Our take on the brand
Product Strengths
- Unique octagonal design made of quality materials, with a rugged, serviceable build quality featuring exposed nuts and bolts.
- Surprising amount of bass for an open-back, on-ear headphone, that is solid, tangible, present, well balanced and well tuned.
- The silver-plated OCC copper cable is lightweight, pliable, ergonomic and does not remain bent after staying still.
- Comfortable on-ear headphone, especially considering it's an on-ear design, with thick, soft pads and a comfortable headband.
- Easy to drive with portable devices like dongles or smartphones.
Product Considerations
- Being an on-ear design, the Thalia can become uncomfortable after extended listening sessions (45 minutes or longer) due to pressure on the ears.
- Not the most compact headphone, and does not fold up, limiting its portability somewhat.
- The open-back design results in sound leakage, making it less suitable for noisy environments or situations where discretion is required.
- The height adjustment mechanism, while providing fine control, is a bit fiddly and not easily adjustable on the fly.
- Its lower-midrange will be too full for some.
Comparisons (according to reviewers)
- The Thalia is far superior to the Koss Porta Pro and sets a new standard for portable on-ear headphones, but it is inspired by the Porta Pro.
- Compared to the Grado RS2x, the Thalia is more durable, comfortable, and more enjoyable overall, and is more bassy and thicker in the midrange.
- The Thalia has a faster pace and a better driver control, and offers a lot more in the top-octave than the Sennheiser Momentum 2/3.
Takeaway: The Thalia is a uniquely designed, portable on-ear headphone that delivers great sound and is built to last. It is a good option for those who want a distinctive headphone that is fun to listen to.

- Comfortable for long listening sessions
