Design and Build Quality

The Sony MDR-XB55AP showcases a sleek and modern design, typical of Sony’s aesthetic standards. The earbuds are lightweight and crafted to fit comfortably in the ear canal. They come with four sizes of hybrid silicone ear tips (SS, S, M, L) to ensure a secure and personalized fit for various ear sizes.

The cable is a tangle-free, serrated design which enhances durability and convenience. It’s made from Litz wire which helps in reducing signal loss and enhancing audio performance. The gold-plated L-shaped plug is sturdy and designed to withstand regular use without easily succumbing to wear and tear.

Sound Quality


The standout feature of the Sony MDR-XB55AP is its Extra Bass technology. With a frequency response that goes as low as 4 Hz, these earphones are capable of delivering deep, powerful bass that is both clear and impactful. This makes them ideal for genres such as EDM, hip-hop, and pop, where bass lines play a significant role in the music experience.

Mids and Highs

While the primary focus is on bass, the MDR-XB55AP doesn’t completely neglect the mids and highs. Vocals and instruments are clear and present, though they might take a backseat compared to the pronounced bass. The high frequencies are crisp and detailed, but without the harshness that can sometimes plague budget earphones.


The soundstage is moderately wide for an in-ear model, providing a sense of spatial awareness that enhances the listening experience, particularly for live recordings and classical music.

Comfort and Fit

Comfort is crucial for in-ear headphones, and the Sony MDR-XB55AP delivers in this aspect. The lightweight design and variety of ear tips ensure a comfortable fit, even during extended listening sessions. The earphones stay in place reasonably well, making them suitable for use during light physical activities like walking or commuting.

Microphone and Remote

The inline remote and microphone are convenient for users who frequently make calls or use voice commands. The single-button remote can be used to play/pause music, skip tracks, and answer/end calls. The microphone quality is decent, offering clear voice transmission for calls, though it may pick up some background noise in louder environments.

Noise Isolation

While the MDR-XB55AP doesn’t offer active noise cancellation, its design and snug fit provide effective passive noise isolation. The silicone earbuds create a seal in your ear canal, blocking out a significant amount of ambient noise. This feature is particularly beneficial for commuters and travelers who want to enjoy their music without interruption.


The build quality of the MDR-XB55AP is solid. The tangle-free cable, combined with the robust L-shaped plug, contributes to the overall durability of the earphones. They are built to handle everyday use, making them a reliable choice for daily commuters and casual listeners.

Price and Value

Priced competitively, the Sony MDR-XB55AP offers excellent value for money. It’s an attractive option for those seeking high-quality sound and durable design without breaking the bank. The additional sizes of earbuds and the inclusion of a carrying pouch add to its overall value proposition.
