These lists are important probibly because people find out about the reputation of certain IEMs and can investigate. Still I pretty much think that there are way more variables than a simple list. Taking into account after market cables, DAP or DAC-amp-source; in many ways helps folks nurture the sound they are looking for..........raising the IEMs overall value and performance quota in the end. This hobby is so crazy detailed that even the selection of tip plays an important role affecting the end sound and fit. Folks obviously have sold IEMs simply due to a bad fit, and in contrast folks have fallen in love with an IEM, starting simply over fit qualities. 1) qdc Anole V3 ($500-$600) Han Sound Audio Zen 4 wire OCC litz copper cable terminated Furutech 4.4mm An extremely underrated IEM probibly due to underexposure and lack of availability in the US. A small broken English web site does not help, along with $100 shipping fees doesn’t add to the feel good experience. Take note QDC is the China military audio provider, hence qdc is the retail segment with Chinese military technology making a splash up and down the qdc line. I have heard most of the line except the new 10BA per side flagship. Still the 3BA Anole V3 delivers a dark but cohesive-collected signature, although thick, it does bass better than any BA IEM I have ever heard. Along with two small switches the tone can be altered, though even in stock mode this IEM delivers an L shaped signature good with rock and EDM. The correct DAP and cable help bring some tone character out of the woods which would normally be hidden if ran off a phone. It’s just detailed enough in the mids and treble, though nothing sparkles or shimmers, it’s all about natural timbre and bass energy in the end. Custom house made BA drivers X3 per side. Pair it with the wrong DAP and it runs a chance of being boring, but get it an enthusiastic signal (1Z) and it’s a signature which can pamper your ears for hours on end yet never seems to get old. 2) Sony Z5 ($500............used to be way more $) Sony MUC-M12NB1 Headphone Cable 4.4mm Pentaconn-MMCX Best advise is never attempt to hook up the rubber (hell) stock cables and save your MMCX cable change-out cycles going right to aftermarket. This IEM hangs out of your ear like a USB drive though Triple Comfort Tips help hold them in place. Once you get over the ergonomics this IEM rules with a powerful source. Don’t get it enough juice and you’ll never learn what it’s about. It also can keep scaling way past DAP quality and show what’s up with premium desktop gear. It’s that good. Custom house made BA drivers X 2 and a single DD per side. 3) Nobel Kaiser 10 Encore ($1850) Perfectly and technically neutral with a slight hint of warmth and a boost in the mids. Just a really fast big soundstage showing some detail though not the most detail ever. Bass fall off is fast as you would expect with 10 BAs per ear. Though get it a good music genre and it performs at it’s price level. Probibly best with classical, vocal and rock. Falls short getting the goods delivered with bass heavy EDM, though may be your cup of tea if you like that fast-bass character. It’s a very complementary IEM to some thick bass heavy IEMs in your collection. Overall it’s the most technical in my list, and somehow takes what it does and spreads the musical information out and about reaching a profound level of clarity. I rate it number three as I like the bass tone of the top two better. Still the Encore is special (a keeper) and does what it does magically. Custom house made BA drivers at 10 per side. I have heard hundreds of IEMs in store demo mode, though don’t feel confident to relate my opinions about them.
