If you're looking for an immersive IEM with holographic soundstage, deep powerful bass with excellent punch and control, a forward and articulate yet velvety midrange with rich textures and last but not least engaging treble with excellent extension then look no further, Zen will offer countless hours of musical bliss!
If you're looking for a highly engaging comfortable IEM with excellent craftsmanship, with punchy, quick and dense bass for a superb sense of rhytm, full bodied mids with bite and emotional vocals as well as energetic and well extended treble then at this price point the Insects Awaken is a no brainer in my opinion!
If you're looking for a solid technical performer with a reference tuning at a reasonable price, boasting strong bass foundations, articulate and clear mids as well as energetic and well extended treble that provide both excellent resolution and imaging then the Spring 2 is a strong option in the lower price tier!
If you're looking for an IEM that boasts one of the best soundstage at any price, features powerful, clean and quick bass with excellent control as well as a clear, open an articulate midrange and a well extended and engaging natural sounding treble then the FD5 is a no brainer! If you own a good copper cable I strongly suggest you plug it to the FD5 as it will be a more relaxed yet engaging listen and if you don't it's worth spending the extra money unless you enjoy a more energetic and brighter midrange. I would stick to the larger nozzle as the narrower brings most of the benefits a copper cable brings with the downside of making the soundstage smaller and penalizing the upper treble presence and the engaging lower treble.
If you're looking for flagship performance at a reasonable price and you like full bodied, smooth signature with strong bass foundations, impressive resolution and treble refinement then you'd miss out not adding the Volt to your list. Make sure you have a proper source though to provide enough current to bring the best out of it. And if you have a bigger budget, Totem is a fantastic pairing that brings a more punchy, energetic, focused presentation as well as elite performance that matches much pricier flagships.
If you're looking for a decently priced well built IEM with great slam and physicality down low, a full and smooth midrange, refined and energetic treble then the OH10 is worthy to add to the list of IEMs to consider. If you can spare the 59€ extra their CTU-01 balanced cable is strong value and a good match to the OH10 to take it one step further.
If you're looking for a decently priced well built IEM with good slam and physicality down low, a clear articulate and accurate midrange and treble with smooth delivery then it's hard not to recommend to add the OH1 to the list of IEMs to seriously consider. If you can spare the 59€ extra their CTU-01 balanced cable is strong value and a superb match to the OH1 to take it one setp further and frankly with a SQ punching above its price point.
The Orb is up there with the best in the segment namely ISN H40 and Dunu DK-2001 which is no small feat. If you're looking for an IEM with of the very best bass, a full yet clear articulate midrange and refined treble then it's hard not to recommend the Orb as one of the very best value for money on the market. A no brainer in my opinion!
If you're looking for a highly coherent reference IEM with superb transparency, resolution and imaging all with a smooth delivery and a level of refinement rarely found at its price point then you will enjoy the LZ A7 with its default black filter but the silver filter in monitor mode will go even further reaching performance levels beyond what you'd expect at this price point. If you like a warmer tone and slightly more relaxed variant the Gold filter will definitely do, without compromising the baseline qualities. If you're into brighter signature, the blue filter will be an interesting option and conversely the red filter will provide a darker and warmer tuning.
If you're looking for a superbly built IEM with a reference baseline beautifully spiced with a subtle touch of organic that you can adjust with the flick of a switch, then the SA6 holds fantastic value for the price and will be tough to beat! It packs impressive resolution and a remarkable tonal accuracy across the range. A very engaging reference IEM, that follows in the footstep of hallmark IEMs such as the InEar Prophile 8 at a fraction of the price.
If you're looking for an engaging entry level reference IEM with solid technical foundations and an emphasis on vocals, along with good sub bass extension and rumble then the SA3 should definitely be on your list! If you want a more organic take and can afford mid tier pricing then check out the SA6.
If you're looking for a budget IEM that packs excellent and punchy bass, smooth mids and energetic treble with good sparkle and shimmer the TFZ No3 19th is quite the engaging listen and impressive performer at the price granted you feed it appropriate power which out of DAPs will mean reaching for a balanced cable.
If you're looking for a relaxing yet fun IEM with very good bass slam, full bodied mids with good upper mids bite then the TFZ My Love III deserves your consideration. If you have a decently powerful source like the DX160 or Lotoo PAW S1, running the My Love III balanced shows that its graphene driver will scale up nicely to take it several notches up.
If you're looking for an IEM that is highly engaging and smooth with a strong bassline, full mids with superb vocals and very refined and elegant treble then the C9 Pro is definitely among the top options especially at its price point!
