Sony ULT WEAR 900N Wireless Noise Canceling Headphones - Renewed

In this review of the Sony ULT WEAR 900N (Renewed) the bottom line is simple: these over-ear headphones are for listeners who want deep, impactful bass and serious noise reduction without paying full retail for new gear. The Certified Refurbished condition means you get a manufacturer-refurbished unit with limited or no wear and all original accessories plus a 90-day limited hardware warranty, making it an attractive value for buyers who prioritize sound and noise canceling over fresh-box aesthetics.

Key Features

• ULT bass modes: Press the ULT button to switch between powerful low-frequency ULT1 and even deeper ULT2 settings so bass-forward tracks feel more physical and present.
• Advanced noise canceling: Dual noise sensor technology paired with the V1 processor reduces ambient noise so vocals and instruments stay clear in busy environments.
• 360 Reality Audio and EQ: Personalized EQ and 360 Reality Audio help place you in the center of the mix and tailor tonal balance to your tastes.
• Comfortable fit: Smooth cushions mold to your ears for longer listening sessions without discomfort.
• Portable design: A swivel fold mechanism and compact carry case make these headphones easy to pack and transport.
• Certified refurbished value: Manufacturer refurbished condition includes original accessories and a 90-day limited hardware warranty for added peace of mind.

Who It's For

These headphones suit listeners who favor rich low end and immersive, canceling performance - commuters, frequent flyers, and bass lovers will appreciate the ULT bass modes and V1 processor noise suppression. The foldable design and included case also make it a good choice for people who travel with their gear.

Shoppers who need brand-new-box cosmetics or a long manufacturer warranty should look elsewhere; similarly, those seeking a neutral, studio-flat response may find the emphasis on ULT bass and immersive audio less ideal than a reference headphone.

Pros & Cons

Pros

Cons

• Refurbished condition means some units may show limited wear, and shoppers wanting pristine packaging may prefer a new unit.
