Review: I totally recommend them for those looking for reliable hearing aids - I am very satisfied with these hearing aids. The sound quality is clear and well balanced, with good bass and defined treble, ideal for both music and calls. The necklace-type design is very comfortable, they do not move when using them and are perfect for daily use, even for several hours in a row. The materials feel resistant and of good quality, and the headphones fit the ear very well. The connection is stable and the battery offers long-lasting performance, perfectly fulfilling what was promised.
Review: Pleasant surprise, hidden gem! - Long story short, I was in the market for earbuds. I use them daily, all day, during work, on a construction site. About every 2 years or so I have to replace pairs I've previously purchased and it was time. I was interested in getting neckband style buds after some colleagues showed me how practical they are for a job site. It's honestly quite difficult to find good neckband style buds these days and pickings are slim. I hunted around for a while and decided to try these after not being able to find really any negative reviews outside of the occasional "they stopped working," comments that are typical for electronics - and even those comments said customer service was happy to help them. I looked up the brand and their other products, all seemingly decent reviews... They seemed like they were a simple design, very practical and checked the boxes - great battery life, simple to use buttons, decent call quality, and people said they sounded good too. I was skeptical because how are people raving about these things when they only cost 50 bucks?! I can honestly say after using them that these are a gem. They are cheap, and what you get definitely hits higher than it's price bracket. The sound objectively is a pretty standard profile that pushes bass and treble a little, but without losing anything in the mids - and I love it! That 13mm driver does work, and these things are WAY TOO LOUD. What surprised me though was the clarity in the music, because I thought that I would settle for below average sound with a very flat profile... But I was very wrong. It is crisp and clear, louder than I can handle and the profile they set has a nice balance too it - but if you like a flatter sound then you probably won't enjoy it as much as I do. Lastly, the battery is truly a full work week (or two) kind of battery. I went through an entire day and it still reads 100 percent. And even with that nice big neckband, it's light and comfortable, and it feels premium. I can't speak to longevity, I have only had them for a few days, but as long as they last a couple years - pretty standard for most electronics - then I will be happy with them, and hopefully if I run into trouble I can lean on customer support, which other reviews say is pretty good. All in all, I don't think I could hunt down a better product for the money right now - major kudos, cuz I am picky as hell and love to watch reviews and shop around, but this was worth the buy. Good luck people 🥂
