I've had these for 3weeks now and they are very loud pair of ear buds and nice feel and touch to the earbuds and case. Bluetooth Connection is fast enough and battery life is pretty decent. However there is slight bass distortion when U turn it up beyond 75% but good treble and mid sound quality. For this price I can't complain too much. 🤓

I’ve been using the Boult Audio K40 True Wireless Earbuds for a few days now, and I have to say, they’ve really exceeded my expectations! These earbuds are incredibly versatile, making them perfect for a variety of uses, whether it’s for listening to music, taking calls, or even gaming. The 48-hour playtime is definitely a standout feature. I don’t have to worry about charging them constantly, which is so convenient, especially on long days when I need them for work or just unwinding with some music. The Type-C fast charging is a nice touch, allowing for quick juice-ups when needed. The sound quality is crisp, and the 13mm bass drivers deliver a surprisingly deep and punchy sound. Whether I’m jamming to my favorite playlist or watching videos, the audio is clear and immersive. I also really appreciate the Clear Calling feature, with 4 mics ensuring that my voice is loud and clear during calls. Even in a noisy environment, I haven’t had any issues with the quality of my calls, which is a huge plus for both work and personal use. As someone who enjoys gaming, the 45ms low latency gaming feature is a game-changer! There’s no lag, and I get to enjoy a seamless gaming experience without the usual delay that many Bluetooth earbuds have. Finally, the ergonomic design with a premium grip ensures that the earbuds stay snug in my ears, no matter what I’m doing. They’re so comfortable, I can wear them for hours without discomfort. All in all, these Boult Audio K40 Earbuds are a fantastic option for anyone looking for high-quality, all-around wireless earbuds. They’re great for daily use, whether you’re working, exercising, gaming, or just chilling out with your favorite tunes. Thanks to Amazon for bringing this amazing earbuds to us!

For the price, these earbuds have amazing sound. The sound they produce is comparable to that produced by earbuds that are hundreds of pounds more expensive. I tried a number of the earbud models from this Indian manufacturer, and there wasn’t one pair I wasn’t impressed with. Seriously, they cost about a tenner, you have no decent excuse for not trying them out yourself. Two thumbs up, for the entire range! 👍🏼👍🏼
