Product Considerations

- If treble-sensitive, caution is suggested as it might be too bright
- The provided case may be underwhelming given the product's price
Comparisons (according to reviewers)

Video review
Our take on the brand
Product Strengths
- The Valhalla is the best IEM that Thieaudio has made to date.
- It delivers endgame tuning with tasteful bass response, a sweet and clean midrange, and treble that feels airy and highly detailed.
- Midrange is perhaps the Valhalla’s biggest strength, with incredible detail, layering, and separation.
- The sound signature is very well balanced, offering a clean, highly cohesive, transparent and spacious delivery that’s also engaging and musical.
- The bass part has really solid low emphasis, with a wide soundstage, impressive sub-bass extension and clean emphasis on the sub-bass, while the mid-bass is more restrained but still delivers good thickness.
Product Considerations
- The cable design is not as emphatic with Vahalla, similar to the Origin cable, but it's not something new which should come with a flagship IEM.
- The unboxing experience feels no different from other Thieaudio products, and the accessories are almost the same that were shipped with the Origin, which is less than half the price of Valhalla.
- The shells are larger than typical IEMs, and the size may present a challenge, especially for those who have smaller earlobes.
- The puck-style carry case has limited space inside, making it hard to store the IEMs and the cable properly.
Comparisons (according to reviewers)
- Vs Origin: Valhalla offers a more natural reproduction of the music, and the bass is better, not by much, but it is better, with better quality bass.
- Vs Monarch MK3: The bass is better on the Valhalla, and the detail, the layering, the masking, the note weight, as well as the sibilance are also better.
Takeaway: The Thieaudio Valhalla is a high-end IEM that offers excellent sound quality across the board. For those who want a well-rounded IEM that delivers a detailed and engaging listening experience, the Valhalla is a great option.

Video review
Our take on the brand
Our Summary
Product Strengths
- Beautiful and unique faceplate design, described as a 'galactic design' with a 'solar flare, jellyfish looking thing,' with a stunning finish that is as good as any other premium earphone
- High-quality drivers, including Knolls Ultra Tweeters and Sonion drivers, result in exceptional music playback
- More texture and punch in the bass compared to the Hype 4 is provided, with increased texture and speed of attack in the bass
- Better instrument separation and layering, especially for orchestral music, leads to a more beautiful listening experience
- Clean and natural timbre, with stunning male and female vocal reproduction and distinct separation from instruments is provided
Product Considerations
- Can be a little bit spicy with gunshots and explosions, and the separation and layering are not quite there in gaming, making it less ideal for competitive gaming scenarios
- Its shell is large, which may be uncomfortable, especially for users with small ears, and it may only be comfortable to wear for around one hour
- The included case is too big for an IEM and lacks inlay, so the IEMs bounce around inside
- Stock tips must be used to get the best sound quality, and the sound is worse when deeply inserted
- Treble is BA treble that is not as impressive compared to other IEMs in its price range
Comparisons (according to reviewers)
- Vs Hype 10: Provides more textured bass, better instrument separation, and a slightly bigger soundstage, making it a more noticeable difference for music
- Vs Supernova: The Supernova provides better mid-range and better vocals compared to the Hype 10
- Vs Monarch MKII: The Hype 10 has better bass performance, but the Monarch MKII is better technically
Takeaway: The Hype 10 is a stunning IEM with excellent drivers and a unique design that will provide great separation. If a bump in textured bass is desired, this could be the IEM for you.
