What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- Open-back design provides a wide soundstage, sometimes described as industry-leading for a Bluetooth headphone.
- The BlueMini Bluetooth adapter is convenient, versatile, and provides good value as a wireless balanced DAC/amp module.
- Comfortable to wear, with large ear holes and soft earpads accommodating various ear sizes.
- A wired-only version has been released at a lower price, making it more attractive for wired listening.
- Offers multiple connectivity options: wired (analog and digital via USB), and wireless (Bluetooth).
Product Considerations
- Bass response may be lacking for bass enthusiasts, described as 'sucking' or 'rolling off' in some reviews.
- Treble can be bright and sibilant, and potentially 'hashy', especially at higher volumes or with certain pairings.
- The build quality, while decent, uses more plastic than some competitors like the Sundara.
- The stock cable is stiff and can produce microphonics.
- The included Blue Mini Bluetooth adapter lacks advanced features like volume control or track skipping.
Comparisons (according to reviewers)
- Vs. Hifiman Sundara: The Sundara generally offers better overall sound quality, detail, vocal presentation, and bass (when both are wired), but the Deva with BlueMini gets very close.
- Vs. Hifiman HE400/HE400i: The Deva is better overall when using the BlueMini, especially compared to HE400.
- Vs. Sennheiser HD 6XX/650: The Deva is similar in some ways to the HD 6XX, with a comparable sound signature, but the HD6XX may be smoother in some respects, the HD6XX bass tends to be muddy, while the Deva has a tighter controlled base.
- Vs. AKG K712 Pro: The Deva is tuned closer to the HD 6XX and the 712 Pro but has a narrower soundstage, the 712 Pro has fun articulate bass.
Takeaway: The Hifiman Deva is a versatile headphone that offers a unique blend of open-back planar sound with convenient Bluetooth connectivity, making it a worthwhile consideration for those seeking a convenient and good-sounding listening experience, especially at home or in the office. The inclusion of the BlueMini offers great value as both a Bluetooth receiver and a DAC/Amp, which lets the Deva sound great when wired to a great amp or even just as a DAC to your computer.
