The Head Sonic Pro is a soft polyester string designed to provide a balanced combination of comfort, control, and durability. Produced by Head, this string aims to deliver the performance benefits of polyester while offering a more forgiving and arm-friendly feel.
Unlike many stiff control-oriented polyester strings, Sonic Pro focuses on playability and ease of use. This makes it a solid option for intermediate players who want the durability of polyester without the harsh feel that often comes with it.

Specs of Head Sonic Pro

Head Sonic Pro Performance
Head Sonic Pro is designed to provide a balanced performance across multiple areas, making it a reliable all-around polyester string for recreational and intermediate players.
Comfort & Feel
Comfort is one of Sonic Pro’s strongest qualities. The softer molecular construction helps reduce vibration and provides a more forgiving feel compared to many firm polyester strings.
While it still has the crisp response typical of polyester, the string bed feels more comfortable during extended play, making it easier on the arm than many competing poly strings.
Power & Control
Power is moderate and works best for players who generate their own pace through their swings. Sonic Pro does not provide explosive power, but it helps control aggressive shots effectively.
Control is solid, allowing players to place their shots with confidence while maintaining a consistent response during rallies.
Spin Potential
Spin potential is average compared to more spin-focused polyester strings. While players can still generate topspin and slice shots effectively, Sonic Pro does not produce the same level of bite as shaped polyester strings.
For players who rely heavily on spin, more aggressive spin-focused strings may be a better option.
Durability & Tension Maintenance
Durability is good for a softer polyester string. Sonic Pro can withstand regular play and training sessions without breaking easily.
However, some players may notice the string losing its crisp feel after extended play, often after several sets, which is common with softer polyester strings.
Pros
- Comfortable feel for a polyester string
- Balanced power and control
- Durable enough for regular play
- Budget-friendly option for club players
Cons
- Average spin potential compared to shaped polys
- Playability may decrease after extended use
Who Should Use Head Sonic Pro?
Head Sonic Pro is best suited for:
- Intermediate and club-level players
- Players looking for a comfortable polyester string
- Players seeking a balanced combination of power and control
- Recreational players who want durability without stiffness
It is not recommended for players looking for maximum spin or those who prefer extremely firm control-oriented polyester strings.
Final Verdict
Overall, Head Sonic Pro is a well-balanced polyester string that offers a good mix of comfort, control, and durability. Its softer feel makes it more forgiving than many traditional poly strings, making it ideal for intermediate players and regular club competitors.
While it may not deliver extreme spin or long-lasting tension stability, Sonic Pro remains a reliable and affordable choice for players looking for an all-around polyester string.
