Short answer: a tie on sound quality. Both are rated 4.4/5 (#109 and #90 of 450 in-ear headphones) at nearly the same price ($129 vs $129.95), so choose on features and fit.
The case for the Queen of Audio Ryusei: Its single dynamic driver earns a preference score of 78.8 and a smooth 1.37 dB spread in the median of 4 squig.link measurements. The catch: Presence drops about 4.1 dB below target, softening vocal edge and snare attack.
The case for the Sennheiser IE 200: Bass and midrange land almost exactly on the Harman target in oratory1990’s measurement, within about 0.5 dB from 60 Hz to 3 kHz, which gives a natural tonal balance and a preference score of 79. The tradeoff: The presence region from 3 to 6 kHz sits about 5 dB under target, with a 5.7 dB dip near 4.4 kHz, so vocals and snare attacks sound a little recessed.
Buy the Queen of Audio Ryusei or the Sennheiser IE 200 on features: they are rated the same for sound quality at close to the same price.

The Two Headphones In Full
Queen of Audio Ryusei: $129.00 Bloom Audio eBay
Pros: Its single dynamic driver earns a preference score of 78.8 and a smooth 1.37 dB spread in the median of 4 squig.link measurements. Bass rises about 3.3 dB above target between 60 and 200 Hz, giving rich, punchy low end and warmth that suits bassy and warm tastes. Upper mids stay on target, so vocals keep their natural tone.
Cons: Presence drops about 4.1 dB below target, softening vocal edge and snare attack. Treble is uneven, with a 6.5 dB peak near 8.4 kHz that can sharpen sibilance and a 5.5 dB dip near 11 kHz that trims air, and the low mids run 1.3 dB hot, adding some thickness.

Sennheiser IE 200: $129.95 Amazon eBay
Pros: Bass and midrange land almost exactly on the Harman target in oratory1990’s measurement, within about 0.5 dB from 60 Hz to 3 kHz, which gives a natural tonal balance and a preference score of 79. At 16 ohms and 119 dB SPL/V sensitivity it plays loud straight from a phone with no amp. Each earpiece weighs only 4 g, and the single 7mm dynamic driver is a simple, wired design with no battery to charge.
Cons: The presence region from 3 to 6 kHz sits about 5 dB under target, with a 5.7 dB dip near 4.4 kHz, so vocals and snare attacks sound a little recessed. The top octave runs about 5.8 dB hot, which adds sparkle that can read as thin or bright on some recordings. The Final Audio A4000 and Shuoer S12 carry higher ratings at lower prices.
