good product , good colour , good quality

Here's a human review for the Boult Audio Z40 True Wireless Earbuds (Blue):"Boult Audio Z40: A Solid Contender for Everyday Listening (and Gaming!)"I've been using the Boult Audio Z40 True Wireless earbuds for a few weeks now, and I'm genuinely impressed with what they offer, especially considering their price point. As someone who juggles between music, podcasts, calls, and a bit of mobile gaming, these earbuds have become my daily go-to.First off, the sound quality is surprisingly good. The 10mm rich bass drivers deliver a satisfying thump without overpowering the mids and highs. Music sounds full and vibrant, and podcasts are clear and crisp. I'm not an audiophile, but for everyday listening across various genres, I'm very happy.The battery life is a huge selling point. Boult claims 60 hours with the charging case, and while I haven't timed it meticulously, I can confidently say I've gone days without needing to plug in the case. This is fantastic for long commutes or if you just forget to charge them frequently. The Type-C fast charging is also a welcome convenience.

Aweaome product in its range

A fine purchase on my end with reliable battery life , elegant or even stylish look , a decent sound quality and volume levels .I have used these buds as my daily listening device for a long time . This was a rather impulsive purchase as i wanted a earbud for listening to music .As i am not a audiophile i just went with a good looking earbud . But to my surprise these are decent for listening to music and even playing games as they can be used with low latency mode.The sound quality is decent but dont expect a basy sound from the buds they can get very loud and does a good job for paasive noise cancellation.I also liked the battery performance as they can last a really long time i have not been able to kill the buds even while travellingCons :In ear feel of the buds in not great and can get annoying after a couple of hoursThere aren't much but if we nitpick the connectivity has droped on its own a couple of time nothing much if it as it doesn't happen often.The case is not that durable or reassuring as some other buds in the price range.

I have been using it for 9 months long term review!!!

I have been using this since July 2024 and now after 9 months of daily usage due to my work it has totally stopped charging even tho I am charging it through my laptop and mobile not a charger it has still stopped taking charge I tired using a mobile charger but still it didn't take charge. So in my opinion it's good overall the sound and the quality but for long term usage it's bad ..

MINOR SOUND LEAKAGE

It's really a budget friendly product. Thanks to the Boul for it's amazing sound. Alothough I have noticed a problem, there is a minor sound leakage at full volume but don't worry, it's just a minor. If a person is sitting next to you(in a sound of fan) he can't listen what you are listing but if the person is resting his head on your shoulder, then there is a chance that the person can listen what you are listing.
