First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.
Sennheiser HD 418 headphones
The headphones in Sennheiser's HD 400 series come with stylish designs and different sound signatures.
- Ergonomic design, good build quality
- Poor high extensions, Unrefined mids and bass, slight distortion at loud volume
Sennheiser's HD 418 headphones have comfortable design and are designed for iPod and portable media players. In terms of sound quality, the headphones offered warm sound but lacked refinement when it comes to details and resolution. They would be just fine for casual listeners but audiophiles would be disappointed by the muffled sound.

Sennheiser's HD 418 is a pair of entry-level over-the-ear headphones that promises powerful bass-driven sound while providing extra comfort to users. After testing them for weeks, here is our impression.
Sennheiser HD 418: Design and Features
The Sennheiser HD 418 has a funky design moulded into its plastic body and this flashy artwork would surely attract people looking for a distinctive look. Its build quality is good for constant daily usage, though the hinges which hold both the earphones may need a little care as they feel weak.
The Sennheiser HD 418 is a circumaural full-size pair of headphones with a close-back design which blocks out much of the outside noise and leaks less sound than headphones with open-back design. The single-sided cable (attached to the left earphone) makes cable less prone to tangle and clears away the clutter.
The headphones are lightweight at 380g and the ear cups cover the ears well and feel comfortable. The head-band can be adjusted to fit different head sizes and it is padded well which made wearing these cans really comfortable. In terms of fitting and wearing the headphones, we had no complaints even after 8 hours of usage.
However, due to the cushioned earpad and close-back design, our ears used to get a bit warm at normal room temperature after long use which can become an issue during summer.
The singe cable measures 1.4m which is good enough to use with your MP3 player or iPod, but quite limited for PC use unless you have front audio port. The non-detachable cable is an oxygen free copper type which is supposedly good for enhancing low frequency and the cable uses a gold plated 3.5mm straight connector.
Sennheiser HD 418: Features
The Sennheiser HD 418 is a standard dynamic headphone and employs two neodymium magnets on both the drivers. The rated frequency response is 20Hz-20kHz which is in line with most headphones in this price range and its impedance is rated at 24 Ohms. It has l<0.1% THD (Total Harmonic Distortion) and SPL is rated at 108dB. The overall feature-set is quite decent for headphones in this price range.
Sennheiser HD 418: Sound Quality
The headphones sounded loud enough with iPods, Apple's iPhone, PCs and laptops, so they won't require a separate amp.
However, with players like Cowon D2 or J3, including most multimedia phones, they sounded a bit underpowered and we usually had to plug in our portable FiiO E5 headphones amplifier; not necessarily for more loudness but rather to hear more details.
In the first listening, the most noticeable fact was the headphones' overall warm sound signature. They definitely offered warm and punchy bass, which would impress casual listeners but we still felt it could have done better in terms of depth and details.
Amidst the mids, lower mids were also more prevalent and were more pronounced than the rest of the frequencies. However, the overall mids including the higher mids sounded slightly muffled which made us crave for more resolution and details. Guitars and male vocals sounded good but the unrefined upper mids and the highs with poor extension made the overall sound lacking transparency.
Soundstage and stereo separation were on par but the overall sound reproduction needs better refinement. The headphones also tend to distort at louder volumes. Overall, the HD 418 failed to deliver well-refined and analytical sound. However, if you're looking for a pair of full-sized headphones that is comfortable to wear and offers a warm sound signature with average details, they would fit the bill.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.
The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.
My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
