Avantree SP850 vs beyerdynamic DT 990 PRO 80 Ohm: Which Should You Buy?

The SP850 is geared for quick everyday use: auto-scan helps populate stations, and holding number keys saves favorites for easy recall. Customer feedback also calls it easy to use and simple to set up. The tradeoff is that SD navigation and shuffle behavior can take some getting used to.

The DT 990 PRO is straightforward because it’s wired: connect it to a compatible output and listen. Usability concerns are more about preferences and setup context—open-back usage (quiet room), potential treble sensitivity, and the non-detachable cable—rather than menus or controls.

Design priorities differ sharply. The Avantree SP850 focuses on pocket-size practicality, an LED display, and handheld use, with a strap that reviewers find helpful for carrying or positioning for reception.

The DT 990 PRO focuses on over-ear comfort and listening ergonomics with circumaural velour pads and a lightweight feel designed for long sessions. Its open-back design supports soundstage but sacrifices isolation, making the design best suited to quiet environments rather than commuting or shared spaces.

The DT 990 PRO rates higher for build quality and durability in the provided scoring, and many reviews praise its construction and long-term serviceability. Some users do report durability issues (including plastic breakage), so it’s not universally perfect, but overall it’s positioned as a professional, repairable design.

The Avantree SP850 uses a plastic enclosure and is designed to be lightweight and portable. Reviews highlight solid day-to-day satisfaction, but it scores lower for build quality, consistent with a compact consumer device aimed more at convenience than heavy-duty studio hardware.

The DT 990 PRO scores higher for durability and is positioned as a serviceable, long-life studio design, although some users still report physical issues. The SP850 is a lightweight portable device with a plastic enclosure; it’s easier to carry daily, but it’s not aimed at the same rugged, repairable pro-hardware standard.

The Avantree SP850 is the clear portability winner: pocket-size dimensions, light weight, and battery power make it suited for walks and moving room-to-room. The DT 990 PRO is portable in the sense that it can be carried, but its full-size open-back design and long cable make it better as a home/studio headphone than an everyday travel companion.

The Avantree SP850 wins on features because it is a standalone playback device: FM tuner with auto-scan, numeric preset keys, Bluetooth speaker functionality, SD card MP3 mode, an LED display, and both headphone and AUX connections.

The DT 990 PRO is feature-light by design: it focuses on the core headphone experience with an open-back structure, 80-ohm impedance, and a wired connection (3.5mm with a threaded 1/4" adapter). If you want modes, presets, and independent playback, SP850 is the more feature-rich product; if you want a purpose-built monitoring headphone, DT 990 PRO keeps it simple.

The Avantree SP850 has limited smart features beyond multi-mode playback and scanning/presets. The DT 990 PRO does not emphasize smart features and focuses on traditional wired headphone listening.

Setup is easy on both. The SP850 typically involves charging, running FM auto-scan (optional), saving presets, and pairing Bluetooth when needed. The DT 990 PRO is essentially plug-and-play: connect the 3.5mm jack (or use the threaded 1/4" adapter) and start listening.

The SP850 is compatible with phones, tablets, PCs, and headphones via Bluetooth and 3.5mm connections, and it can play MP3s directly from an SD card. The DT 990 PRO is broadly compatible with devices that provide a 3.5mm or 1/4" headphone output (adapter included), and is also listed as compatible with consoles, laptops, tablets, and music production equipment.

The Avantree SP850 includes an LED display for mode/status and playback info, but display quality is not a primary strength and is scored modestly. The DT 990 PRO has no display.

Audio quality is the clearest separation. The DT 990 PRO scores substantially higher for audio and is repeatedly described as detailed with strong soundstage and imaging—qualities that matter for mixing decisions and competitive gaming cues. Some listeners find the treble bright and may prefer EQ depending on sensitivity.

The Avantree SP850 is praised for clear sound for its size and balanced voice-focused listening. It’s well suited to radio programs and close-range music, but it’s not intended to compete with dedicated high-fidelity headphones for resolution, staging, or critical monitoring accuracy.

The Avantree SP850 offers the most connectivity flexibility: Bluetooth for wireless streaming plus 3.5mm headphone and AUX connections, along with SD card playback for device-free listening.

The DT 990 PRO is wired only, using a 3.5mm plug and including a threaded 1/4" adapter for studio gear. This is ideal for reliable low-latency listening, but it doesn’t cover wireless use cases.

The Avantree SP850 is battery powered with USB charging and is built for portable use away from outlets; customer feedback mentions rechargeable runtime around the 6-hour range depending on use. The DT 990 PRO has no battery because it’s a wired headphone, so runtime depends on your playback device rather than the headphones themselves.

The Avantree SP850 is designed around battery power and USB charging; feedback suggests practical runtime for casual portable use. The DT 990 PRO doesn’t use a battery, so “power efficiency” is mainly about your source device and listening volume rather than the headphones themselves.

Value is close by score, with a slight edge to the DT 990 PRO. If you judge value by audio performance and long-session comfort, DT 990 PRO’s strong sound and studio orientation can justify its position despite the non-detachable cable and treble sensitivity for some listeners.

If you judge value by how many listening scenarios one device covers, the SP850 is compelling because it combines FM radio, Bluetooth speaker use, SD playback, and rechargeable portability. Neither is “better value” in a vacuum—each is best value when matched to its intended use.

The beyerdynamic DT 990 PRO scores higher for brand trust and is positioned as a long-established pro-audio brand with serviceable parts. Avantree also scores well for brand trust in this dataset, and at least one detailed review specifically praises responsive support and a replacement experience. Overall, brand confidence appears stronger on the beyerdynamic side, with solid evidence of support on the Avantree side.

Both products are well received. The Avantree SP850 has a very large review base (12,090) with a 4.4/5 rating and strong satisfaction scoring, commonly praised for sound quality for its size, ease of use, and battery life, with mixed reception feedback.

The DT 990 PRO has a higher 4.6/5 rating across 3,498 reviews and a higher satisfaction score, with praise centered on clarity, comfort, and gaming performance, while recurring critiques include fit clamp for some users, treble brightness, and the non-detachable cable.

Warranty/support clarity is limited in the provided data. The Avantree SP850 has a stronger warranty/support score, and one review explicitly describes a successful warranty-style replacement experience after extended use. The DT 990 PRO has a lower warranty/support score in this dataset, and no specific warranty terms are provided in the product details shown here.
