unbelievable quality
ive played ernie ball 2047's S&S for years never finding a better string. i tried these (6000) on a whim and found what i consider the perfect string. every quality i want is in this string. now it remains to see the lifespan on these, but if i get 4-6 weeks i consider them a bargain. i D# tune and most strings have sound issues but not these.

Amazing Tone Matched with Great Value
These strings are by far the best on the market that provide full tone and bring the best out of your guitar while still having good string life. I use these on my Martin JCPA4 and it sounds like a dream. They usually last me a solid 3-4 months before I feel like they need to be changed. I automatically regret when I change it up with D'Addarios or Elixirs and want nothing more than to put these strings back on. Full tone, clear highs, punchy bass, and warm mids...what else could you ask for? Love them!
Pros*full, robust tone *smooth string feel *great value at price point
Cons*oxidize faster than other strings, but still worth it for the tone

Martin for my Martin!
Bought a pair of Martin X-series guitars (12 and 6) coupled with theses strings it's the perfect acoustic sound! Bright but not obnoxiously so. GOOD acoustic bass to mid-range punch that you can dig into. Only complaint: string life is a little bit shorter than should be for a coated string, could be cause I'm just playing more though!

The Best Out There
I love these strings! I did some research to see what kind of string may sound the best on my Martin D15M (all mahogany) guitar and saw that the 80/20 alloy brought out the top end of guitars and decided that that was what I wanted out of my instrument. After putting on these strings, I heard the beautiful tones that I had never heard from this guitar before (I was using Martin Phosphor/Bronze). The tops chimed and the bottoms brought out the boominess of the dreadnought guitar. It felt as if I had gone from the Dark Ages directly into the Atomic Age and beyond. And they last, boy do they last. The Cleartone coating is marvelous and they don't even feel like they're coated like their counterparts in the industry. They are so good that when I had my guitar set-up, recently, the Luthier was going to put D'Addario strings on at no cost and I brought him these string to put on instead. I am officially sold on these,there's no more shopping around.

very good strings
I'm not particularly brand loyal, and go through a lot of different strings, but have found that these Martins produce the best sound for about 1/2 of my guitars. They do last longer than other brands (although not quite as long as Elixirs), but it's the the intonation, tone, and feel that keep me coming back. If you have a guitar that sounds a little stiff, try these out! Worked great on my Collings! I do change out the high e and b strings for a 13 and 16 to achieve more of a "true medium" feel with fatter trebles, but it's not necessary.

Great, reliable strings.
I've just put my third if these on my Ovation Legend LX. I won't use any other strings for my Ovation. I've used Elixir, D'Addario, real Cleartones, and DR Dragon skins (which in my opinion, were the absolute worst). I was looking for a string to replace the SP+ Martin that got discontinued. I have a heavy hand when it comes to playing and I've never broken one of these strings. I replaced my strings only because that's what I do after 3-4 months. Even after 3-4 months, these Martins sounded great. Nice tone and reliability are what these strings are about. I rarely give anything a 5 star rating, but with the luck I've had with these LifeSpan strings, I have nothing bad to say about them. Try a set!
ProsGreat tone, strength, and reliability.
ConsHaven't found anything yet.

Awesome Tone that Lasts and Lasts.... and Lasts!
Better than Elixers IMHO. These things SOUND good. I even use them on an acoustic archtop. Have had the same set on the archtop for 5 months, and they still sound new!

Martin Lifespan Sp Phopsher Bronze
Wow...just put on a set of these on my Martin DC Aura. For 4 years I had been using the recommended Martin SP4100's as per my guitar's manual. Immediately I noticed a bright clear tone from these Lifespan SP's that I didn't know my Martin was capable of. Absolutely beautiful sound from these. We'll see how long they last. I'll say it again, WOW.
