D’Addario H510 Helicore Cello String Set, 4/4 Scale Medium Tension (1 Set)– Stranded Steel Core for Optimum Playability and Clear, Warm Tone – Versatile and Durable – Sealed Pouch Prevents Corrosion

I'm a violin teacher of a lot of young students. Violinists have strong preferences for their strings, but this brand seems to work well for most student instruments. It's got a nice robust sound, with a nice warm-bright balance. I use a different string for my personal instrument, and recommend other strings for more advanced students, but this is my go-to for younger students for quality and affordability.

I bought a set of D'Addario Helicore Cello Strings for a recently purchased second cello (which was used). The cello, from a reputable company, came with terrible sounding strings which needed immediate replacements. Since I wanted to compare my two cellos by equalizing the strings and using the same bow, it made sense to order Helicore strings (FYI my primary cello came with the Helicore). As stated in other reviews for this product, the strings made a huge improvement in tone and projection on my second cello. The "o.k." cello became a decent one simply by changing the strings. I was amazed to find that the Helicore strings made that much difference. Now, I'm really sold on the Helicore strings. I believe it's worth spending $100 on this set. I highly recommend it.Perhaps, you may be wondering how the comparison of the cellos went. My primary cello (newer but better material) easily won, but my second cello is not too far behind now.Update (9/15/2013): Since my earlier post above, I've purchased third cello, and as in the past, I've ordered a new set of Helicore and replaced the strings that came with the cello. I, of course, played the cello with the original strings first, but they were not good enough for me. The new set of Helicore made amazing difference once again. The Helicore strings on the first and second cellos are still performing wonderfully. I love Helicore, but I am planning to test out a different set of strings next time. I will write a review, comparing the set with Hlicore. Until then, happy celling!

Put these on a cello I just bought in the 3k range. The existing A string broke from age, so I decided to go all in with a new set. These strings were selected for my celllo by the original maker, and oh my do they sound incredible! The sound is not exactly “bright” but has the fullness and richness to bring out that extra dimension of sound from the instrument body itself.Only downside, they might exaggerate your wolf tone. Because the harmonics are so rich (and there’s just plain more sound coming out of the instrument) , you may find that your wolf has moved, or split. I’m waiting for a wolf tuner I ordered to arrive, to see how it balances these.They also break in very quickly, only had them on for a couple days, and the tuning was very stable. Was surprised to come back the 3rd day and find my D and A strings still in tune.

I upgraded from a student cello to an Eastman MC-405. My teacher recommended getting something better than student grade strings for it, so I decided to give the Helicores a try. The C, G, and D string are great! They have a nice tone and are easy to play, the A string, however.... the A string is has a very harsh, tinny, metallic sound to it. I brought this up on a Facebook cello group, and it turns out that this is a very common opinion. No less than a dozen people recommended getting a Larsen A string to go with a Helicore C G and D. That seems to have fixed the problem! I am still loving the CG and D strings though!

Helicore are great for C and G. I don’t like them as much for d and a.I really like Helicore C and G combined with Larsen d and a.I like that the Helicores are thin and fast response for C and G. I like the tone too. On d and a they seem too thin and too bright. They’re also more affordable than other C and G strings and I don’t think they’re any less nice than more expensive C and G strings. Durability is good too.

I use these on my Yamaha SVC-110 and my acoustic cello. They sound great and don't break the bank.

Helicore is a durable, reliable string to use. You can buy them on Amazon for slightly less than music stores. Just watch who you buy them from. My first delivery was an empty bag that wasn't sealed. Thankfully Amazon was able to ship another one out (free of charge). The only significant issue being we had to wait and could not use the cello until the strings arrived.The Helicore string set is a great value for money. It did not take long to install and after initial adjustments only needs the occasional fine tuning.

A great value with a nice woody texture. Nice neutral sound. Good for chamber music or orchestra.
