I bought these to replace my LG hbs-1100 Tone Platinums that failed ..(twice). I used them daily, and as an IT professional, having a wireless set of heaphones with a microphone is critical for when I'm working in tight spots, cramped server rooms, etc.
I have to say these are an incredible upgrade.
-Easy and quick to pair using either regular bluetooth pairing or NFC pairing
-Absolutely wonderful sounding, balanced sound. clear, punchy lows, exceptional mids, and brilliant highs. These really surprised me. Some of the best in-ears I have ever heard. With some EQ help, these are definitely the best in-ears I've used.
-Great microphone. Does an excellent job picking up my voice when I'm on the phone (I use this feature a LOT at work)
-extremely comfortable to wear, in cool dry climates. The leather feels great and doesn't pull your hairs like some other similar sets do.
-Build quality is exceptional! Thicker cables than competitors, Metal housing for the earbuds, leather around the neckband, tactile buttons, great feeling plastics. They also come with many different sizes of rubber ear inserts for a wide variety of ear sizes, that are definitely higher quality than competitors. Comes with a fantastic hard-shell carrying case to protect them when they're not in use, which is a huge plus, especially for those that travel.
-Battery life, so far, has been solid. Been 3 days without a charge so far with fairly heavy use. Packaging indicated 10 hours of batter life, but it seems like I've gotten more out of it already.
-No magnets or other place to put the earbuds when you're not using them actively. They just dangle there. This is only a con because of convenience. I can definitely see why they took this approach, since it allowed for a higher quality cable and construction of the unit overall.
-The leather around the neckband could get funky or even frayed over time.. especially in warmer climates, where you might sweat. The manual specifically advises against using any sort of leather protectant on it (because it's in contact with your skin), and you should try to avoid getting them wet. If you do get them sweaty, just wipe them off with a slightly damp cloth, then dry immediately. This also means these wouldn't be good for the gym or running.
Overall, these are great headphones for anyone who travels, or works out in the field. Especially for IT professionals who need to be on the phone frequently.
