Description
The Head Sonic Pro 16L is a premium co-polyester tennis string designed for intermediate and advanced club players who demand the perfect balance of comfort, power, and control. Cut fresh from the reel to 12 meters, this string delivers a softer, more arm-friendly response than traditional polyester strings while maintaining the durability and spin potential that competitive players need.
What makes Head Sonic Pro 16L stand out is its unique soft molecular construction. HEAD engineered this co-poly tennis string with special additives that create a plush feel at contact without sacrificing the crisp response players expect from a quality monofilament. For players across India looking to upgrade their string setup, this is an excellent choice that performs in all conditions.
WHY HEAD SONIC PRO 16L IS THE IDEAL CHOICE FOR CLUB PLAYERS
HEAD has been at the forefront of tennis innovation for decades, and the Sonic Pro series represents their commitment to creating accessible, high-performance strings for serious recreational players.
Soft Co-Polyester Construction
Unlike harsh, boardy polyester strings that punish your arm, the Head Sonic Pro 16L features a refined co-polymer formulation that provides exceptional comfort. The soft molecular construction allows the string bed to pocket the ball effectively, giving players a connected feel on every shot. This HEAD Sonic Pro String is particularly beneficial for players who practice frequently and need a string that won’t cause fatigue or discomfort during extended sessions.
16L Gauge for Optimal Balance
The 16L gauge (1.28mm) sits perfectly between the durability of 16g and the feel of 17g. This middle-ground thickness gives players enhanced spin potential while maintaining solid tension retention. The Head Sonic Pro 16L offers enough bite to shape shots effectively, yet provides sufficient mass to deliver controlled power on flat strokes and volleys.
PERFORMANCE CHARACTERISTICS
Understanding how this HEAD Sonic Pro Tennis String performs helps players make confident decisions about their setup.
Power and Pop
Despite being a control-oriented string, the Head Sonic Pro 16L delivers surprising pop off the string bed. Players report a lively response that adds depth to groundstrokes without feeling uncontrollable. The soft polyester string construction creates a trampoline effect that helps generate pace, making it easier to hit through the court against defensive opponents. This makes the HEAD Sonic Pro String ideal for all-court players who need versatility.
Control and Precision
The primary strength of this co-poly tennis string lies in its predictable response. Full swings result in shots that land where intended, with the string providing excellent directional control. Players can take aggressive cuts at the ball with confidence, knowing the Head Sonic Pro 16L will help keep shots inside the lines. The consistent feedback allows for precise shot-making in pressure situations.
Spin Generation
While not a shaped or textured string, the Head Sonic Pro 16L still offers respectable spin potential. The smooth surface slides efficiently, creating good snapback for topspin groundstrokes and kick serves. For players who don’t need extreme spin but want reliable ball rotation, this comfortable poly string delivers exactly what’s needed. The spin complements the control characteristics beautifully.
Arm-Friendly Comfort
One of the biggest selling points of the HEAD Sonic Pro Tennis String is its arm-friendly tennis string properties. The soft molecular construction significantly reduces shock transmission compared to stiffer polyester alternatives. Players with sensitive elbows or those recovering from arm injuries will appreciate the gentler feel. You can string at higher tensions without the harsh feedback that typically accompanies firm poly strings.

STRINGING RECOMMENDATIONS FOR INDIAN CONDITIONS
Hot and humid conditions across India affect string performance. Here’s how to optimize your HEAD tennis string India setup.
Recommended Tension Range
For most players, stringing between 50-56 lbs provides optimal performance. In hot conditions common in Chennai, Mumbai, Delhi, Bangalore, and Kolkata, strings play looser, so starting slightly higher helps maintain consistent feel.
- For maximum power and comfort: 48-52 lbs
- For balanced performance: 52-54 lbs
- For more control: 54-58 lbs
Hybrid Setup Options
The Head Sonic Pro 16L works excellently in hybrid configurations. Use it in the mains with a softer synthetic gut or multifilament cross for enhanced comfort. Alternatively, pair it with natural gut mains for a premium setup that maximizes feel while maintaining durability in the crosses.
COMPARING WITH OTHER HEAD STRINGS
Understanding where Sonic Pro fits in the HEAD lineup helps players choose wisely.
The Head Sonic Pro 16L sits between the firmer HEAD Hawk and the softer HEAD Lynx in terms of stiffness and power. Compared to Sonic Pro Edge, this round version offers a more muted, controlled response without the aggressive bite of the shaped variant. For players who found Hawk too stiff but need more control than Lynx provides, this HEAD Sonic Pro String hits the sweet spot perfectly.
