Short answer: the Kiwi Ears Orchestra Lite. Both are rated 4.2/5 for sound quality (#182 and #209 of 450 in-ear headphones), and the Kiwi Ears Orchestra Lite costs $249 against $279.99 for the Tanchjim x Effect Audio Force, and with sound quality even, the cheaper one is the better buy.
Why pick the Kiwi Ears Orchestra Lite: Bass and lower midrange land within about 0.2 dB of the Harman target from 60 Hz to 1 kHz, so vocals and instruments sound natural and unboosted. Watch for: Presence from 3 to 6 kHz runs about 5.6 dB under target, with a 6.7 dB dip near 3.6 kHz, so voices and guitars sound recessed and a little veiled.
Buy the Kiwi Ears Orchestra Lite. Both are rated the same for sound quality, and it costs $30.99 less than the Tanchjim x Effect Audio Force.

Pros: Bass and lower midrange land within about 0.2 dB of the Harman target from 60 Hz to 1 kHz, so vocals and instruments sound natural and unboosted. The response is smooth, with a deviation of only about 2 dB around the target and a preference score of 76. Eight balanced armature drivers and 112 dB sensitivity make it easy to drive from a phone or portable player, and it suits warm and bass leaning tastes.
Cons: Presence from 3 to 6 kHz runs about 5.6 dB under target, with a 6.7 dB dip near 3.6 kHz, so voices and guitars sound recessed and a little veiled. Treble from 6 to 10 kHz is about 2.8 dB low, which softens cymbals and reduces sparkle. It is rated below the Etymotic EVO, and there is no built in microphone.
