Treated with Cleartone proprietary technology to bring you the longest possible string life.
Rich tone should last as long as the inspiration does. Built on Martin's durable SP core wire, Martin SP Lifespan strings are the next level in studio and stage performance. Now with a more advanced proprietary treatment from America’s legendary guitar builder, SP Lifespan strings repel dirt, grit and other environmental elements that can quickly alter the sound of your strings. All six strings are treated to ensure a longer life. Martin developed a new and advanced method to treat strings, resulting in a process that ensures both the core and wrap are protected from corrosion. The molecular level treatment adds almost no mass to the string, will not flake or peel, and does not alter the vibration pattern like some string coatings can. The high-tensile strength SP core wire resists breakage and holds tunings longer – a perfect match to the treatment in creating a long life string. SP Lifespans are designed to last longer and sound better so you can play on.
Change your strings less often while enjoying better sound longer. Order today.

Comments about Martin SP 7700 Phosphor Bronze Lifespan Coated Baritone Acoustic Guitar Strings:
I build guitars for a living, and that has included a lot of baritones. Until these strings were introduced I really had no coated string options for customers wanting 27" scale acoustic guitars tuned C-C, 28.5" scale guitars tuned B-B (2 and 2.5 steps below standard EADGBE), and scales in between. For these scales and tunings, this set has virtually the same tension (about 185 lbs) and feel of a standard Martin-style acoustic guitar with medium gauge strings, and has the same balance of tone across strings as any good standard set. These strings are also well matched to Martin's J-28 and their Pete Seegar 27.5" scale baritone guitars tuned C-C or drop Bb. The coated baritone sets from Elixer and D'Addario's EXP line are far too heavy for these scales and tunings for most players, so the Martin SP baritone set is a very welcome addition to my arsenal of string choices.
One should be careful when installing these however as they have a tendency to break easily. If not for that I would have given them 5 stars.
