Hi All - I'm considering a purchase of Shure SE530 in-ear monitors, and have a few questions for people who have these model earphones or any Shure's in general: For Shure owners: - How's the general experience of ownership been? - Is it necessary to fit the earphones upside down while wrapping them around the ear? (I've seen most people with Shure earphones do this; ideally, I'd like to put them straight in) For Shure SE530 owners: - The IEMs look rather large... do they stick out much? - How's the fit? (e.g. ergonomics, seal; are they generally comfortable?) Also, any advice on the following is greatly appreciated - In order to save some money, I'd like to purchase these from my local Craigslist or eBay; however, I'm a bit skeptical of the authenticity and legitimacy of the item (as seen below): A) Craigslist seller is willing to let them go for $325 (sealed, brand new in box). B) eBay auctions ares going for as little as $276 (that's nearly half-off the list price of $499). Any comments, thoughts and/or concerns are greatly appreciated. Thanks all for the input.
