ADVANCED Model 3 Hi-Res In-Ear Wireless Earphones Bluetooth Headphones AptX AAC Musician IEM with Mic Wireless/Wired Convertible Detachable MMCX Cables (CLEAR)

High quality sound output, and a really beautiful design. I couldn't praise the customer service any more, very helpful and understanding. I have recommended these earphones to my family and friends

Product came with a faulty right earbud. No sound, and after closure inspection it was clear that the right driver had the connector inserted too far. The left was fine, easy to remove and clip back in. The right hand side, after minimal force removed with the connector still inside the right driver.I’m not here to shoot down these IEM’s, not every product comes without a fault and I appreciate that I’m just genuinely unlucky.However, even if they did work, I found that the magnetic connector was just too weak and that was another major issue for me. It seems to disconnect with minimal force.Returned through Amazon’s refund process as of tomorrow.

I have the Bose Soundsports, and they’re brilliant. But, I thought I would try these out, and was disappointed.

The earphones deliver the quality sound I was expecting at this price point. Perhaps seasoned audiophiles who spend thousands on gear might find a fault, but personally I have been impressed and pleased with the way the earphones sound after hundreds of hours of use.The product also looks great (especially in clear with green earbuds) and is quite light/easy to wear around your neck for long periods of time. The supplied earbuds are quite comfortable and hold up well over long periods of time, although if you're more fussy than most people about fit/comfort you might invest in some moulded ear tips instead.The connection range is good and I have no doubts it is up to and perhaps slightly beyond the advertised distance. However, the connection has on a rare occasion been crackly and spotty for no particular reason. Even when sat right next to the device the audio is streaming from it can sometimes go crackly and have a dodgy connection. This is quite frustrating as it usually requires disconnecting and reconnecting. You can of course go for a wired connection, but this defeats the purpose of paying a premium for bluetooth headphones. I would say that the ear monitors themselves are actually too hard to remove from the wires. They are quite small and rubberised at the connecting point, and are therefore really hard to grip. I have struggled to remove them for several minutes before. You have to pull so hard it feels like you are going to break them and so i avoided using the wired connection for months until I was eventually brave enough to just yank hard on them.The battery life is decent for its class, and I would say lives up to the ~ 5 hours advertised. The earphones charge fairly fast and hold their charge quite well if unused. The supplied wires and miscellaneous items are of good quality.The left ear monitor on my pair actually died after about a year's worth of use which was disappointing. Although, I emailed ADVANCED sound and they replaced the faulty left monitor (and gave me another right monitor too!) at no cost. Seeing as I live in the UK and am not really qualified under the US warranty I was very pleased by this and so I would recommend the company as one with good character.All in all I think I got what I paid for. Pretty darn good earphones at a pretty darn good price. 4/5 would probably buy more of these if/when my current set pack it in.
