Optimal Connections and Fewer Repairs

Cable and socket problems are the most common points of failure for in-ear monitors and earpieces. The patented estron T2™ plug - socket Connector System solves the well-known intermittency issues with a strong mechanical connection which ensures a reliable electrical connection.

Key words are high pull/tensile strength and a high reliability. With a much lower failure rate, the T2 is a well proven alternative to the standard MMCX and 2Pin connector solutions. 

High Durability

Crafted like a talon the plug is grabbed at insertion and after 10,000 insertions still maintains a solid connection.


No Intermittence

High reliability in a miniature design. The system is resilient to intermittence even after heavy use.


Minimal Socket Wear

Focal point of the T2 Connector System is minimum wear on the socket ensuring extended product lifetime.


Stable Pull Force

Made with a dual double leafed spring system to stabilise the variation of pull force. Minimum 3N after 10,000 cycles.


IP-68 Proof

The construction and the silicone gasket combined forms a sealed connector system. IP-68 2 meter water.


Demanding Applications

Tested and approved for the medical industry, the robustness and reliability of the connector system is well documented.


estron T2 Connector System in Action

“The T2 plug-system has brought our products to a new level. Previously, the small models had a fixed cable because all previously available plugs were too large. Only with this small and reliable system was it possible for us to equip all our products with the same plug system. The new DS version brings yet another significant improvement. It is a real pleasure!” –– HEAROS In Ears 

“We prefer the T2 connector system because the number of repairs relating to the T2 interface is nothing compared to other connector systems” –– ONKYO 

“Our design parameters were simple: We needed a cable and socket system that was sweatproof, weatherproof, lightweight, wardrobe-friendly, comfortable, ridiculously strong and capable of high-resolution audio reproduction” –– ULTIMATE EARS 

Designed to Secure Longest Product Lifetime

To endure heavy-duty usage and contribute to prolonged product lifetime, the T2 Connector System is designed for minimum wear on the socket. Crafted like a talon, the T2 Socket DS (Dual Spring) features four robust connection points. Extensive testing demonstrates a solid connection even after 10,000 insertions, showing no intermittence, stable pull force and consistent tactility. 

The estron T2 Connector system is developed based on extensive experience working with ultra-small and high-quality connectors for hearing aids. The T2 was originally designed in 2016 for the medical industry, and since then used in millions of audio applications. 

High durability and reliability in a micro and low-profile design also make the T2 connector ideal for communication in many areas such as broadcast, security, law enforcement, and motor sports. 

The T2™ Connector System is designed and patented by estron a/s. Application note is available upon request.
