Strich SDP-120 vs Mosen MDP-80DS

Key Action

Both models are full size 88 key digital pianos with some form of weighted hammer action. The Strich SDP-120 is described as having fully weighted hammer action, and the Mosen MDP-80DS is listed with weighted hammer action, though its promotional text also says fully weighted. Neither listing names the exact action mechanism or manufacturer, so the feel remains unverified from published data.

The key action score is 20 out of 30 for Strich and 19 out of 30 for Mosen, which is nearly a tie. Strich gets a slight edge for using consistent fully weighted language. For beginners, either action should help build finger strength, but advanced players may find the lack of detail about pivot length and sensor type frustrating.

Piano Sound and Speakers

Strich publishes 128 note polyphony and 128 tones, giving a clear spec for how many notes can sound at once and how many instrument voices are available. Mosen also lists 128 tones but does not publish polyphony, which is an important gap when comparing sustained chords and layered sounds. Strich does not name its tone generator, but the large tone count suggests wide sonic variety.

For speakers, Strich specifies 2 by 15 watt built in speakers, while Mosen only says dual stereo speakers without wattage. The sound score is 17 out of 25 for Strich and 16 out of 25 for Mosen, reflecting Strich's more complete published audio specs. The Mosen mentions a French DREAM sound source, but Strich is silent on its sample engine. Neither model provides audio demos or velocity layer details, so actual piano tone quality cannot be confirmed from the listing.

Neither listing provides enough audio information for a confident tone comparison. Strich has the advantage of a published polyphony and speaker wattage, but Mosen names its DREAM sound source, which may indicate a specific sample architecture. Buyers who want a rich, layered piano should note that 128 note polyphony on the Strich allows many sustained notes without dropouts, while the Mosen polyphony remains unknown. Without listening, the actual character of either piano sound is unverified.

Features and Modes

Strich includes a large built in library with 200 rhythms and 110 demo songs, along with 128 tones. This is a strong set for players who want accompaniment patterns and learning material without external devices. Mosen offers 100 plus rhythms and 88 demo songs, which is still useful but numerically smaller. The features score is 11 out of 15 for Strich and 9 out of 15 for Mosen.

Mosen counteracts its smaller rhythm count with recording and playback functions and a dual keyboard mode. These tools are especially helpful for lessons, allowing a student to split the keyboard for teacher and student or record a performance for review. Strich does not mention recording or dual keyboard mode, so those capabilities may be absent. Overall, Strich leads in feature quantity, but Mosen adds specific practice tools that some beginners will value more.

Both models include headphone support for silent practice, which is confirmed in the listings. Strich does not list recording or dual keyboard, but its large rhythm and demo song count may be enough for self guided play. Mosen's recording feature is limited in description, but it still allows a student to capture performances. If you want a piano that doubles as a rhythm machine and song library, Strich is stronger, while Mosen offers more targeted functions for lesson structure.

Build, Design and Portability

Neither listing publishes weight or dimensions, so portability cannot be compared with any confidence. Both are 88 key digital pianos, which typically have a full size footprint and moderate weight, but the lack of figures leaves buyers guessing. The build and portability score is 6 out of 10 for both models, indicating parity and a shared weakness in published build details.

The cabinets are not described beyond the key count, and neither company states the materials used. Strich does not include a music stand in its accessory list, while Mosen does include one, which suggests Mosen is slightly more ready for sheet music use. Without knowing the actual size or weight, it is hard to say which is easier to move or fit into a small room. Both appear designed for stationary home practice rather than frequent transport.

Because neither manufacturer states the weight, buyers cannot compare transport effort or stand requirements. The lack of dimensions also makes it unclear how much floor space each piano needs. Strich does not list a music stand, which may force a separate purchase, while Mosen includes one. Overall, both models share the same build score and similar unknowns, so neither can claim better portability or build quality from the listing.

Connectivity

Strich offers USB, MIDI, audio inputs, and built in wireless MIDI, making it the more flexible option for connecting to computers, audio interfaces, and other MIDI equipment. Mosen provides USB, a stereo headphone output, and a sustain pedal input, but no audio inputs or wired MIDI ports. The connectivity score is 8 out of 10 for Strich and 7 out of 10 for Mosen.

Bluetooth is a key difference. Strich does not publish a Bluetooth protocol, while Mosen confirms Bluetooth support for iPhone and iPad. This means Mosen may provide simpler wireless pairing with Apple based learning apps. Strich's wireless MIDI may also support wireless use, but the listing does not detail compatible devices, and for players who need wired MIDI and audio inputs, Strich is the clear choice.

For players who want to integrate with a home studio or use MIDI controllers, Strich's audio inputs and wired MIDI ports are significant. Mosen's lack of line outputs also limits external amplification without using the headphone jack. The Bluetooth difference matters for Apple users, but Android or Windows wireless support is not specified for either model. Overall, Strich offers a more complete connection set, while Mosen offers simpler Apple wireless convenience.

Setup and Accessories

The Strich SDP-120 ships with a sustain pedal and a manual, which covers the basics but little else. The Mosen MDP-80DS includes a sustain pedal, key stickers, a music stand, and a power adapter. That makes Mosen a more complete out of box package for a first time owner.

Both sustain pedals appear to be basic switch style units, not continuous or half damper pedals. Neither listing describes a triple pedal option. For a beginner, the included pedal is enough to start, but more advanced players may want a higher quality pedal. Key stickers and a music stand give Mosen an immediate advantage for reading music and learning note names.

Daily Use

Both pianos support headphone use for quiet practice, which is essential for apartments and late night sessions. Strich's 2x15W speakers are likely loud enough for small room practice, while Mosen's speaker wattage is not published, so room filling volume is harder to predict. The 88 weighted keys on both models help develop finger strength and proper technique.

Mosen's dual keyboard mode and recording and playback can make daily lessons more engaging. A student can record a phrase and listen back, or split the keyboard for side by side practice. Strich does not list those functions, so its daily use leans more on exploring the large rhythm and demo song library. Both models offer ways to integrate with apps, but the path differs based on their connectivity options.

Daily practice on either model will be quiet with headphones and reasonably full through built in speakers. The Strich listed speaker wattage suggests it may fill a living room more predictably, while the Mosen volume remains an unknown. Both piano apps may require separate downloads, and neither listing bundles a full learning subscription. For a straightforward home practice routine, either works, but Strich has fewer question marks around its audio output power.

The Deciding Question

The core choice is between transparent performance specs and beginner focused practice tools. Strich publishes polyphony and speaker wattage, and it adds wireless MIDI, audio inputs, and a huge rhythm library. Mosen omits polyphony and speaker wattage but bundles key stickers, a music stand, recording, dual keyboard mode, and Bluetooth for Apple devices.

On paper, Strich wins with an overall score of 70 versus Mosen's 65. However, the scores do not capture physical key feel or actual piano sample quality, because neither listing provides enough detail. The deciding question is whether you need published hardware specs or a ready made lesson package. Choose based on that trade off rather than on brand reputation.

Who Should Buy Which

Buy the Strich SDP-120 if you are a budget minded player who wants a full size weighted keyboard with 128 note polyphony, 2x15W speakers, 200 rhythms, 110 demo songs, and flexible USB, MIDI, and wireless MIDI connections. It fits someone who plans to connect to a computer, use music software, or wants published speaker power for small room practice. The Strich is the better on paper choice for feature quantity and connectivity.

Buy the Mosen MDP-80DS if you are a complete beginner who values a bundled learning setup more than spec transparency. The included key stickers, music stand, power adapter, recording and playback, and dual keyboard mode make it immediately useful for lessons. Its Bluetooth support for iPhone and iPad is convenient for app based learning. Choose Mosen for convenience, but accept that polyphony and speaker wattage are not published.
