Melomania M100 is my first Cambridge Audio product. Their buds aren't among most popular ones in community, so my expectations weren't high. The case is chunky and cumbersome, buds design is on weird side (if you look from the front), but for me they are extremely comfortable and have dead stable fit (office work, walking outside, home duties). Controls cannot be remapped, only disabled individually, and it takes some time to get used to unusual buds shape (the trick is to tap them with thumb rather than index finger). Soundwise I was afraid of getting a very bright sound, but they deliver quite some lower frequencies and overall balanced sound that I appreciate much. Though I'm happy with default tuning, one can EQ them or use one of presents, which are by the way well crafted and all makes sense. They have Snapdragon Sound on-board, so audiophiles can enjoy aptX Lossless heaven, but I found it working well only when I was at the desk, any kind of movement around the table and I was getting dropouts, i.e. it doesn't fall back to aptX Adaptive smoothly. That was the case with both smartphone (Xperia 1 VI) and FlooGoo FMA120 USB dongle. Luckily the latter one allows me to opt-out aptX Lossless, so I could enjoy very reliable aptX Adaptive, unfortunately that's not an option for smartphone because Melomania app don't give me such an option and the only way is to manually switch to aptX via Android Developer Menu. Speaking of the dongles, unfortunately M100 has poor to none compatibility with all popular hi-res dongles, e.g. Creative BT-W5, Sennheiser BTD600, or aforementioned FlooGoo FMA120. Don't get me wrong, they are great for music consumption (when not aptX Lossless in use of course), but for calls I got either no (barely audible) or very-very-very bad recording quality. And shortly about the usual points: fantastic battery, surprisingly strong ANC, mediocre transparency. As you can see these aren't ideal at all, but who's ideal these days? I tried quite some other buds, e.g. Momentum 4 TWS, Elite 10, LG T90S, Live 2 Pro, etc. Believe me, every single one of them has their flaws if you're looking for an all-rounder. But all in all, though I didn't expect that initially, I love these buds.

Ok for the money. Still getting use to them as a different fit to my Apple AirPods . Sound good so all in all I’m happy with them. Wish I could pair with my Evo CD player as have some discs that can’t been streamed.

Great customisable sound, really comfortable in ears, they sound really good. Would have liked to have had a pair of medium memory foam tips as these seemed better for noise cancelling but they only come with small and large, which don’t really fit my ears so I have to use the silicone tips which are good but not so good for noise cancelling. Love the Melomania app where you can do a lot of customisation to your buds. The case and buds feel really good quality, I would definitely recommend.

I'm very happy with the purchase. The ANC isn't quite on par with the Bose QC Ultras (full ANC seems a little stronger with the Bose and the "aware" mode on the Bose seems clearer than the "transparent" mode on the M100s) but the difference between the three modes on the M100s also seems more noticeable, they sound great and the ridiculously-longer battery life more than makes up the difference (a single charge of the M100s is near-equivalent to a complete charge of the QC Ultras + the charging case; it's not even a competition in that regard). I also dig the style of the M100s; they fit pretty securely and I don't feel them or bump my fingers against them quite as much as the last earbuds. This is my favorite Bluetooth headset yet.

I'm a 40 yo misanthrope living in an apartment in the Divided States of Embarrassment, so I wear my headset nearly any time I'm conscious. I just did a web search for headsets with long battery life. The specs on the website looked solid, I made the purchase and I'm as satisfied as one such as myself can be.
