Possibly the most hit and miss strings on the market
I've tried every set of D'Addario's Titanium strings on a variety of instruments (all solid, solid top, lamintes, banjo ukes) and have been alternately pleased and frustrated with the sound. Of the 12 sets I've purchased and installed, 3 instruments sound great, 2 sounded passable, the rest pretty lousy. When I broke a string on one of my ukes that sounded great with the Titaniums I restrung it with another set. I was shocked at how awful it sounded and they were the exact same set as before. Their baritone sets are particularly bad imo. I've installed them on 2 different baritones and both had the exact same faults-weak, dull sounding B & E strings, and probably the clankiest, noisest, abrasive sounding D & G strings I've yet to experience. I'm not exactly sure what's up with D'Addario and these strings. I'll probably still take a chance on them if the price is right i.e. Under $5 or free.
ProsThey're usually pretty cheap.
The purple colored strings look cool under the right light.
Baritone strings are particularly disappointing.
