I can definitely say, that I'm in love with this tiny and inexpensive earphones, made by Trinity Audio Engineering, so once again I need to gather my poor english skills to share my love with you.
I won't write much about Trinity itself, they are active participants in Head-Fi community, I can only notice, that most of all I like their passion for experiments, necessary for all companies that wants to succeed. If you are interested in getting more information about company,
here is excellent thread.
Also, I won't spend lot of time, describing box, accessories set and other aesthetic stuff. You can definitely see Hyperion's design on pictures, accessories set includes case, shirt clip, 4 pairs of single-flange tips, 1 pair of dual flange and adapter, to change straight jack into 90° one. Hyperion's build is nice, despite being really affordable model, they made of metal, have pretty robust cable and nice sturdy jack. They fit nicely into any ears and sits there without any comfort issues. Only disadvantage I've noticed — slight microphonics, when cable touches your cloth. Luckily, shirt clip and over-ear wearing comes to the rescue.
So, that's all about outlook, main thing here is sound, and it's really nice.
I've burnt this earphones for 48 hours, not that I believe it can change anything, but just to be sure.
As lots of small earphones, Hyperion's sound really fit-dependant. You should try different tips to ensure perfect sealing. For me best option became white two-flanges. I've heart good words about foam tips, but I didn't try them.
Trinity managed to get nice, "tasty" sound with slight accent on lows and great mids. Earphones sound representation is really nice for their price, and suits almost all genres.
Bass have a slight emphasis, to create necessary effect of tightness. It's not going really deep, but offers good resolution for this price range. Bass speed greatly depends on source capabilities, so with DAPs that dosn't control lows greatly, Hyperion can be slightly boomy, but with good DAPs, there is no any issues.
Mids are especially nice for such inexpensive model. Their mids are lively, it's smoothed a little to create more "musical" representation, and it sounds really nice. Stage is a bit wider then average, but not really deep. Instrument separation is also OK.
Highs are rolled off a little, to make sound comfortable and not fatiguing, but there are enough of them to represent treble. Hyperion's sound isn't the most airy one, but it's not harsh and too bright.
So, if I don't mind the price, there are some slight drawbacks in Hypreion's sound, but price-wise, they are more then good. BTW, if you go to Trinite Audio thread, you can find there coupon for really great discount.
You can definitely use those earphones with smartphones and tablets (they have microphone with 1-button talk control), but Hyperions can really benefit from nice DAP. They have growth potential and improves sound with mid-tier DAPs. They are pretty OK with almost all music styles (of course, for orchestral classic or technical metal you should consider something much more expensive). Earphones are pretty forgiving, so you can listen to not-audiopiliac recirdings with ease.
To conclude: if you are looking for inexpensive earphones with balanced and fun sound, Hyperion is really nice option.
I want to thank to Trinity Audio Engineering for providing me a review unit in exchange of my honest opinion.
