If you want over-ear sound isolation and a wired monitoring headphone, choose Amazon Renewed Beyerdynamic DT 770; if you need compact in-ear listening from a 3.5 mm jack, choose Generic Sonicast direm E3. For commuting, I’d favor the E3 for its smaller in-ear format, while the DT 770 is the more natural pick for a seated listen with room for over-ear headphones.
Amazon Renewed Beyerdynamic DT 770 vs Generic Sonicast direm E3 at a Glance
• Amazon Renewed Beyerdynamic DT 770: Closed-back, around-ear design with sound isolation and a 3 m coiled cable; its 250-ohm configuration is intended for high-powered gear, so it is not the obvious choice for every mobile setup.
• Generic Sonicast direm E3: Wired in-ear design with a 3.5 mm analog connection and a flexible, tangle-resistant fabric cable; it does not have the DT 770’s over-ear fit.
• Choose the DT 770 if you want a full-size headphone for studio monitoring, editing, or focused listening and have gear suited to its 250-ohm impedance.
• Choose the E3 if you want wired earbuds for compatible 3.5 mm devices, including a phone, laptop, or handheld gaming device with that jack.
• These are not interchangeable versions of the same kind of headphone. One is a large, closed-back over-ear model whose supplied configuration is 250 ohms. The other is a compact, wired in-ear pair built around a single acoustic driver. For commuting, those differences matter more than broad claims about sound quality: a headphone you can connect to your device and comfortably wear is more useful than one with a feature set that does not fit your trip.
The DT 770 is the full-size choice here. Its closed-back, around-ear design and listed sound isolation make it a sensible option for someone who wants to concentrate on music, monitoring, or editing without choosing an open-back headphone. It is wired, has a 3.5 mm headphone connection, and comes with a 3 m coiled cable. That cable can be convenient near a desk or audio interface, but it is a lot of cable for a quick walk or a crowded commute.
The key detail is impedance. This listing is for the 250-ohm model, which is described as intended for high-end studio equipment and headphone amplifiers. The product information lists a 250-ohm impedance, 96 dB sensitivity, a dynamic driver, and a frequency range of 5–35,000 Hz. Those figures identify the listed configuration; they do not mean every phone or portable device will be an ideal match. The product description also refers to an 80-ohm DT 770 for studio use or listening on the move, while the featured model details specify 250 ohms. I would make the actual model and impedance the first thing to check before choosing this listing for portable use.

The direm E3 takes the opposite approach: it is a wired in-ear headphone with a 3.5 mm analog connection. That makes its form factor easier to consider for a commute than a large over-ear set, provided your device has a compatible jack. It is also listed for use with devices such as PCs, laptops, consoles, and handheld systems. The useful practical point is simple: check the connection on the device you plan to use, rather than assuming every phone or gaming device has a 3.5 mm port.
Its single SF-driver design, ORZA acoustic tuning, and GAMIN calibration are presented as elements of its sound approach. The product description emphasizes balanced, detailed playback and reference-oriented tuning for creators, musicians, and listeners who care about hearing audio clearly. Those claims describe the design intent, not a guarantee that every listener will prefer its sound. Unlike the DT 770, the E3 does not offer an around-ear fit or the listed closed-back headphone construction. Its appeal is a small in-ear format and a direct analog connection, not a studio headphone setup.
The E3’s flexible, fabric-wrapped cable is described as resistant to tangling and suited to listening on the go. It also comes with a one-year manufacturer warranty. I’d look at it if I wanted wired earbuds for commuting, a compatible laptop, or a handheld gaming device, and preferred an in-ear design. I’d skip it if I want over-ear coverage, the DT 770’s stated studio-oriented 250-ohm configuration, or a wireless connection. The listing does not describe active noise cancelling, and I would not treat either product as an active noise cancelling gaming headset for commuting.
• Best for an around-ear fit → Amazon Renewed Beyerdynamic DT 770. It is explicitly an over-ear, around-ear headphone with a closed-back design. The E3 sits in the ear.
• Best for a compact wired format → Generic Sonicast direm E3. Its in-ear design is the more practical shape if you do not want to carry or wear full-size headphones on a commute.
• Best for a 3.5 mm analog in-ear option → Generic Sonicast direm E3. It is described as using a 3.5 mm wired connection and is aimed at compatible devices.
• Best for a studio setup with suitable amplification → Amazon Renewed Beyerdynamic DT 770. This listing specifies the 250-ohm model and describes it for high-powered setups and headphone amplifiers.
• Best for a long cable near a desk or interface → Amazon Renewed Beyerdynamic DT 770. Its 3 m coiled cable can extend when needed, though that length may be inconvenient when moving around.
• Best for a fabric-wrapped, tangle-resistant cable → Generic Sonicast direm E3. That cable design is a stated feature and fits its on-the-go use case.
• Best if you want a manufacturer warranty listed for one year → Generic Sonicast direm E3. The DT 770 listing specifies a 90-day limited warranty for the renewed product.
• Best for someone seeking active noise cancelling → Neither based on the listed features. The DT 770 is described with sound isolation, while the E3 is described as noise-isolating; neither listing specifies active noise cancelling.
For people comparing headphones for commuting, the E3 is the easier fit to picture if the priority is a small wired pair and the source has a headphone jack. The DT 770 can still make sense for travel when you prefer over-ear headphones and have a suitable source, but its 250-ohm configuration and coiled cable are details I would take seriously. Neither product is waterproof based on the listed information, so someone searching for waterproof ear clip headphones for commuting is looking for a different design and should not assume either of these meets that need.
My Verdict
I’d choose the Generic Sonicast direm E3 for commuting because its wired in-ear format is the more practical match for carrying and listening on the move, as long as my device has a 3.5 mm jack. I’d choose the Amazon Renewed Beyerdynamic DT 770 instead for focused home monitoring with suitable equipment. Its 250-ohm configuration and coiled cable make it the more specialized choice, not my default travel pick. For my commute, I’d buy the E3.
For a compact wired option, the direm E3 is the more natural fit because it is an in-ear model with a 3.5 mm connection. The DT 770 is an over-ear headphone with a 3 m coiled cable and a 250-ohm configuration, so I’d check the device and routine carefully before taking it as a daily travel pair.
Neither listing specifies active noise cancelling. The DT 770 is described as closed-back with sound isolation, and the E3 is described as noise-isolating. Those descriptions should not be mistaken for an active noise cancelling feature.
The listed DT 770 configuration is 250 ohms and is described for high-powered setups and headphone amplifiers. The product information identifies a wired 3.5 mm connection, but a compatible jack alone does not establish that a phone is the best source for this impedance. Check the exact device and model configuration before buying.
Choose based on the connection and wearing style you want. The E3 is an in-ear wired option listed for gaming devices, including handheld systems, when they have a compatible 3.5 mm connection. The DT 770 is an over-ear wired headphone, but its 250-ohm configuration is intended for higher-powered gear rather than being presented as an active noise cancelling gaming headset.
