Great Bass strings
I have an acoustic bass guitar and I tried D'Addario semi round strings for a 5 string bass. The B string broke just trying to tune it the first time. The E string was DOA. So I bought these strings and will pick up a single B string later. These strings play really nice. Nice and mellow yet louder than the original round wound strings. Would definitely buy again. No loud zipping sound when you run your fingers up the strings. They are probably not for an acoustic bass but I made them work.

Really liking these. Great E string tonal quality.
I have a through-body Mustang bass. Since I bought it, I always used LaBella Mustang Flats because of the perfect fit... I'm surprised more strings don't market specifically "for Mustang". But these strings, in the medium-scale set, are PERFECT for a through-body Mustang. Also, the sound is excellent. The E string has (at least on a brand-new set) just about the liveliest sound I've ever heard on an E string. Ya know how sometimes playing a note on the A string vs the E strings, even on a brand-new set, sounds way, way different in tonal quality? That problem is really minimized with these strings -- again, at least on a brand-new set. I'll be keeping any eye out for how the E string deadens with time, but as I get a better ear with time, I find that I need to replace my strings about every 3 months anyway, otherwise everything starts sounding dead to me. Too bad Thomastik-Infeld doesn't make their Jazz Flats in a scale for through-body Mustangs, those suckers sound good forever! (hint hint, T.I.!) Anyway, these strings seem to have noticeably better sound than the LaBellas, especially on the E. I really like the gauge too, they just feel right. May have to become a lifelong d'Addario fan! ADDENDUM AFTER GOING THROUGH SEVERAL SETS: Still loving them! I usually get 3 to 4 months on a set, and then the dullness starts to kick in too much. Although even after 4 months, you might really like the sound, they still sound good, they still play well, and they still stay in tune -- they just don't have that lively bright quality like a newer set. They also age very, very nicely, in that each string ages equally, even the E string, which is really surprising since I've found that the E string (with other brands) tends to go duller faster than other strings, and gets to be way-too-dead very quickly. Not these babies!!! The E string, even after four months, sounds comparable in tonal quality to the other strings and still has good sustain... again, just losing that brightness to age at the same rate as the other strings. UPDATE: after many, many sets of these strings, they are still my favorite for a Mustang Bass instrument with through-body strings. They sound good for a long time, getting "deader" very gracefully, including even-balanced aging and tone on the low E. They sound so good aged, that it shocks me when I throw on a new set and hear how bright they are!! I'm like, whoa, sure, they weren't bright after all that time, but man they still sounded sweet!

Awesome strings
I put these on my Ibanez Mikro and I could not be happier with them. They sound incredible and fit great. I like smaller, lighter instruments for writing at my desk, so it's nice to have high quality options for a tiny bass. I initially bought the Mikro because I was experimenting with bass synth, and I thought the shorter strings would be easier to calm down between notes, which would prevent confusion in the processing of the synth effect, and that turned out to be true. With the flatwound chromes, it seems a lot easier for the bass synth to process due to fewer harmonic overtones and more controlled string vibrations.

Great string upgrade.
Got these for my Squier Bronco Bass. Did not want to spend $40 on strings, but man they have made such a difference! Tonally, more definition, smoother sound like what you hear on the original recordings, and smooth silky feel. Sounds almost as good as my regular scale bass.

My favorite flats by a mile
For me, Chromes are the best flatwounds out there. And I’ve been through them all many, many times. Chromes have the smoothest surface with zero friction, and set up very low without ever having any buzz. They play very fast and work well on P or J. The quality control is extremely consistent and once broken in they sound absolutely amazing. Be sure to give them about a month before you judge them. Soon they become extremely thumpy and warm. I like LaBella too, but have stopped supporting that company because of so many bad D and G strings. The company does not acknowledge a problem yet it’s reported heavily throughout Internet forums for over ten years. The issue is that the strings will buzz no matter the action height.

Superb Full-sounding Strings for Professionals or Praise and Worship
I am a professional as well as a praise and worship player. I have tried the other popular brand flatwounds and have always come back to D'Addarios. I really like the fuller sound of D'Addario strings. Even when the bass is adjusted for a bright sound, it is a fuller, fatter bright and not so tinny. I have them on hollow-body electrics, acoustic/electrics, and high-end professional 4 and 5 string basses. SCALE/GUITAR: I purchase the SUPER LONG scale for through-the-body set-ups and long scale for standard setups of 34" scale basses on my 4 string basses. The D'Addario long scale came up slightly short and the full windings didn't even make the nut on the through-the-body set-ups. Additionally, it feels like the longer scale actually alleviated some of the excessive neck tension on 4 strings. *On some five strings I stick with the Long scale strings WITH a TTB set-up to keep the B string from feeling floppy. I had to trim some of the sring winding at the nut but this is easily done and the bass really resonds well. COMFORT: The Flat-wound Chromes are incredibly comfortable strings. If you like to slide all over the place, these strings are for you and produce zero slide noise. SOUND: I love the full, mellow sound they produce. I have played R&B, Jazz, Rock, and Country, and I also play on a worship team, and these strings can solo on the most reverent of songs, or turn it up on a good Rock riff. With the right tone adjustments on your bass, you can get a very full and balanced sound that is 'there' without being 'on top' or distracting, as well as a bright but still smooth and full lead for great jazz, country or rock. Just don't expect a great deal of growl if you're trying to slap. CONS: The only con I have is through-the-body Stringing - I wish D'Addario would design a set labeled specifically for TTB set-ups. Although I have had ZERO problems with these strings and have NEVER replaced a set (I'm of the gunk-is-funk camp), it would be nice to not have to figure out what set will work without doing a bunch of silly measuring, or, worse yet, having to buy another set because you guessed or measured wrong; especially since bass strings can get pricey! Conclusion: It's really simple; if you like a WARM-sounding, foundation bass, get these strings. If you like something a little more ON-TOP of the sound, go with round-wounds.

Good product just takes time to break in
I have been on a search for the perfect bass guitar string. I have these on several of my basses. The tone is good they feel great. They do take awhile to break in. The are “sticky” at first and it takes a bit for that to go away. Not sticky like wet or gummy but my finger does not easily glide across them and release when new. Better as the age.

ECB81M - awesome replacement strings for my Ibanez AEB10E
This is my first foray into flat wound strings. I'd read lots of recommendations on different forums about what strings to put on my acoustic/electric bass, an Ibanez AEB10e (medium (32") scale). A number of folks had these specific strings on this exact model bass, so I decided to give it a try. I'm a relatively new bass player I've been playing extensively for about 7 months, but have played electric guitar, keyboard and many woodwinds over the course of my life. I picked up my AEB10e from a friend who had not been maintaining it. I brought the strings over to a luthier to install and also assess whether other things needed to be adjusted. He popped the strings on and also addressed some bowing/action. While the bass overall plays better, I'm very delighted by the feel of flat wounds vs the much more abrasive "standard" round wounds that come on most basses. Very smooth. While I liked the sound of the old "dull" sound of the ancient strings (reminiscent of an upright!), I've quickly become accustomed to the response and pop to the sound. Next time I need to replace strings on my other basses, I'd definitely look to get an equivalent of the ECB81's in my scale.

Toque suave por uma pequena fábula
As cordas lisas são demais. Gostosas de tocar e muito bacanas para quem procura um som mais aveludado ou grave. Mas nada justifica a pequena fortuna que estão custando, estes tipos de cordas. Comprei em um preço promocional, o que me custou uma corda nova, mas já com dois pontos de oxidação. Esta não é a primeira vez que isso acontece comigo. Como são cordas caras e que têm pouca saída, vale a pena escolher bem o fornecedor.

Bonne qualité la taille est parfaite
J'ai acheté ce jeu de cordes en remplacement des filés ronds sur une Yamaha BB 434 , les cordes ont la longueur parfaite pour ce type de basse avec cordes traversantes. La qualité est au rendez-vous comme toujours chez Daddario. Le son est bien rond et chaud avec évidemment moins de brillance qu'avec des filés ronds ce qui donne un son plus vintage mais lorsque l'on attaque un peu les cordes on retrouve du claquant contrairement à d'autres marques comme Labella qui sonnent résolument vintage et suppriment ce claquant et toute brillance. Le toucher est très agréable et la basse est vraiment très facile à jouer avec ces cordes malgré que la tension soit un peu plus importante qu'avec des filés ronds pour le même tirant. le délais de livraison est rapide. Bref pour ceux qui souhaitent Avoir un son bien rond et chaud dans l'esprit Motown sans se ruiner ces cordes sont parfaites. Le prix peut paraître élevé mais la durée de vie de ces cordes étant également très élevé (plus d'un an en jouant tous les jours avec ) voire infini pour certains, je pense que l'investissement est rentable.
