Short answer: the TRN MT5. It ranks #171 of 450 in-ear headphones by sound quality, rated 4.3/5, at $14.99; the CCA Polaris ranks #231, rated 4.1/5, at $13. The price gap is small enough that the sound-quality ranking should decide it.
Buy the TRN MT5. It is rated higher for sound quality, and saving $1.99 with the CCA Polaris does not make up for the sound-quality gap.
