These are treated strings, not coated, and amazing.
May 19, 2022
I felt I had to put this in the title because if the review below. These are NOT coated. There is no coating that frays off. It's impossible as these are chemically treated. I'm not sure what he's using, but not Martin 2.0s, as they're not coated. Which is why they sound so good, and yes blow away the Dadarrio treated and especially coated strings IMO. They sound identical, dare I say better somehow, than the regular authentics. Even as a Martin guitar owner and huge fan, I not only always hated their strings, but any coated ones in general

Now coated lasts longer, but sounds worse, and has material that eventually comes off, etc.

When Martin developed their own treatment and introduced the 2.0s , you could immediately tell these were different. Not just the longer life and unnoticeable treatment, but their new core ratio, wraps, etc, are all just a huge improvement. They are warm, yet clear and loud. They don't have that terrible string jangle, yet they sparkle, hit their stride and stay that way. I'm a string nut and usually only use GHS Americana or Newtone masterclass, etc. I never bought cheap strings. But these Martins have become my favorite phosphors. I never thought I'd say that about their strings.

Again, these are treated. Just like GHS Americana aren't coated but treated with a cryogenic freeze, these are treated with a chemical treatment. I've beat on these and had them in forever, trust me, there's no fraying or material that comes off. It's in the metal.. I hate to keep saying that but it was extremely odd to see someone write it. Anyway, give them a shot, you won't be disappointed IMO.

Martin makes competitive coated strings!
December 12, 2021
For the last couple years, I’ve been comparing these Lifespan 12-54 against other coated phosphor-bronze sets: D’Addario EXP 12-53 & D’Addario XT 12-53 & D’Addario XS 12-53 & Elixir’s Light nano set.
These Martin Lifespan strings have given me no issues, except that my low E string bridge pin doesn’t quite want to press all the way in (due to being cut for a 53 vs 54 gauge string). I didn’t think that small variation would matter, but it seems to!
Even with the bridge pin slightly protruding higher than the others, these strings sound great and have lasted quite a long time without degrading in tone or feel.
My pick eventually does cut up the coating, which visibly frays and starts to dull the string sound. But, this is after much time and use.
I like the sound and feel of the strings, and will now be comparing them to the new D’Addario XS strings, which claim to survive picking better than any other string, while using a thinner coating. We shall see!

At this time I can report that I like the Martin Lifespans fairly equally to D’Addario EXPs, which sound and respond better (in my experience) than Elixir’s comparable strings.
I have not yet concluded my XT and XS testing to compare, but I expect them to perform as (or more) durably as these Lifespans. I anticipate the XS strings to sound and respond more like uncoated strings than the others listed above (including these Lifespans) while potentially surviving more punishment from my pointy Dunlop Primetone Flow plectrums!
I’ll review the XS performance on that listing after finding the results.
I have been pretty satisfied with these Lifespans, but not blown away in comparison to D’Addario’s coated offerings. They’re competitive and if you’re a Martin lover, these are an easy set-it-and-forget-it option that give a longer replacement cycle than Martin’s uncoated strings without sounding completely dull. You can get a still good low-end brassy growl on these until their coating starts to fray. However, you’ll definitely also want to try a set of D’Addario’s coated strings to pick a favorite based on their response with your own guitar, picking technique, and sound preferences.
I found Lifespans to be pretty stable for intonation and gradually become less strident/bright in tone through use (wear at the picking location). D’Addario lights may have a touch less power (fundamental frequency) on the lowest string. They both respond well and sustain well on my guitar, with the D’Addarios remaining extremely stable with intonation.

[For reference, the strings mentioned here were all installed on a very fine Larrivee LV-10 (sitka & EIT) built around year 2000. The guitar has a TON of rich mid-to-high overtone presence and excellent string-to-string balance with good dynamic range and sustain. Most strings sound pretty good on it, but the timbre does noticeably change with different strings. These changes in overtone prominence are difficult to express in a written review…. Larrivee calls for D’Addario 12-53 gauge phosphor bronze strings. Bridge pins are ebony (like the bridge).]

Very nice strings

Tried these strings on for the first time and so far I'm really happy. Been using the previous version of the Life Span strings for several years and I can tell these are a step up.
  • Great sounding strings
  • Stays in tune
Great strings

Love it! Sounds better than Elixir's

Excellent strings!

The first thing I want to say is that I bought this string set just to try it out. I?ve been using Elixir?s for the last 8 years and was a bit skeptic about these ones, but decided to give it a chance anyways. And WOW! They?ve won me! It?s been over a month now playing my guitar in a daily basis (that?s what I do for a living) and it still sounds amazing!
The first thing I noticed when putting these strings was that my guitar?s sound was fuller, with a more pronounced bass and more balanced mids, compared to Elixir?s. It is just like everything is in its right place (highs, mids and lows). I was, then, surprised and glad at the same time, but decided not to have an opinion till I had played with it for at least one month, to see it they would last as longs as my Elixir?s. And I?m happy to say they do last long! It?s been more than one month and there?s no sign of rust in any of the strings. The coating does its job pretty well.
For me, they are now a good option, and along with Elixir?s, are the best strings I've played with!
  • Clear Sound
  • Last long
  • Cheaper than Elixir?s
  • None

Martin MA540T. Impressed. I like this version.
October 17, 2018
These are interesting strings. In the first instance, I can tell the quality is better. The unwound strings are plain, and I had to adjust to not having Martin’s traditionally bronzed strings. However, all 6 strings feel smooth and the plain stings not as sticky as bronzed. They tune up fast. What’s most apparent is the wider frequency range in this version. There were more mids as opposed to scooped. There were higher highs and yet not tinny (I did pay a close attention to that). And, there were more bass sustain, tighter, yet not boomy as with the previous version. Overall, I like this version. Impressed.
  • More mids, tighter bass and higher highs. Overall wider frequency range. More sustain.
  • Not sure if I like the plain strings being tinned. I am so used to Martin's bronzed strings and not many companies has bronzed plains. That said, it is not as sticky as bronzed.
