These IEMs are amazing. If you're on a $100 budget to get the best possible sound, this is your best bet. I've tried Final Audio Design (Heaven II, E3000, E2000), 1More (Triple, Quad) and Periodic Audio (Mg) IEM and overall it breaks all other options (I'd elaborate, but just head to headfi for detailed reviews ). It's also very, very durable. If you're a fan of Justin Bieber, One Direction or Britney Spears, don't even try to buy anything over $30. My guess is that since you're looking at the Alpha&Delta you've done your research and want exceptional sound quality. That's the closest you can get in this price range. Don't be fooled by the comments of those who are blown away by the sound quality that 1More Triple Driver offers. That just leaves the models I listed above in the dust. The only two models to choose from besides this one in this price range are the DN-1000 and the VSonic GR07 (Classic or Bass, it really depends on your preference). I chose this one because it's much stronger. If durability isn't an issue for you, these will be incredible for you. lots of bass hits. You'll fall asleep with them in your ears and refuse to take them out to hear more. If you're on a budget, just do it. There's no competition when everything is considered, from sound quality to durability.
