Sennheisers are known for their reliability, great sound quality and value. I was curious to test the CX 6.00BT out as they’re a cheap alternative to the significantly higher priced models. Being a Sennheiser fan, I had high hopes for the CX 6.00BT. Here’s what I found.

IN THE BOX

• CX 6.00BT In-Ear Wireless headphones
• USB charging cable
• Ear adapter set (XS/S/M/L)
• Plastic Carry case
• User Manual

FIT

The CX 6.00BT comes with ear buds in four different sizes. The earphones are close-fitting and seal well. It has nice sound isolation even on a busy street or subway. Wearing these for an extended period of time feels comfortable and the buds remain secure. Although I’m not a heavy sweater, I’ve gone running with these and they retain their in-ear stability.

BLUETOOTH FEATURES and CAPACITY

The Bluetooth controls on the CX 6.00BT are very simple. Three buttons allow you to connect, play, skip, and control calls. The earphones also come with voice prompts that notify you about incoming calls and battery life, which I find to be a helpful feature.

The microphone is decent and I haven’t had any problems with call clarity. The range on these earphones is pretty good. They work up up to at least 30 feet away, but if I turn a corner at that distance, the signal begins to drop out. The volume is high enough, which is nice because I find that some wireless brands are lacking in sufficient volume capacity.

The CX 6.00BT have a 6 hour battery life, which is about the average amount of listening time for wireless earphones. They take 1.5 hours to fully charge and there’s a fast charging option that adds a two hour charge in 10 minutes.

The earphones allow you to pair up to two devices simultaneously. Sennheiser also provides an accompanying free app that supposedly allows you to use an equalizer and perform a sound comparison test. However, using Spotify, when I tried playing around with the equalizer, I couldn’t hear any decipherable difference. So, for these wireless Sennheisers, the app seems useless. If you guys are able to work it out, shoot us an e-mail.

SOUND

As with most Sennheiser products, these earphones have a great clarity to them. In general, I found the CX 6.00BT to be too bright. Percussion and cymbals are piercing, and anything in the treble range is hard on the ears. Acoustic guitars pop, so they work well when listening to folk or country. The bass sounds clear and deep, but if you’re planning to listen to a lot of hip-hop, or you like a really warm bass, these earphones might not be your best bet. Pop and rock sounded underwhelming as well. In the mid range, that full, rich feeling was lacking. R&B sounded good on these Sennheisers, but still, there’s a consistent sibilance regardless of the style of music. Classical music is the most pleasing genre on these earphones. The soundstage has depth and the imaging gives the music a nice, articulate sound. I can’t say that I’m completely disappointed with this model, but if you like to listen at high volumes like me, emphasis in the treble and higher midrange may be too much.
