Hi, Long time head-fier here, but sometime around 2006 I got my hands on Shure E2C IEMs for portable use and AKG K340s for home use, and never looked back. Fast forward 12 years, and now I'm looking back a teensy bit. Mostly, it's because my phone no longer has a headphone jack, and the little dongle they gave me has not been reliable. I've taken to using a little Bluetooth dongle with the E2Cs, but it's kind of a clunky solution - I have to find somewhere to clip it, and uncoil/recoil the E2C cable. I'd rather move to real Bluetooth headphones. I love the sound quality and the isolation of the E2Cs. I tend to use them a lot on airplanes or trains, or riding my indoor cycling trainer with two fans blowing in my face. I do find that they come lose when my ears are a little sweaty, so I'm not opposed to something that is a bit more secure. My preference would be something that has similar sound quality to E2Cs and has similar isolation. I suppose my preference would be to get the type that has two earbuds connected by a flexible cable. I don't want one of those chunky horseshoe shaped things that sits around your neck. True wireless would be fine, but it's not a requirement. I like the idea of being able to take them out and leave them hanging around my neck, and I like only having one thing to charge. Otherwise, I'd like to have the ability to pair them to both my phone and to my TV without having to go through the pairing process again each time I switch sources (Multipoint pairing?). Price range is probably $100-150. So, the new Shure SE215-BT1 is obviously at the top of my list. However, I've been noticing that a lot of the competitors are advertising Active Noise Cancelling and I'm debating if it's worth it. I never really tried it - back in my day of Head-Fi meets, the only headphones with ANC were Bose, and no self-respecting Head-Fier would be caught dead wearing Bose cans. But after a bit of research it sounds like it could be worth a look, especially since the places I use them are fairly steady noises such as fans (which I know is easier for ANC to deal with). If I go on the search for something with ANC, it's a whole different set of IEMs. I've spent a couple hours so far drinking from the fire hose reading reviews, but all the reviews seem to be in one or two camps. They're either reviews from audiophiles who talk mostly about sound quality (Head-Fi), or they are reviews from techies who talk mostly about specs and features and battery life and comfort (other tech sites). I read these articles and it's like "best Bluetooth earbuds under $99" and it tells me which the best one is, but it doesn't tell me if the best one is as good as my Shure E2Cs, or better, or worse. Or I read reviews focused on sound quality, but I'm not really looking for the best sounding IEM for $150, I'm looking for the best overall package. I hope that makes sense. Basically I'm asking for an apples-to-oranges sanity check - does a top ranked ~$100-150 wireless ANC earbud (like Jaybird X3, Jabra Elite Active 65) sounds as good as a 12 year old ~$100 Shure IEM? If it does, I'll happily trawl through all the articles comparing apples to apples and figure out what to buy (although recommendations are appreciated). But I'm worried that those fancy wireless ANC earbuds are basically just $30 cheapo earbuds with a lot of technology bells and whistles strapped to them. I'm also unsure about how the ANC earbuds compare with isolation - the E2Cs have something like 30 dB of isolation from the physical seal around my ear canal. I still get some fan noise through them. But if a fancy ANC earbud only has a couple decibels of isolation due to the physical seal, and makes up for it with ANC to get the same result, I won't bother. I'm only interested in ANC if it does better than the E2Cs.
