• Comprehensive Accessory Package: TRN provides a generous selection of ear tips and the included carrying case offers protection for the earphones during transport.
Cons: • Lacks Microphone: The Medusa does not include a microphone.

• Aesthetics (Subjective): While the clear plastic shell with its painted driver is unique, some might find the "eyeball" resemblance less appealing than the intended
The TRN Medusa, the newest addition to TRN's ocean series, takes center stage with its unique design and impressive sound for the price point. Let's delve deeper into its features, sound signature, and overall value proposition.

Design and Build:

While the official inspiration is a jellyfish, the Medusa's clear plastic shell with its intricately painted 12mm dynamic driver undeniably resembles a captivating eyeball. Despite initial online impressions, the Medusa boasts a sleek and cool aesthetic in person. The lightweight build (5.1g per earphone) ensures comfortable wearability during extended listening sessions.



TRN carries over the generous accessory package from the well-received Conch model. This includes:

• Modular Cable: You get all a 2.5mm, 3.5mm, or 4.4mm termination option, offering flexibility for various audio sources. The included Sea Serpent cable (replacing the RedChain of the Conch) features a stylish grey graphene design and is known for its sonic quality, making it a valuable addition on its own.

• Ear Tips: TRN provides a comprehensive selection of tips to ensure a perfect fit and optimal sound isolation. This includes three sets of TRN T-tips, three sets of standard TRN tips, and a pair of memory foam tips, catering to different ear shapes and preferences.

• Carrying Case: A sleek aluminum case protects your Medusa from scratches and dings during transport.


Sound Signature:

The Medusa's true strength lies in its well-tuned 12mm second-generation Diamond-Like Carbon (DLC) dynamic driver. Here's a detailed breakdown of its sonic characteristics:

• Bass: Tight, fast, and punchy, with a focus on midbass presence. The sub-bass delivers satisfying rumble when needed, yet remains controlled and clean, avoiding muddiness in the overall sound.

• Midrange: This is where the Medusa truly shines. The midrange is natural and neutral, with vocals – both male and female – sounding accurate and detailed. The airy and well-extended upper mids ensure clarity without any roll-off, making instruments and vocals stand out.

• Treble: The treble is smooth and neutral, erring on the safe side. It's not overly bright, making it suitable for extended listening without harshness. While not particularly emphasizing sparkle, it handles high volumes well.

Technical Performance:

The TRN Medusa delivers above-average technicalities. It boasts good linear or stereo imaging, with a focus on precise left-right instrument placement. While lacking a fully holographic soundstage, it excels in separation, allowing you to clearly distinguish individual instruments and vocals within the mix.


Overall Impression:

The TRN Medusa offers exceptional value for its price range. Considering the high-quality accessories included and its well-balanced sound signature, it's a fantastic option for audiophiles on a budget or those just starting their foray into the world of high-fidelity audio. The Medusa's versatility allows it to handle a wide range of musical genres with confidence, making it a compelling choice for everyday listening.

Who should consider the TRN Medusa?

• Budget-conscious audiophiles seeking a well-rounded IEM

• Newcomers to the audiophile world looking for a good introduction to high-fidelity sound

• Listeners who enjoy a balanced sound signature with a focus on natural vocal reproduction

• Users who value comfort and portability with the lightweight design
