Martin MA150 Authentic Acoustic - SP - 80/20 Bronze Medium ( 13-56 )

Seem decent quality, live performance guitar user very happy. Pointless buying super cheap no name / cheapo brands when these are such good value.Can't speak for longevity or tuning stability yet.

I’ve used Martin strings for years. Great time from them, easy to install. Good quality material. They look and sound brilliant. I’ve tried other more expensive brands but keep coming back to these ones. Stay in tune and feel good on fingers. They don’t seem to break as quickly as other strings.Fits acoustic guitar not to heavy gauge. Useful when performing unplugged

Good sound.

Great value and delivery promptly. Excellent sounding phosphorus bronze strings. Retain their brightness for a good period of time.

Good quality and produce a deep and bright sound. I will buy them again.

Really good feel to these strings and excellent sound quality.

Sound mega on my Martin and stay bright for a long time.

Having been using the strings supplied with my guitar i was very impressed with how much difference fitting these strings made I’m just a beginner and was pushing hard on the original strings but now find myself not having to press so hard

Sounds better than more expensive ones I've bought

The media could not be loaded. Other than occasionally assisting on acoustic at church, I mainly play my Martin guitar around the house for my own personal enjoyment.I just put them on this morning but they tuned up quickly. I did stretch the strings a few times after my initial tuning and had to adjust but since then, they've maintained their tuning.I had them on my guitar, tuned, and playing within minutes. I leave my guitar out on a stand in my music room. I know I should house my guitar in its case when not playing but I like to have it within arms reach. I can't speak on the longevity since I leave my guitar out and that will have some effect on the sound and tuning aspects.However, they sound great right out of the package and they're offered at an affordable price too. I like having these authentic Martin strings on my X-Series guitar. I'll continue to order more as needed.

Gooooooooood
