If you want over-ear headphones with up to 35 hours of battery life for DJ practice, choose Sony Noise Cancelling Headphones; if you need compact, in-ear Hi-Fi earbuds with head-tracked spatial audio, choose Technics Reference Class Hi-Fi. For DJ use, my decisive pick is Sony for longer listening sessions and a wired connection option, while Technics is the more portable choice for immersive everyday listening.
• Sony’s biggest strength: Over-ear noise cancellation, a 3.5 mm audio jack, and up to 35 hours of battery life. Trade-off: Its listed driver size is 30 mm, and the product is an over-ear headset rather than a compact earbud.
• Technics’ biggest strength: In-ear design with adaptive noise cancellation, Dolby Atmos with head tracking, and multipoint connection for three devices. Trade-off: Playback is listed as up to 10 hours with noise cancellation, or 28 hours with the charging case, and there is no headphone jack.
• Choose Sony if you want the longer stated battery life, hands-free calls, and the option to connect through a 3.5 mm cable.
• Choose Technics if you prioritize an in-ear fit, wireless charging, and spatial audio that responds to head movement.
• For DJ practice, Sony better suits someone who values an over-ear design and a wired connection; Technics better suits someone who wants a small wireless set for listening on the move.
Sony’s WH-CH710N is an over-ear Bluetooth headset with active noise cancellation. Its dual noise sensors automatically respond to the surrounding environment, and an Ambient Sound mode lets outside sound back in when you want more awareness. That combination is useful for switching between focused listening and situations where hearing what is happening around you matters.
The listed battery life is up to 35 hours. For everyday use, that gives Sony a clear advantage for long listening stretches between charges compared with the Technics’ stated 10 hours of playback with noise cancellation. Sony also supports USB Type-C quick charging: a 10-minute charge is specified to provide up to 60 minutes of playback. NFC one-touch pairing, Bluetooth streaming, voice-assistant access, and hands-free calling round out its practical travel-and-commute feature set.
For DJ practice, the 3.5 mm audio jack is a meaningful point in Sony’s favor. It provides a wired connection option, while Technics has no headphone jack. Sony’s adjustable metal sliders and over-ear shape may also appeal to someone who prefers headphones that sit around the ears rather than earbuds inside them. The trade-off is portability: this is a headset, not a small in-ear pair. The listed 30 mm dynamic drivers and 7 Hz–20,000 Hz frequency range describe its audio hardware, but those figures alone do not establish how it will sound for any particular mix or setup.

Who should skip this: Skip Sony if you specifically want true wireless earbuds, wireless charging, or Dolby Atmos head tracking.
Technics’ EAH-AZ100-N is a true wireless in-ear set built around compact listening rather than an over-ear fit. It offers adaptive noise cancellation, Bluetooth 5.3, and wireless charging through its case. Its standout feature is Dolby Atmos with head tracking: the audio presentation is designed to respond as you turn your head, a feature aimed at immersive music and movie listening rather than a conventional fixed stereo presentation.
Technics lists up to 10 hours of playback with noise cancellation enabled and up to 28 hours when including the charging case. Those figures make the case part of the battery picture: the earbuds themselves have a shorter stated playback span than Sony’s 35-hour figure, while the case extends total listening time. The product also supports multipoint connection for three devices, so it can suit someone who moves between a phone, computer, and another device without wanting to treat the earbuds as a one-device-only accessory.
Technics also describes its magnetic-fluid driver technology as intended to support accurate bass and smoother mid-to-high frequencies. Those are useful design details for shoppers considering a Hi-Fi-style listening set, but they are not a substitute for hearing the earbuds with your own music. There is no headphone jack, so a DJ who requires a wired connection should look closely at that limitation before choosing them.
Who should buy it: I’d consider Technics if you want wireless earbuds for commuting, calls, and immersive music or movie listening, with adaptive noise cancellation and three-device multipoint.
Who should skip this: Skip Technics if your DJ setup needs a 3.5 mm wired connection or if you want the longer single-charge battery figure listed for Sony.

• Best for quick charging details → Sony Noise Cancelling Headphones. Sony specifies up to 60 minutes of playback from a 10-minute USB Type-C charge.

Buying Considerations
First, think about the connection your DJ equipment requires. Sony’s 3.5 mm jack gives it a wired option, which can be a deciding factor for a setup that does not rely on Bluetooth. Technics is wireless only according to its listed connectivity, so its appeal is strongest when portability and wireless listening matter more than a cable connection.
Next, consider how you want the headphones to sit. Sony goes over the ears and has adjustable metal sliders. Technics is a true wireless in-ear design with a lower-profile shape intended to follow the ear’s contours. Neither form is universally more comfortable; the practical choice is the one that matches your fit preference and how long you expect to wear it.
Finally, match the audio features to the job. Technics’ Dolby Atmos head tracking is designed for an immersive presentation that responds to head movement. Sony instead emphasizes noise cancellation, Ambient Sound mode, and straightforward wireless or wired listening. If you are searching for the best hi res gaming headphones for dj, best hifi stereo head phones for dj, or hifi stereo gaming headphones for dj, these labels do not settle the choice: the useful distinction in the listed features is Sony’s wired option versus Technics’ spatial audio and compact wireless form.
I’d choose Sony Noise Cancelling Headphones for DJ practice because the 3.5 mm jack and up-to-35-hour battery figure better fit the needs I’d prioritize for longer sessions. Its over-ear design and Ambient Sound mode also make it a practical everyday headset beyond DJ use.
I’d choose Technics instead for a wireless, in-ear pair with Dolby Atmos head tracking and three-device multipoint. But for my DJ-focused pick, Sony is the more straightforward match.
For a DJ who needs a wired connection, Sony is the clearer fit because it has a 3.5 mm jack. Technics is wireless and has no headphone jack, though it offers in-ear portability and head-tracked spatial audio.
Sony lists up to 35 hours of battery life. Technics lists up to 10 hours of playback with noise cancellation, or up to 28 hours when its charging case is included.
Yes. Technics lists adaptive noise cancellation that responds to the environment. Sony also offers active noise cancellation, using dual noise sensors, and includes an Ambient Sound mode.
The listed features point to different priorities rather than a universal winner. Technics specifies a planar magnetic driver, a 20 Hz–40 kHz frequency range, and Dolby Atmos with head tracking; Sony lists 30 mm dynamic drivers and a 7 Hz–20,000 Hz frequency range. Choose based on whether you value Technics’ in-ear spatial-audio features or Sony’s over-ear design and wired option.
