I am looking for the best audiophile iem a budget of up to 1k USD can get to be used mainly for classical music including chirale works. It will be used with a Headroom DAC/AMP, a little bit old but still great. Important things to consider are: Sound quality: The most possible flat curve. Comfort: As having ears on the small size good fit and comfort for small sized ears is important. It is not important a perfect sound isolatin and as a matter of fact having some ambient awareness is not bad. From what I saw I am thinking at the Sennheisers ie800/800s and the Beyerdynamic Xelento. Any opinion on what would be the best, or any other potential alternative for the use I am planning?
