If you want lightweight retro over-ear headphones with 20-hour playback, choose AUNMAS Retro Over Ear; if you need an open-air design with dual dynamic drivers, choose Serounder Over. For DJ use, I’d choose AUNMAS for its adjustable fit, while Serounder is the clearer match if you specifically want an open-ear listening style.
AUNMAS Retro Over Ear vs Serounder Over at a Glance
• Serounder Over: Open-air construction, dual dynamic drivers, and foldable, telescopic design make it distinctive for listeners who want airflow and a spatial sound presentation. Its trade-off is that its listed features do not specify a weight, so it is harder to compare directly on lightness.
• AUNMAS is for: listeners who want a lightweight, adjustable over-ear style and simultaneous connection to two devices.
• Serounder is for: listeners who prioritize open-air comfort, dual-device pairing, and a foldable design.
AUNMAS is the more straightforward fit for someone who wants a light pair of headphones for ordinary listening throughout the day. Its stated weight is 182g, and the curved metal headband, soft sponge cushions, and low clamping pressure are all aimed at keeping the fit comfortable. The extendable band and six-degree ear-cup adjustment give the design room to adapt to different head shapes and ear angles.
That adjustability could be useful for a DJ who wants headphones that can be positioned securely without an overly forceful clamp. The listed sound range is 80Hz to 20KHz, and the product description emphasizes balanced audio while allowing some ambient awareness. That makes AUNMAS worth considering for casual listening around the house or on a commute, though the supplied details do not establish it as a dedicated monitoring headphone. I would not treat a frequency range alone as proof of precise DJ cueing or isolation.
Battery life is a practical strength on paper: AUNMAS is specified for up to 20 hours of playback, with a wireless range of up to 10 meters. It can connect to two devices at once, which may suit someone moving between a phone and another device without wanting to manage a single-device setup. Its rotating left and right switch controls add a tactile, retro-inspired detail, but the data do not describe additional DJ-specific controls.

Who should skip it: Skip AUNMAS if your priority is an open-air design with explicitly listed dual dynamic drivers; those are Serounder’s defining features.
Serounder takes a different approach: its design is described as open-air, with suspended ear cushions intended to let air circulate. The product also says its silicone headband and ear pads are designed for comfort, while the construction avoids ear-canal pressure and keeps the listener more aware of their surroundings. For someone who dislikes a closed-in listening feel, that combination may be appealing during leisure time or movement.
Its sound setup is the clearest point of distinction. Serounder lists dual dynamic drivers and independent amplification, with a stated aim of delivering crisp vocals, deep bass, and a spacious presentation. Those details may interest a DJ who values a broader-feeling sound for listening between sessions. However, the available information does not specify a frequency range, noise isolation, or a dedicated DJ monitoring mode, so I would not assume it is the right tool for precise cueing in a loud environment.
Serounder also lists up to 20 hours of playback, a wireless range of up to 10 meters, and the ability to pair with two devices. Its foldable and telescopic design gives it some flexibility for storage and fit adjustment. The listed product dimensions are approximately 190 × 142 × 90mm, but no weight is supplied, making a direct weight comparison with AUNMAS’s 182g less certain. Sweat-related silicone construction is mentioned, though the supplied details do not state a waterproof rating.
Who should skip it: Skip Serounder if a known lightweight figure and a soft-cushion, adjustable metal-headband design matter more to you than open-air construction.

• Best for foldable storage → Serounder Over. Folding and telescopic adjustment are listed features.

My Verdict
In my opinion, I’d buy AUNMAS Retro Over Ear for general listening and DJ use because its 182g weight, adjustable band, and six-degree ear-cup adjustment give me clearer fit information to work with.
For DJ use, I would not mistake either product’s listed features for a dedicated monitoring specification.
My pick is AUNMAS, with Serounder as the better fit for someone who specifically wants an open-air design.
The biggest decision is not battery life or wireless range: both products list up to 20 hours of playback and a range of up to 10 meters. Both also support a connection to two devices at once. If those are your main requirements, the listed specifications do not give either product a clear advantage.
Instead, consider how you want the headphones to sit and what you expect from the listening experience. AUNMAS gives a specific weight, soft sponge cushions, an adjustable metal headband, and rotating controls. Serounder emphasizes airflow, suspended cushions, silicone contact points, and dual dynamic drivers. Those are meaningful differences, but they describe different design priorities rather than proving that one will sound better for every listener.
For DJ use, be especially careful about interpreting category phrases. Searches for “transparency mode bone conduction headphones for dj” or “true wireless earbuds for dj” describe different listening styles from the over-ear designs compared here. Neither product is identified in the supplied details as bone-conduction headphones or true wireless earbuds. Likewise, the phrase “best crystal clear calls kids headphones for dj” combines several needs, but these specifications do not provide call-quality measurements or establish either product as a children’s model.
If you’re deciding based on comfort, Serounder’s suspended cushions and silicone pads may appeal if airflow is important, while AUNMAS offers a stated weight and a more detailed description of headband and ear-cup adjustment. If storage matters, Serounder is explicitly foldable and telescopic. If you want a familiar retro-inspired control detail, AUNMAS has the listed rotating switches. For either product, check the current price on Amazon before deciding; I’m not comparing them by price here.
AUNMAS has a stated 182g weight and adjustable fit, while Serounder has an open-air design and listed dual dynamic drivers. Neither product’s supplied details specify dedicated DJ monitoring features, so choose based on fit versus open-air design.
Both are listed with up to 20 hours of playback and a wireless range of up to 10 meters. Both also support connection to two devices at once.
The supplied details describe an open-air design that allows airflow and supports situational awareness. They do not specify noise cancellation or a feature called transparency mode.
Serounder lists a foldable, telescopic design, which may help with storage and adjustment. AUNMAS lists an extendable headband and six-degree ear-cup adjustment, but its supplied details do not describe it as foldable.
