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.
If you're looking for a cable with a unique sound profile in that it doesn't affect the frequency response much aside from a slightly leaner lower mids and smoother upper mids, but rather inflect the IEMs signature with a black background, tighter bass and sharper attack and faster decay then the Penon OSG should be at the top of your list!
If you're looking for a clear, bright and vibrant earbud with a lot of bite, superb soundstage with great separation and air and impressive resolution as well as fast and clean bass then the Rose Maria is the earbud you want to get!
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.
