The Ikko OH1 is sensitive to power so it is recommended to use it with stronger outputs for a more controlled and balanced bass performance. A little disclaimer, if the Ikko OH1 is used with weak outputs, you may hear a hollow sound, a sign that it is lacking in bass.
Ikko OH1 Vocal Tips. The V-shaped response of the Ikko OH1 shows its hybrid performance on mid-tier DAPs. Guitars and other stringed instruments may sound narrow and the staging width may also fall on the average level. However, the Ikko OH1 will never be sporting a flat sound or pose a discussion that it is lacking in dynamics. When used with the vocal tips, the Ikko OH1 sounds awesome with relaxing jazz music or instrumentals but ironically, you may observe a significant comparison with its hollow performance for tracks that are focused on vocals.
There is a comfortable but slow bass decay with a slight dip in the mid-lows so some vocals will image a little further back. The OH1 with the vocal tips sound great with instrumentals or relaxing jazz music but maybe slightly hollow in its performance for vocal focused tracks.
So that concludes our in depth review of the Ikko OH1. With a retail price of $139, the Ikko OH1 has a competitive price tag that offers anodized metal housings and above average build quality.
What We Like: We like the build quality, great clarity and separation of the Ikko OH1
What We Don’t Like: We’re not really sold out with the carrying case that doesn’t keep the earpieces separated. Plus, the upper mids can sound a bit harsh and the U shape is not a fine reference for tuning.
