Help with EarPods.

Well, as usual “high end” is relative in all things audio.  For me, if I want true high-end earbuds for classical I want excellent soundstage capabilities, and for this I’d look to more elaborate, multi-driver wired designs.  In the $1500 range I’d point toward the ThieAudio Prestige LTD or the FiiO FX17 as some solid choices.  They’re above my budget, but in the sub-$500 level and as an example my FiiO FH5s, which uses two dynamic drivers for the bass and mids and dual balanced armatures for the treble, sound considerably more open and three dimensional than my single-driver TinHiFi T5 that, while still decent, sound relatively more congested and squashed (I believe the B&Ws you heard also use a single driver).  As always, it all depends on how deep you wanna dive in but suffice it to say there’s a lot more to be had performance wise as you up your budget.  Hope this helps, and best of luck.

Thanks for the recommendations,  Very enlightening.

You’re so right.  High end is so relative, especially with ear phones.  
When I said the sound of the B&W was “wonderful,” I meant relative to earphones I have heard.  
 I was looking for a wireless, so your recommendation won’t work with me

One of the founding assumptions of high fidelity audio is that it is in a quiet space. It is great if you have a location with an ambient noise level is in the 20’s db. It profoundly makes a difference. Most of the time, it is probably likely most folks have listening areas in the 30s db. If you are into the 40s... it is a compromised area and you are just not going to be listening to high end sound because of the high noise floor covering details and nuance... and filling in the silence in between notes or sounds. For a reference, a plane at cruising altitude background noise is 78 - 84db. For automobiles is 70 - 85... similar in a supermarket. The world is loud. 

It took me decades to realize that trying to do high fidelity in those environments Is hopeless. While if you are in your home and there are some activities around and it is in the 50’s closed headphones can help. But if there is much noise the high fidelity is lost. 

I think lots of folks / reviewers go to a quiet room and evaluate earbuds and headphones. The problem is, if you are going to be using them in noisy areas, then this is not the right way to evaluate them. They need to have a completely different sonic balance to sound good. I finally realized this when I ditched my high end headphones, DAC, and battery powered headamp I used on airplanes while traveling and switched to Bose Quiet Comfort headphones where the sound is well balanced if somewhat cartoonish. It just sounds great... although not "audiophile".  I noticed that the system in my 4Runner is JBL and is punchy and actually sounds better than the Mark Levinson system in my Lexus (which, if you are sitting in the car in the garage sounds like a high end system). So car companies, headphone, and earbud companies are figuring this out. The sound needs to be crafted for the environment you are going to use them. 

Wireless IEM is an inherent compromise as you have to fit DAC, amp and battery in with the drivers. That is the advantage of cabled IEMs. Makes wired ones smaller and lighter as well, everything else assumed to be equal.

I second ghdprentice re isolation. I used to have Etymotics ER4s with the triple flange tips (some find them uncomfortable) and they isolate very well, including on airplanes. I upgraded to something "better" but still not happy with tips and resulting lack of isolation, e.g. in gym. Still experimenting ...

A little off the subject, but my B&W phones evidently have broken in after constant usage.  They now sound much better.  I didn’t know ear phones needed breaking-in.
