakers didn't seem as bright as the ACS30's out of the box.  But I soon began to notice new layers of sound and musicality in the mp3 collection stored on my hard drive, as if these speakers had opened up a wider tonal range rather than just a more insistent midrange.  Within a couple of days I realized my onboard AC97 audio wasn't quite adequate any more, that these speakers really showed up the limitations of onboard audio.  Therefore, keeping with my goal of a truly hi-fi listening experience, I've ordered the Creative X-Fi Xtreme Music card and I'm eager to hear the result.  But these speakers by themselves will make you hear your digital music collection with new vitality and subtlety.  I don't play PC games -- just music, so this 2.1 system is perfect for my needs.  I was happy with the Altecs, thrilled with the Logitechs.

Nice low range coverage. Takes a little more air to play, and tone and is not as bright as others.

I put these on my Taylor acoustic and they have lasted and the tone has as well which I have not had with other brands. They also sound awesome I am sure that you will agree. Give these a try for sure.

I bought these after using daddario 009s and these have a much fuller sound and can stand up to my bending without breaking. A 3 pk for this price is a bargin.

i had hertz but i didn't like them because they had no bass at all. the tweeters were very loud though. the alpines are pretty nice. they sound great and produce some bass. if amped im sure that would show the full potential

These do a pretty good job.  The highs are very crisp and the overall mid-range is excellent.  The bass is not spectacular, but about what I expect from a 6X8 speaker.  I like the adjustable gain on the crossover, but I set mine at +3 before re-installing my door panels, this was a mistake.  Set them at 0, especially if you are playing MP3s or you may find the tweeters too brilliant.  When the weather warms I will be adjusting mine.

I upgraded my front speakers in a 2003 Taurus, along with installing a MACH amplifier, the added wattage really made these sing.  If the bass were a little better I would have given them a 5 star.

But for sound reinforcement enthusiasts, I'm not convinced they're the way to go.  They tend to knock out the midrange, which I'd rather do through my equalization circuits.

But they are well-constructed.

Wasn't expecting much sound quality for the price, I really like the sound from these considering what I paid.

In the equalizer (foobar2000) I find myself lowering the 1.8kHz and 3.5kHz a little bit (about 3dB) and the 2.5kHZ a bit more (6dB), this is fresh out of the box so maybe some burn-in will help (see 'edit' below), and of course a lot of music doesn't hit those frequencies the same way so it's usually no problem.
The bass from these could be slightly stronger but for the price and form factor (non-canal) it's great and better than I could have expected.

I just needed something to replace the completely horrible ear-buds that came with my 3 year old sansa mp3 player that were also not in-ear canal (I like MEelectronics M9 a lot but they are tough to keep in properly while I'm active) or full-size/over-ear headphones like Sennheiser HD201, which these sound similar to and in my opinion these sound slightly better with HD201 having slightly less bass and a bit to much treble compared to these.

few-days-later-edit:
After letting music play through these for probably 60-ish hours (at slightly higher than normal listening volume) it seems to have softened the 1.8khz/3.5khz enough that I find no need to adjust them and the 2.5khz range still needs about 3dB reduction for a particular song or two. Not enough of an issue to bother with, though.
Still very happy with these, no problems so far.

If you have a Grado sr80e you should use them, improve the sound a lot: better bass and greater clarity

I've used other brands but I can hear a lack of static/feedback/impedance with these.  A clarity I didn't think was achievable.

these are of a somewhat higher quality than most, for only a few more bucks

Not quite the brightness that I like but, these guys articulate well and give a solid tone. I play mostly a Rock genre music. Say, ranging form a jangly Television sound to something awash with distortion. When I get really distorted, these guys let the sound get muddy. Now, distortion already tends to make things muddy and these strings just didn't have the ability to rise above it. I do like them for most other types of playing. The Blue Steels sound full and have a nice broad tone quality except at the very top end of brightness. They are definitely worth a try if you're experimenting. I've had no problems with durability and duration of usefulness. Good luck!
