Reasons Why You Should Buy Them


The Sennheiser CX 350BT has a unique and lightweight design that makes them portable and less visible during everyday activities than a round-the-neck model

The Sennheiser CX 350 BT Wireless provides a very good sound quality compared to other in-ear models. The bass is deep and punchy, but there is no feeling of excess, complimented by detailed midrange and crisp, clear treble

Built-in controls and microphone allow you to answer phone calls, control music playback, adjust volume levels, skiptracks, turn on pairing mode, power on/off, check battery status and connect with Google Assistant, Siri or Baidu

The Sennheiser Smart Control app lets you control your headphones even more, such as ability to change equalizer settings, selectvoice assistant, choose podcast mode for optimized speech, firmware updates and check battery status

Sennheiser has included four different sizes of silicone tips in the packaging to help you find the most comfortable fit

Battery life of up to 10 hours is considerably solid compared to competing models that offer an average of 6-8 hours on a single charge

Thanks to the USB Type-C charging connector, which has become the standard for most Android models these days, you only need to carry one charging cable while traveling

Compatible with high-quality codecs such as aptX, aptX LL, AAC and SBC, you can listen to your favorite songs with high-resolution audio quality

There is no problem with the quality of the calls. The people on the other side of the call hear your voice clearly even in a moderately noisy environment

With Bluetooth 5.0, you can seamlessly connect and switch between multiple devices. You can answer calls on your smartphone while listening to music on a laptop

There are two standard color options to choose from: Black and White depending on your preferences

Skullcandy Indy Evo has similar sound output, design and build quality as of Skullcandy Indy Fuel, the only difference is the lack of a wireless charging case. But on a positive side, they're available in five color options and $30 less than Indy Fuel True wireless earbuds

If you are a fitness freak, you will love the sound quality of the Skullcandy Indy Evo. 6mm dynamic driver units provide plenty of low-end bass to keep your energy high in the gym without overwhelming the vocals and instruments

The integrated TILE technology makes it easy to find the lost earbuds in your home, office, gym or cafe, open the tile app on your smartphone and let the earbuds play a sound so that you can find them

Each bud receives its own Bluetooth signal and works independently, so each bud can be used alone in solo mode to listen to music or answer phone calls

Most users will appreciate their lightweight plastic design and included silicone tips in three different sizes, as well as stability hooks that offer a secure and comfortable fit even during long listening sessions

Ambient mode is a small but convenient feature when you need to keep your ear open to outside announcements without having to remove your earbuds, such as airport announcements or traffic noise while crossing busy city streets

Bluetooth 5.0 offers a multi-device pairing that allows you to answer calls on your smartphone while listening to music on your laptop at the same time

There are three equalizer presets - Music mode, Podcast mode, and Movie mode, which can be activated from the on-board touch panel to select the audio output to your liking

The on-board microphone and touch controls allow you to answer phone calls, skip tracks, adjust volume, play/pause music, switch EQ modes, Bluetooth pairing, power on/off, Ambient mode on/off and connect with your phone’s virtual assistant

Thanks to the IP55 design for dust and splash resistance, they are perfect for outdoor activities; just wash them after a sweaty workout

Brilliant sound insulation due to the included silicone tips of three different sizes, which create the perfect seal to block most external sounds

They deliver an above-average battery life of 6 hours on a single charge and an impressive additional 24 hours of juice with the wireless charging case; they also have a quick charge feature that offers up to 2 hours of music playback with a charge of just 10 minutes

Reasons Why You Should Avoid Them


If you like heavy bass genres like Rap, Mettle, Jazz, then these in-ear headphones are not for you, better opt for Sony or Beats headphones

The bass and treble are good as long as you have a good fit, otherwise they sound thinner than they should

The two earbuds are fastened with a cable that appears a little short for some people with a larger neck

For some users, Sennheiser cx 350bt wireless earphone may not stay in the ears due to the lack of optional fins or hooks to keep them stable in the ears

It's just the color that looks good, the quality of the earbuds, the cable and the remote control feels a little cheap

The Sennheiser cx 350bt in ear headphones are not suitable for running or heavy exercise, as they keep jumping down your ears and there's nothing to hold them

A carrying case or pouch is not included in the packaging, which is somewhat disappointing

There is no “auto pause” feature when take them off from your ears, which makes them a little less convenient

Since there is no automatic shutdown mode, the battery will be completely discharged if the earphones are left connected

There is no official IPX rating that indicates how much water and dust resistant these earphones are

There are no magnets inside the earbuds like Beats X to clamp them around your neck when not in use

Skullcandy Indy Evo True Wireless Earbuds sound great, as long as you get a good fit, it is very important otherwise they sound thinner than they should

They are not for vocally oriented or laid back listening; these headphones are designed for bass heavy music like Pop, EDM, Jazz or Metal

Connecting to a second device or resetting the headset is still a long and tedious process; you have to follow many instructions that are really hard to remember

The touch sensitive on-board controls are just average and do not have good acoustic feedback, performing an action specifically selecting the EQ modes or activating/deactivating the ambient mode is a hit or miss

Bluetooth connectivity is still not very reliable; Skullcandy Indy Evo in ear True wireless headphones drop the signal and skip the tracks occasionally as you walk through the busy city streets

The inline microphone offers substandard call quality, in noisy environments it appears thin, noticeably muffled and lacks details when making calls and is only suitable for use in quiet rooms

You may notice a delay when watching 4K videos due to the lack of support for superior audio codec such as aptX, aptX HD, aptX LL, as well as LDAC and AAC

The companion app has pretty basic functionality, such as Ambient mode on/off, registering headphones, accessing user guides, and that’s all. There is no battery level indicator for the headphones or case, and you cannot change the equalizer mode for more personalized listening

Skullcandy Indy Evo Earbuds are made entirely of hard plastic, which helps maintain weight for comfortable wear, but lacks a premium touch and feel
