Mosen MDP-70 vs Skaehp SK-172
Quick Verdict
The Mosen MDP-70 is the better paper choice for buyers who want documented sound specs, adjustable touch sensitivity, and a triple pedal unit. Its 128-note polyphony and 128 tones give it a clearer sound foundation, and the 2x15W speakers are a known quantity. The Skaehp SK-172 wins for a modern practice setup with built-in Bluetooth audio, app connection, auto accompaniment, recording, and included Bluetooth headphones. However, its polyphony, sounds, and speaker power are not published, making its audio quality uncertain. If you prioritize traditional piano features and sound variety, choose Mosen. If you need wireless app connectivity and silent practice accessories, choose Skaehp. Both are budget weighted 88 key options with unknown weight and long-term reliability.

Key Action
Both the Mosen MDP-70 and the Skaehp SK-172 list 88 fully weighted hammer action keys. This is the most important specification for a beginner digital piano because it mimics the resistance of an acoustic piano. The listings do not name the manufacturer of either key action, so details like key texture, pivot length, and long term durability remain unknown. As a baseline, both models meet the essential requirement of a weighted hammer action.
The Mosen MDP-70 adds adjustable touch sensitivity to its key action. This feature lets a player change how the keyboard responds to finger velocity, which is useful for beginners who need a lighter touch at first or for different playing styles. The Skaehp SK-172 listing does not mention touch sensitivity adjustment, so it likely has a fixed response curve. That is not a deal breaker, but it gives the Mosen a small practical advantage.
Both models score 20 out of 30 for key action in the breakdown. That equal score reflects the fact that the core action type is the same. Without in-person testing or more detailed specifications, a buyer cannot know which keyboard feels better. The Mosen's adjustable touch sensitivity is a published differentiator, but both remain budget weighted actions with no brand credibility or durability data.
Piano Sound and Speakers
The Mosen MDP-70 has clear published sound specifications. It lists 128-note polyphony and 128 tones including piano, strings, drums, bass, and more. The 128-note polyphony is a solid number that prevents note dropout during complex sustained passages. The Skaehp SK-172 does not publish polyphony, sound count, or any details about its sound engine, so its audio performance is largely unknown from the listing.
Speaker output is another area where the Mosen has a concrete advantage. The listing states 2x15W speakers, which is a modest but serviceable power rating for home practice. The Skaehp listing does not state speaker wattage, driver size, or any audio output specifications. Because of that, a buyer cannot estimate volume levels, headroom, or sound clarity. The Mosen's published 2x15W speakers are not a guarantee of quality, but at least they are a known quantity.
Neither listing describes the sampling method or the character of the piano tone. The Mosen's 128 tones suggest a general purpose sound set, but there is no mention of multi-layer samples, string resonance, or damper resonance. The Skaehp's lack of sound engine details is a larger gap. In the scoring breakdown, the Mosen scores 18 out of 25 for piano sound, while the Skaehp scores 14 out of 25. That difference reflects the Mosen's documented specs versus the Skaehp's unknowns.
Features and Modes
Both pianos include practical learning and performance features. The Mosen MDP-70 lists dual and split modes, which allow you to layer two sounds together or divide the keyboard so each hand plays a different tone. The Skaehp SK-172 lists dual voice mode and auto accompaniment. Auto accompaniment provides backing rhythms and chords, which can make practice more engaging. Split mode on the Mosen is useful for traditional piano lessons where the left hand plays bass and the right hand plays a melody.
The Skaehp SK-172 also lists transposition, a built in metronome, and a recording function. The Mosen listing does not mention a metronome or recording function, so those features cannot be assumed. For rhythm practice and self-assessment, the Skaehp has a clear published advantage. The Mosen's dual and split modes are less common in the Skaehp listing, which only mentions dual voice, not split.
Connectivity to apps differs significantly. The Skaehp has built in Bluetooth audio and app connection, which may unlock additional lesson features or sound expansion, although the listing does not specify which apps. The Mosen has no Bluetooth listed, so its feature set is limited to the onboard sounds and modes. For a buyer who wants an all-in-one practice tool with rhythm and recording, the Skaehp offers more published features, but the Mosen's split mode is a distinct advantage for certain practice routines.
Build, Design and Portability
Portability is difficult to assess for either model because neither listing provides weight or dimensions. That is a significant omission for buyers who need to move the piano between rooms or transport it. The Mosen MDP-70 includes an X stand, which is typically lightweight and easy to set up but not the most stable option. The Skaehp SK-172 includes a keyboard stand, but the type is not specified, so it could be an X stand or a different design.
Physical build details are scarce. Neither listing mentions cabinet materials, key texture, or the layout of controls. The Mosen includes a triple pedal unit, which suggests a more traditional piano setup with soft, sostenuto, and sustain pedals. The Skaehp includes a single sustain pedal, which is simpler and more portable. The included accessories influence the overall footprint, but without weight data, a buyer cannot know how heavy or bulky either setup will be.
Both bundles appear designed for stationary home use rather than gigging. The Mosen's triple pedal unit adds bulk and wires, while the Skaehp's included Bluetooth headphones indicate a focus on silent practice at a desk or stand. The lack of published weight and dimensions for both is a drawback for anyone who values portability. Until the seller provides those numbers, treat both as home practice instruments.
Connectivity
The Skaehp SK-172 has a clear connectivity advantage because it lists built-in Bluetooth audio and app connection. That allows wireless audio streaming from a phone or tablet and connection to learning apps without cables. The Mosen MDP-70 listing does not publish Bluetooth, so you should assume it only has wired connectivity. Both models list USB MIDI, which is standard for connecting to a computer or DAW.
The Skaehp specifies USB MIDI input and output, while the Mosen simply says USB-MIDI. In practice USB MIDI is usually bidirectional, so both should work for sending and receiving MIDI data. For a beginner who wants to use apps like Simply Piano or Flowkey, the Skaehp's Bluetooth connection is more convenient because it removes the need for a USB cable. The Mosen can still connect via USB MIDI, but it is a wired-only solution.
Neither listing mentions line outputs, auxiliary inputs, or dedicated headphone jack specifications. The Skaehp includes Bluetooth headphones, which confirms there is some headphone connectivity, but the jack type is not stated. The Mosen does not list a headphone jack, though a digital piano almost certainly has one. The lack of these details is another gap in the listings. Overall, if wireless connectivity matters, the Skaehp is the obvious choice. The scoring reflects this: Mosen gets 5 out of 10 for connectivity, while Skaehp gets 8 out of 10.
Setup and Accessories
The Mosen MDP-70 includes an X stand, an adjustable music rest, a triple pedal unit, and keyboard stickers. The triple pedal unit is a significant inclusion because it provides soft, sostenuto, and sustain functions, which are useful for classical and expressive playing. The adjustable music rest is standard for holding sheet music or a tablet. The keyboard stickers help beginners learn note positions.
The Skaehp SK-172 includes a keyboard stand, a sustain pedal, and Bluetooth headphones. The Bluetooth headphones are a notable extra for silent practice, which is a common need for students in shared living spaces. The single sustain pedal is less versatile than Mosen's triple pedal unit but sufficient for basic sustain. The stand type is not specified, so its stability and height adjustment are unknown.
Neither listing includes a bench or instructional materials beyond the keyboard stickers. Assembly difficulty is not described, but both stands likely require some basic setup. The Mosen's accessory bundle is more traditional and piano-like, while the Skaehp's bundle is more modern with wireless headphones. A buyer who wants a complete conventional practice setup may prefer the Mosen. A buyer who needs silent practice from day one may prefer the Skaehp.
Daily Use
For daily practice, both models provide fully weighted hammer action, which is essential for building finger strength and technique. The Mosen's adjustable touch sensitivity is helpful for beginners who want to start with a lighter response and increase resistance over time. The Skaehp's action may be fixed, but it still provides the weighted feel. The Mosen's 128-note polyphony prevents note cutoff during sustained passages, while the Skaehp's polyphony is unknown, which could become an issue for advanced pieces.
The Skaehp's auto accompaniment and recording function can make daily practice more productive and enjoyable. A beginner can play along with rhythm patterns and record themselves to identify mistakes. Its Bluetooth app connection may offer interactive lessons, though the specific apps are not listed. The Mosen's dual and split modes allow sound experimentation, and the 128 onboard tones provide variety beyond a basic piano sound. However, the Mosen does not list a metronome or recording function, so self-assessment may require external tools.
Both models have potential limitations for daily use. The Mosen's speaker output is known at 2x15W, which should be adequate for a small room, but actual sound quality is not described. The Skaehp's speaker power is unknown, so it may be quieter or less clear. For quiet practice, the Skaehp's included Bluetooth headphones are a clear benefit. For a wide sound palette, the Mosen has more published tones. A buyer should weigh whether built-in rhythm and recording features or documented sound variety matters more for their routine.
The Deciding Question
The deciding question is whether you value documented sound performance or wireless connectivity and learning tools. The Mosen gives concrete numbers: 128-note polyphony, 128 tones, 2x15W speakers, and adjustable touch sensitivity. Those specs make it easier to compare on paper and suggest a more capable sound engine. The Skaehp's sound engine is a black box with no published polyphony or tone count, but its Bluetooth audio, app connection, auto accompaniment, and recording function are modern conveniences.
The Mosen is more appealing for a buyer who wants a traditional piano-like setup with triple pedals and a wide range of onboard sounds. Its lack of Bluetooth means you will need a wired USB MIDI connection for any app use. The Skaehp is more tailored to a buyer who plans to use learning apps, practice silently with Bluetooth headphones, and wants auto accompaniment. The Skaehp's unknown sound specifications are a risk for someone who prioritizes realistic piano tone.
Both are budget instruments with unknown long-term reliability and no published weight. The overall scores are close: Mosen 69, Skaehp 66. The three point difference comes mainly from the Mosen's stronger piano sound score of 18 versus Skaehp's 14. If you trust the published numbers, the Mosen is slightly better on sound. If you value wireless features and silent practice, the Skaehp is more convenient. Neither listing provides enough information to guarantee a great purchase, so buyers should seek additional details from the seller where possible.
Who Should Buy Which
Choose the Mosen MDP-70 if you want a budget 88 key weighted piano with published sound specs, adjustable touch sensitivity, and a triple pedal unit. It suits beginners who want a traditional home piano setup with a stand and a wide range of onboard tones. The 128-note polyphony and 2x15W speakers are documented, which reduces some uncertainty. If you do not need Bluetooth and are comfortable using a wired USB MIDI connection, the Mosen is a solid paper choice.
Choose the Skaehp SK-172 if you want a budget 88 key weighted piano with built-in Bluetooth audio, app connection, auto accompaniment, recording, and included Bluetooth headphones. It suits students who learn with apps, practice in shared spaces, and need a complete silent practice bundle. The single sustain pedal is sufficient for basics, and the auto accompaniment can make practice more engaging. You accept that the sound engine details are not published.
If you are still undecided, think about your most common practice scenario. If you will play through built-in speakers with headphones only occasionally and want a more traditional pedal setup, the Mosen is the better match. If you will use apps daily, record your practice, and rely on Bluetooth headphones for quiet sessions, the Skaehp is the better fit. Both pianos are budget 88 key weighted options, so the choice comes down to which set of published features matters more to you.
