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!
Ikko OH10 – Obsidian
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.
Ikko OH1 – Meteor
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.
If you're looking for cable that brings an organic signature with extra texture down low, a nice lower mids boost and a smooth delivery across the range combined with a nice separation and stage size expansion that only an 8 wire can provide then at this price the AG8 is to me a no brainer!
Dunu SA3 – Vocal reference
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.
TFZ n°3 – 19th
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.
TFZ My Love III
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.
ISN H40 – Smooth & punchy fun!
If you're looking for a warm, engaging, fun and punchy IEM that you can listen for hours without fatigue, with a huge soundstage and good resolution then you'd be hard pressed to find a better IEM for the price (and much more)!
Penon BS1 – Good things come in small packages!
If you're looking for an earbud with great soundstage, powerful bass with great rumble, full bodied mids with beautiful vocals and smooth yet energetic and refined treble then the Penon BS1 definitely should be on your list especially at its price point!
