Converting Wired IEMs to True Wireless: Three Methods

The quest for true wireless convenience with high-quality wired in-ear monitors (IEMs) is a common one. This review explores three popular adapters: the FiiO UTWS5 (2025 edition), the Moondrop Evo, and the Fostex TM2c. Each offers a unique approach to transforming your wired listening experience.

These adapters provide a way to enjoy your premium IEMs wirelessly, bypassing the limitations of many built-in wireless options in budget true wireless earphones. The cost varies significantly, with options available for various budgets and needs.

Moondrop Evo: Budget-Friendly Option

The Moondrop Evo represents a more affordable entry point into the world of true wireless IEM adapters. Priced around $90, it offers a solid performance for its price range, particularly when considering the included ear tips. However, it does have certain limitations.

While the sound quality is decent, the battery life is relatively short (around 4 hours), requiring frequent recharging using the provided charging case. Additionally, the case design is less user-friendly and lacks volume controls; control is limited to play/pause and track skipping.

Fostex TM2c: High-End Performance, Quirky Controls

The Fostex TM2c offers a significant step up in sound quality. These adapters are considerably more expensive but provide high-fidelity audio and come with excellent IEMs. The build quality is top-notch, and the included IEMs are widely praised.

However, the Fostex TM2c's control scheme is unconventional and sometimes frustrating. While it boasts touch controls, its implementation is not always intuitive, and some functionalities are not easy to activate. The volume controls, in particular, are less convenient than expected. Though the controls need refinement, the overall audio performance and IEMs are premium.

FiiO UTWS5 (2025): A Balanced Choice

The FiiO UTWS5 (2025 edition) strikes a balance between price, performance, and usability. This model sits in the middle ground between the budget-friendly Moondrop Evo and the premium Fostex TM2c. The audio quality is excellent, especially considering its price point.

It offers an improved and more user-friendly control system compared to the Fostex TM2c. The touch controls are quite responsive, making for smooth user interaction. This device provides excellent value for its price, and users are likely to find it highly convenient.

A significant advantage is its seamless pairing and connection with devices, ensuring a nearly effortless wireless listening experience.

Conclusion: Choosing the Right Adapter

The choice among these three true wireless adapters hinges on individual priorities. The Moondrop Evo is a budget-friendly option, suitable for users seeking basic wireless functionality without breaking the bank. Although, its short battery life and limited controls are points to consider.

The Fostex TM2c excels in sound quality and includes high-quality IEMs but is more expensive and suffers from less-than-ideal controls. The FiiO UTWS5 stands out as a balanced alternative, providing exceptional audio quality, good control, and a smoother user experience at a more moderate price point.

Ultimately, the best adapter depends on your budget and how much you prioritize convenience versus premium sound quality. Each one offers a different balance of these aspects.
