SennheiserPRO IE 100 PRO WIRELESS CLEAR In Ear Dynamic Monitoring Headphones

Only just got these as a present from my wife from Amazon. Am tempted to send them back but am hoping with some burn in they will change.Not sure I have much positive to say other than they are clear, so negatives:- Tinny, base is almost none existent (Sennheiser I have found can start like this and get better over time).- soundstage feels compressed, might be down to a lack of low end, at the moment they sound like listening to cheep hifi in the corner of the room while I'm a few meters away. Sonically they are like b&w's rock solid htm2s I owned in my teens with a low end cd player and a Sony surround sound amp).- they feel cheep, but might be down to them trying to save weight, I am glad I have the warentee with them I don't see them lasting.- the cord is too short by at least 2 inches/5cm to 4 inches/10cm. It's so short it wouldn't allow them to sit on my neck with one headphone in. Instead the other headphone sits about where it should but is pulled tight across the back of my neck. This is because there isn't enough cable for them to rest on my sholders, I can feel this and it might become annoying.- I've been listening to them while writing this and am already finding their bright treble annoying. Ime to leave them playing on there own somewhere for 12 hours and see if some use helps.So people have an idea of my previous experience with headphones, I have a pair of Sennheiser hd600 ovations that are now 25 years old and which I love. I've had 10+ pairs for senhiser in ear headphones before. These were the i series I think they were i3 (at least 4 sets) and i5's (2 sets) both of which suffered with being bright to start and just as they got good the cables would de-laminate. Prior to that it was Sennheiser cx series I believe. I also have had Sennheiser hd595's, hd565's, 400's, Bose quiet connect 1's and then 2's, Sony xb400, the wrap around ones from the late 90's (can't remember the model), several sound magic headphones and I'm sure some over my time I can't remember. I do actually like Sennheiser but do feel these aren't up to their standards yet.I will report back after some but in and actual use, or if they really are no good and my wife doesn't kill me for wanting to return her kind gift.I will say if you want something out of the box that sounds great and which I have given a very hard life for 2 years the Bose qc2's are much better than these even if the control system is annoying (if you have to push one in for a better fit it will screw up your music/video/audiobook!
