If you want a wired in-ear monitor with a hybrid driver design and a shielded, braided cable, choose Mackie MP Series In-Ear; if you need a 14.2mm planar driver and modular 3.5mm/4.4mm plugs, choose BASN ASONE PRO 14.2mm. For side sleepers, neither sheet confirms a low-profile fit suited to sleeping on your side, so I would choose based on cable and connection needs instead.
My pick is Mackie for a straightforward stage-monitor setup; BASN is the more flexible choice when your source can use either included plug.

Mackie MP Series In-Ear vs BASN ASONE PRO 14.2mm at a Glance
• Mackie MP Series In-Ear: Its dynamic-plus-balanced-armature hybrid design and shielded, braided cable are the main draws. Its trade-off is a wired 3.5mm connection rather than a choice of plug types.
• BASN ASONE PRO 14.2mm: The 14.2mm planar magnetic driver and supplied modular 3.5mm and 4.4mm plugs offer a distinctive combination. Its trade-off is that the sheet does not specify a cable braid or shielding.
• Mackie suits: Listeners and performers who want a hybrid-driver wired monitor with a swiveling, detachable MMCX connector.
• BASN suits: Musicians and careful listeners who want a planar-driver design, multiple tip materials, and a cable that can connect through either included plug.
• For side sleepers: Neither sheet specifically describes a sleep-oriented shape or confirms that either model stays comfortable when pressed against a pillow.
The Mackie MP-240 is a wired in-ear monitor built around a dynamic driver and a balanced-armature driver. That hybrid arrangement is its defining feature: the product information describes a balance of bass response, vocal clarity, and high-frequency detail. For someone monitoring music or vocals, that mix is a practical aim. The design is not presented as a single-purpose bass earphone; it is intended to cover the full listening range.
Its low-profile molded enclosure and custom ear tips are described as supporting comfort, bass response, and sound isolation. The listed isolation claim is up to 40 dB, which gives a sense of the product’s focus on blocking surrounding sound when properly fitted. That matters in a performance or listening environment where outside noise can compete with the audio. It does not, however, establish how the fit will feel for every ear, or whether the housing will be comfortable against a pillow.

The cable is shielded and braided, and the MMCX connection detaches and swivels. Those details are useful if replaceability and cable handling matter to you: a detachable connection gives more flexibility than a permanently attached cable, while the swivel can accommodate different cable positions. A hard carrying case is included for storage and transport. Skip the Mackie if you specifically need a planar magnetic driver or a supplied 4.4mm balanced plug.
BASN takes a different route with a 14.2mm planar magnetic driver. The product information associates that driver with detailed listening and a wide sound stage, while also describing the earphones as suitable for musicians, producers, and audio enthusiasts. Those descriptions point to a monitor intended for focused listening as well as performance use. They are design claims, not a guarantee that every listener will hear the same presentation.
The cable is detachable through MMCX and includes both 3.5mm and 4.4mm modular plugs. That gives the BASN a useful connection advantage over a model supplied with only one plug: you can select the plug that matches compatible source equipment without relying on a separate adapter. The package also lists silicone tips and memory-foam tips in small, medium, and large, so buyers have two materials and several supplied sizes to try for fit and isolation.
BASN describes the housing as lightweight and ergonomic, with an isolating fit intended for extended wear. The listed accessories include a storage box, a quarter-inch adapter, a cleaning brush, and a cable clip. That is a fairly complete collection for someone moving between listening and music work. Skip the BASN if you want a hybrid dynamic-and-balanced-armature design or if a shielded, braided cable is a priority.
• Best fit for a hybrid-driver preference → Mackie MP Series In-Ear. It combines dynamic and balanced-armature drivers, while BASN uses a 14.2mm planar magnetic driver.
• Best for a planar magnetic driver → BASN ASONE PRO 14.2mm. This is the clear choice if that particular driver type is what you want.
• Best for choosing between two supplied plug formats → BASN. Its modular cable includes both 3.5mm and 4.4mm plugs.
• Best for a shielded, braided cable → Mackie. The product information specifically describes both the shielding and braided construction.
• Best for a swiveling detachable connector → Mackie. Its MMCX connection is described as swiveling; both products list detachable MMCX cables.
• Best for choosing between silicone and memory-foam tips → BASN. Both types are included in small, medium, and large.
• Best for a hard carrying case → Mackie. Its package includes a molded hard case; BASN lists a white storage box.
• Best for side sleeping → Neither is a clear, data-backed pick. Both are in-ear models, but neither sheet confirms pillow-friendly housing or comfort in a side-sleeping position.
Buying Considerations
Next, consider what you mean by sound preference. Mackie’s hybrid design combines dynamic and balanced-armature drivers, and its description emphasizes bass alongside vocal and high-frequency clarity. BASN’s single 14.2mm planar magnetic driver is presented around detail and a broad sound stage. These are different design approaches, not a simple measure of which one sounds better. The sheets do not provide a direct listening comparison, so it is sensible to choose by the driver approach and intended use that matter to you.
Fit is especially important if you are searching for the best with microphone on ear headphones for side sleepers. Neither product sheet lists a microphone, so I would not choose either on that requirement. Both are in-ear models with sound-isolation features, but neither is described as open-ear. That also means someone searching for spatial audio open ear headphones for side sleepers is looking for a different type of product. Likewise, neither sheet lists multipoint connectivity; both are wired, so they do not offer wireless device-switching information to compare.
For side sleeping in particular, look beyond the general claims of comfort and ergonomic design. Mackie describes a low-profile molded enclosure, and BASN describes a lightweight ergonomic housing, but neither statement confirms comfort when an ear is pressed against bedding. The supplied ear tips may help with fit, yet the product details do not establish how either model will feel in that position. If sleeping comfort is the deciding factor, treat that as an unanswered fit question rather than assuming one is sleep-ready.
Finally, weigh cable and accessory priorities. Mackie calls out a shielded, braided cable and includes a hard case. BASN’s detachable cable offers two plug formats, and its package includes both silicone and memory-foam tips, a storage box, a cleaning brush, and a cable clip. If you are comparing overall value, consider which of those features you will actually use and check the current price on Amazon using the page’s button. The available specifications alone do not settle value for every buyer.
I would buy the Mackie MP Series In-Ear for a wired monitor setup because its hybrid drivers, shielded braided cable, and swiveling detachable MMCX connection suit the combination I would prioritize.
I would choose BASN instead if I needed the 4.4mm option, wanted to try both supplied tip materials, or specifically preferred a planar magnetic driver.
For side sleepers, I would not call either a confirmed sleep-friendly choice; neither sheet establishes pillow comfort.
My recommendation is Mackie for the simpler, durability-focused monitor package, with BASN the stronger match for plug flexibility.
FAQ
Neither product’s listed information confirms a design for side sleeping or describes comfort with the ear pressed against a pillow. Mackie is described as low-profile, while BASN is described as lightweight and ergonomic, but those details do not settle pillow comfort.
Neither data sheet lists a microphone or multipoint connectivity. Both products are described as wired, so they are not wireless multipoint headphones.
Mackie specifically describes a shielded, braided cable and a detachable MMCX connector that swivels. BASN lists a detachable MMCX cable and includes silicone and memory-foam tips in three sizes, but its sheet does not specify shielding or braiding.
