For weeks, the EP103 (Model Number: 30637) 3.5mm wired earphones have been my daily drivers. I’ve used them extensively with my MacBook Pro 2021, iPhone, and even my PS5, putting them through the paces to deliver a thorough and honest review.

The EP103 boasts a number of features, as advertised. The claim of noise isolation is a key selling point, and I’ll discuss how well it performs in the performance section. The multi-function button is a welcome addition, allowing for easy call management and music playback control. The inclusion of multiple ear tip sizes is also a plus, ensuring a comfortable and secure fit for various ear shapes and sizes. The design is simple and unobtrusive, which I appreciate.

Sound quality is surprisingly good for the price point. The bass is definitely present, although not overpowering. The mids and highs are clear and well-balanced, though I did notice a slight lack of detail in complex musical passages at higher volumes. The noise isolation, while not perfect, is effective enough to noticeably reduce background noise on commutes or in busy offices. The microphone performed admirably during calls; my voice came through clearly and I experienced minimal background noise interference. I did find the cable slightly prone to tangling, a common issue with wired earphones.

I tested the EP103 extensively across various devices, and the compatibility was flawless. They worked seamlessly with my MacBook Pro, iPhone, and PS5, offering consistent performance across the board. Durability seems decent so far; they have withstood daily use without any significant wear and tear.

Pros

• Good sound quality for the price

Cons

Overall, the EP103 (Model Number: 30637) offers excellent value for money. While it’s not perfect, its strengths outweigh its weaknesses. The combination of good sound quality, effective noise isolation, convenient controls, and wide compatibility makes it a strong contender in the budget-friendly wired earphone market. I would comfortably recommend these to anyone looking for a reliable pair of earphones for everyday use.
