Short answer: the Sennheiser IE 200. It ranks #14 of 115 in-ear headphones by sound quality, rated 4.4/5, at $129.95; the Sennheiser IE 600 ranks #56, rated 3.5/5, and costs $699.95, so there is little reason to consider the other one.
The Sennheiser IE 200 is the better-sounding pick. 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. Watch for: 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.
Why pick the Sennheiser IE 600: Sub-bass extends to 20 Hz with a slight 1.7 dB lift, and bass, low mids and upper mids all sit within about 1.3 dB of target, so the core of most music sounds full and natural. The tradeoff: In oratory1990’s measurement a 7.6 dB dip near 5.9 kHz and a presence band 5.5 dB under target take bite out of vocals and guitars, while a 4.7 dB peak near 9.7 kHz can sound sharp.
Buy the Sennheiser IE 200. It is rated higher for sound quality than the Sennheiser IE 600 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Headphones In Full
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.

Sennheiser IE 600: $699.95 B&H Photo Video eBay
Pros: Sub-bass extends to 20 Hz with a slight 1.7 dB lift, and bass, low mids and upper mids all sit within about 1.3 dB of target, so the core of most music sounds full and natural. Air above 10 kHz is lifted about 5.6 dB, adding sparkle to cymbals and room sound. At 118 dB/V it is easy to drive from a phone, and it suits listeners who like a bassy or warm tilt.
Cons: In oratory1990’s measurement a 7.6 dB dip near 5.9 kHz and a presence band 5.5 dB under target take bite out of vocals and guitars, while a 4.7 dB peak near 9.7 kHz can sound sharp. The FiiO FD5 and iBasso IT04 both carry higher ratings for considerably less money.
