Price Comparison
The Casio Privia PX-870 is priced at $999.00, while the UMOMO U-720 is significantly cheaper at $329.98, making it about 67% less expensive. This price difference may be a crucial factor for those on a budget or for beginners looking to start their musical journey without a large financial commitment. Although the UMOMO U-720 offers a more accessible entry point into digital pianos, potential buyers should consider how the features and sound quality of each model justify their respective prices.
Sound Quality
The Casio Privia PX-870 delivers an immersive grand piano sound through its AiR Sound Source, which recreates the depth of a concert grand piano with advanced features like damper and string resonance. It boasts a powerful 40W sound system with four speakers, providing rich sound that fills a room. In contrast, the UMOMO U-720 features built-in stereo speakers but lacks the advanced sound projection capabilities or the same level of sound quality as the Casio. For serious musicians or those prioritizing sound fidelity, the Casio's offerings may be more appealing.
Key Action and Feel
When it comes to key action, the Casio Privia PX-870 features 88-key Tri-Sensor II Scaled Hammer Action keys that replicate the touch and feel of a traditional piano with simulated ebony and ivory textures. This design aims to provide a realistic playing experience with superior dynamic control. The UMOMO U-720, while offering a full 88-key setup, does not specify advanced key action technology, which may result in a less authentic feel during play. For players seeking an authentic piano experience, the Casio stands out.
Features and Functionality
The Casio Privia PX-870 includes numerous features designed for learning and performance, such as Duet Mode, dual headphone jacks, and 60 built-in songs. It also has a 2-track MIDI recorder and Concert Play, which allows users to play along with orchestral backing tracks. In comparison, the UMOMO U-720 offers a variety of functionalities, including 680 tones, 600 rhythms, and 80 demo songs, along with a 3-pedal system. While both pianos provide useful features, the Casio’s focus on performance-oriented functionalities may appeal more to intermediate and advanced players.
Design and Aesthetics
The Casio Privia PX-870 boasts a sleek console design that includes a sliding key cover, making it an attractive addition to any room. Its modern aesthetic is not only functional but also complements various home decors. On the other hand, the UMOMO U-720 features a more utilitarian design with a piano stand and storage bench but may not have the same level of elegance as the Casio. For buyers who value style along with functionality, the design of the Casio may be a significant factor in their decision.
Portability
The UMOMO U-720 is designed with portability in mind, being easier to assemble and set up, as noted in its product description. It also comes with a headphone jack, making it suitable for quiet practice, appealing to beginners who may not want to disturb others. Conversely, the Casio Privia PX-870, while it has a modern design, might not be as easy to move or set up compared to the UMOMO. For those who prioritize portability, the UMOMO U-720 could be the better option.
Brand Reputation and Sales Rank
Casio has a long-standing reputation for producing high-quality musical instruments, and the Privia PX-870 ranks 14,122 in sales, indicating a strong presence in the market. The UMOMO U-720, with a sales rank of 19,173, is also gaining traction among learners and casual players. While both brands have their merits, Casio’s established reputation and higher sales rank may provide additional confidence for buyers seeking reliability in their purchase.
Which should you buy?
Ultimately, the decision between the Casio Privia PX-870 and the UMOMO U-720 hinges on individual needs and budget. The Casio offers superior sound quality, realistic key action, and advanced features that cater to more serious musicians, albeit at a higher price point of $999.00. The UMOMO, priced at $329.98, provides a more budget-friendly option with decent features for beginners and casual players. If you're looking for a high-quality, feature-rich digital piano, the Casio Privia PX-870 is the way to go. However, if you're just starting out and need a functional and affordable instrument, the UMOMO U-720 could serve you well.
