D'ADDARIO HELICORE VIOLIN STRING SET WOUND E 4/4 Scale Medium Tension
This is the same Helicore medium with one deliberate difference: the E is not bare steel but an aluminium-wound string. That is the whole reason the set carries its own article, H310W 4/4M, and why its total tension differs slightly — 52.5 lb (23.8 kg) against 53.0 lb for the standard H310 in the same gauge. The rest is range standard: a multi-stranded steel core on every string, aluminium on the A, titanium on the D, silver on the G. A wound E feels noticeably softer under the finger and delivers the top register with less bite than a smooth steel wire. Size 4/4 with a 13 in (328 mm) playing length, ball ends throughout.

🏆 SoundsGood — genuine D'Addario strings only, in official packaging.
A Wound E Changes the Contact, Not the Set
A bare steel E is a thin, slick wire: it digs into the fingertip, slides under vibrato and gives the brightest, sharpest top in the set. An aluminium winding makes the string appreciably thicker and less slippery, so the finger holds its place, vibrato on the top string becomes controllable, and the tone matches the character of the other three strings, which are wound as well. For a player with sensitive fingertips, or for anyone who simply dislikes the steel needle up top, that is the reason this set exists.
52.5 lb: The Same Medium With a Different Top
Half a pound against the standard H310 medium is not a gauge change — it is the arithmetic of swapping a bare E for a wound one. Under the left hand the set feels like ordinary medium: dense, but without excess resistance. What changes is the top register: less piercing, better blended with the A, so crossing between the two brings no jump in brightness. Anyone already at home on Helicore medium gets a familiar set with the E corrected to taste.
Two Articles That Are Easy to Confuse
H310 and H310W look nearly identical in a catalogue, but they are different products: H310 carries a plain tin-plated steel E with no winding, H310W an aluminium-wound E. The letter W stands for wound. Everything else — core, lower-string windings, ball ends, 4/4 size and medium gauge — is shared, so the decision comes down to a single question: which E do you want under your finger.

A complete four-string set in official D'Addario packaging marked H310W 4/4M, with an aluminium-wound E. No separate E purchase is needed — the wound top string is already in the box.
Who It's For
A set for the player whose fingertip suffers on a bare steel E and slips under vibrato, for anyone irritated by the sharp, over-bright top of a steel set, and for those already settled on Helicore medium who want the same base with a gentler top string.
Frequently Asked Questions
How does this differ from the standard H310?
Only in the E string: H310 carries a plain tin-plated steel E with no winding, this set an aluminium-wound one. That also shifts the total slightly: 52.5 lb against 53.0 lb.
Why choose a wound E at all?
It is thicker and less slick, so it does not cut into the fingertip or slide under vibrato, and the top sounds less piercing while blending better with the rest of the set, where every string is wound too.
What does the W in the article mean?
W stands for wound. The full article for this set is H310W 4/4M: 4/4 size, medium gauge, wound E.
Is the lower tension noticeable when playing?
Half a pound across the whole set is not a gauge change: under the left hand it feels like ordinary medium. The audible difference is the character of the top string, not the stiffness.
Will these fit a fine tuner?
Yes, every string in the set is ball-ended. Note that a wound E is thicker than a bare steel one, so a tailpiece slot cut for a thin E deserves a careful fit.
Are these genuine D'Addario strings?
Yes. SoundsGood supplies only genuine D'Addario product in official packaging marked with article numbers.
