Working on the review of Tanchjim Oxygen - latest double chamber dynamic driver IEMs from this brand. They release products rarely but aptly... Last time it was Darkside IEMs with good lower end extension and warmth across the AFR. Oxigen is a newer model with quite a cost. First impression is very good - good package, built quality is perfect, excellent fit and shape inherited from the previous model. Getting ready to sound quality tests. Full review would show up soon. Couple of photos now:
