Strengths & Weaknesses

Strengths:

• Excellent feature set for the price: ANC, long battery life, app control, multi-point Bluetooth.

• Good overall sound quality: According to reviewers the tuning is “generally balanced” and the app gives extra flexibility

• Comfortable and portable: Lightweight and foldable, good for commuting and travel.

• Wired option: If battery runs out or you prefer a wired connection, you’re covered.

Weaknesses:

• Ear-cup size & comfort: Some testers noted that the ear-cups are on the smaller side and might feel tight if you have larger ears or wear glasses

• Noise cancellation performance: While ANC is present and helpful, it may not be as effective at blocking very low-frequency noise (such as bus engines or airplane cabin rumble) as some higher-end models

• Build quality: Some comments point out the plastic build feels somewhat budget-oriented

Design & Usage Impressions

In Blue/Black colorway, the Tune 770NC look sleek and modern, with subtle branding and a clean finish. They fold flat which makes them travel-friendly and the padded ear-cups and headband enhance comfort. The ability to switch between ANC, TalkThru, and Ambient modes means you can tailor them to an office, commute or casual listening environment. They’re particularly well-suited to everyday use: listening to music, watching videos, doing productivity tasks, or simply relaxing.

Some users on Reddit commented:

“the tune for my preference did way better … they felt comfier while the live was putting pressure on my head ‘cuz of my glasses.” Reddit

So if you wear glasses or need comfortable all-day wear, that’s an encouraging note.
