Koss BT115i Wireless Bluetooth In-Ear Buds with 18+ Hour Battery

I charged these once and used them all week for workouts and calls. The battery life is truly 18+ hours. They connect easily and sound great.

At $15, these are a steal. They sound good, have a decent mic, and the battery lasts forever. The only issue is the fit – they can be a bit loose if you have small ears.

I use these for work calls all day. The mic picks up my voice clearly, and the battery lasts through my entire shift. They're comfortable enough for long periods.

They're okay. Sound is fine, but they don't isolate noise well. The controls are a little finicky, too. But for the price, they're acceptable.

I've had expensive earbuds that don't last as long. These are comfortable, sound great, and the battery is amazing. I've already recommended them to my friends.

These stay in my ears during workouts and the bluetooth connection is solid. Battery life is great. Only downside is they don't come with different ear tips.

They kept falling out of my ears. The sound quality is okay, but I couldn't get a good fit. I ended up returning them.

I couldn't believe the price for these. They sound like earbuds twice the cost. The battery is fantastic. This is my second pair of Koss and they never disappoint.

Very good earbuds. Sound is clear, battery is long. Only reason I don't give 5 stars is the lack of a case – they're so light I'm afraid of losing them.
