Looking for a reliable pair of neckband headphones that won't break the bank? The Sony WI-C400 might be just what you need. These headphones offer a decent balance of sound quality, comfort, and battery life.
Pros:
Long-lasting battery: With up to 20 hours of playtime on a single charge, you can enjoy your music for days without worrying about running out of juice.
Comfortable fit: The neckband design is lightweight and doesn't feel too intrusive. The earbuds come with multiple ear tip sizes to ensure a snug fit.
Good sound quality: While not audiophile-grade, the sound is clear and balanced. The bass is decent, but it won't blow you away.
Simple controls: The buttons are easy to find and use, even when you're on the go.
Cons:
Average build quality: The plastics used feel a bit cheap, and the neckband might not be as durable as some other options.
No noise cancellation: If you're looking for headphones to block out background noise, these won't be ideal.
Limited features: There aren't any fancy features like wireless charging or active noise cancellation.
