Bose QuietComfort 45 Wireless Noise Cancelling Headphones – Triple Black (Renewed)

Meet the Bose QuietComfort 45 wireless headphones, renewed for value without compromising performance. Each unit from the Amazon Renewed program is pre-owned or refurbished, professionally inspected and tested to look and work like new. If you’re not fully satisfied, Renewed products are eligible for replacement or refund under the Renewed Guarantee, adding confidence to your purchase.

Calm, comfortable listening with versatile sound

Quiet, comfortable, and immersive sound define the QC45. Bose uses a network of tiny mics to measure ambient noise, then counter it with precise opposite signals. The result is a listening environment you control, whether you’re commuting, working, or winding down at home.

The TriPort acoustic architecture adds depth and fullness to your music, while volume-optimized Active EQ keeps a balanced feel at any listening level. Bass remains present when you lower the volume and clarity stays sharp at higher levels, so your audio feels consistent across tasks.

Keep it personal with adaptive sound

Personalize your audio with adjustable EQ. Tailor bass, mids, and treble to your taste, or choose from presets for different genres or moods. Quiet Mode delivers maximum isolation, while Aware Mode lets you stay connected to your surroundings while listening.

Built for long days and on-the-go versatility

• Up to 24 hours of battery life on a single charge for extended use away from a power source.
• A quick 15-minute charge provides about 3 extra hours, keeping you moving when time is tight.
• Wired listening is available by plugging in the included audio cable for longer sessions or to preserve battery life.

Renewed confidence, clear expectations

These headphones come with the assurance of the Amazon Renewed program. Each unit is inspected and tested to ensure it looks and works like new, with any necessary parts refreshed. The Renewed Guarantee offers a path to replacement or refund if your experience doesn’t meet your expectations.

Who it’s for

If you value a quiet, comfortable fit with flexible sound control, the QC45 can adapt to your daily routine. They are well-suited for travelers seeking a calm cabin feel, remote workers pursuing focused listening, or casual listeners who appreciate a balanced, natural sound profile.
